Overview

PayRange is a mobile payment app that allows users to pay for vending machines, laundromats, and other unattended machines using a smartphone with Bluetooth. Two vulnerabilities were discovered in version 7.0.7 of the PayRange app that is available in the Google Play store.

Description

A vulnerability (CVE-2026-13462) exists in the PayRange Android app that causes invalid SSL certificates to be accepted in application WebViews. A second vulnerability (CVE-2026-13461) exists that allows the injection of JavaScript, which can be used to escape the WebView sandbox and perform a number of dangerous actions on the user's device. These vulnerabilities were discovered in version 7.0.7 of the PayRange app.

The PayRange app bypasses Android's SSL trust chain and accepts certificates that match any of the following rules (including self-signed certificates):

• Common Name ends with "payrange.com"
• Common Name contains "stripe.com"
• Common Name contains "fetlifestatus.com" AND any of these conditions are true:
• Issuer Common Name is "R10"
• Issuer Common Name is "R3"
• Issuer Common Name contains "Network Solutions"

The attack vector is an on-path interception. If an attacker can direct traffic intended for a legitimate server to a device they control, they can negotiate a TLS connection with the user's device using any trusted certificate that matches the rule set. They are then able to inject content into the WebView and harvest credentials, issue malicious requests and read data entered by the user, including exchanges with the PayRange and Stripe servers.

Impact

An attacker may be able to intercept any information they can convince the user to send through the app. If the user is a machine operator, the injected JavaScript code can also connect to PayRange hardware and issue commands with the full permissions of the operator.

Solution

Unfortunately, we were unable to reach the vendor to coordinate this vulnerability. Apply the latest software updates provided by your hardware or software vendor as they become available.

Overview

Two vulnerabilities have been discovered in Xerte Online Toolkits, an open-source e-learning authoring toolsuite intended for the creation of learning materials within a web browser. CVE-2026-14261 tracks the persistence of the /setup/ directory after installation, which allows an unauthenticated attacker to reconfigure the application to point to a remote database they control in order to gain administrative access. CVE-2026-12116 tracks an editable antivirus binary path that can be redirected to a PHP interpreter, causing uploaded files to be executed as PHP code and resulting in remote code execution (RCE). Version v3.15.5 or v3.14.6 of Xerte Online Toolkits fixes these vulnerabilities.

Description

Xerte Online Toolkits is a suite of a free, open-source e-learning authoring tools that allows users to make educational materials directly in-browser. The toolset is installed from multiple packages, and creates a setup folder that persists after installation.

CVE-2026-14261
A vulnerability in Xerte Online Toolkits allows for authentication bypass and remote code execution via reinstallation through the /setup/ folder, enabling attackers to reinstall the service to a remote database they control.

CVE-2026-12116
A vulnerability in Xerte Online Toolkits allows for RCE through the antivirus binary path in the tools server settings. The antivirus binary runs on all uploaded files, but the path to the binary can be modified using the configuration menu. An attacker can achieve remote code execution by redirecting the path to a PHP interpreter, causing any uploaded PHP scripts to be executed.

During installation, Xerte creates a /setup/ folder to configure database connection settings. This folder persists post-installation without access controls or automatic cleanup, and /setup/index.php does not verify whether installation has completed. An attacker can revisit /setup/ and reconfigure the application to point to a remote database, thereby gaining administrative access.

After gaining admin privileges, an attacker can abuse CVE-2026-12116 by editing the antivirus binary path to point to a PHP interpreter. This causes any new uploaded files to be passed to the PHP runtime through website_code/php/import/fileupload.php, bypassing file extension checks and resulting in remote code execution.

Impact

Successful exploitation can allow full remote code execution on the affected server. This enables attackers to establish persistent access, exfiltrate data, or launch supply chain attacks by injecting malicious content into educational materials distributed by the platform.

Solution

These issues have been addressed in two commits:
- 8fec660 removes /setup/ automatically after installation/upgrade and blocks reuse.
- 8ef2062 moves sensitive configuration files, including the antivirus binary path, to server-side locations.

Users should take the following steps immediately:
1. Manually remove the initial installation /setup/ folder from installations.
2. Upgrade to Xerte v3.15.5 or v3.14.6 and run upgrade.php, which enforces automatic /setup/ removal and includes security hardening. If removal fails, the updated code still prevents exploitation.
This blog post: https://www.xerte.org.uk/index.php/en/news/blog/80-news/364-xerte-3-14-and-3-15-important-security-update contains more information and contact data for Xerte.

Overview

Adalo’s no‑code application platform exposes complete user records through its database API for all applications built on both V1 and V2. Due to a platform-level flaw, authenticated users can retrieve full user data belonging to any Adalo application, regardless of configuration. This issue affects more than one million applications and placing developers and their end users at risk of data exposure that they cannot prevent or remediate.

Description

Adalo is a Software-as-a-Service (SaaS) provider for building no-code applications. In theory, each application or tenant (customer) is logically isolated with separate databases, users, and configurations.

CVE-2026-10706 Unrestricted Disclosure of Full User Records
The Adalo database API contains a flaw which allows the backend to return complete user records for every list component request, regardless of which fields the component is configured to display. The database does not enforce ownership‑aware, server‑side authorization checks, allowing authenticated users of any Adalo application to query database and table identifiers belonging to other applications and retrieve full records, including fields not requested. This issue is amplified by the permissive CORS policy, plaintext storage of all text files and evidence suggests that deleted records may remain accessible.

CVE-2026-10708 Exposure and Reuse of Long-Lived JWT Tokens
The JWT tokens are visible in client‑side requests and remain valid for approximately twenty days. Once copied, they can be reused from any external website or script to query the database API directly. Because the platform allows requests from any origin, attackers can repeatedly query the API and extract large volumes of user data without interacting with the application itself. The combination of exposed tokens, permissive CORS behavior, and large response limits enables persistent, automated harvesting of entire user databases using only a single token obtained from any visitor session.

Impact

These vulnerabilities affect all Adalo applications across both V1 and V2. Because they occur at the platform level, the entire population of Adalo‑built applications is impacted.

Exposure of Sensitive Information to an Unauthorized attacker (CVE-2026-10706) Attackers may extract full user records and correlate user behavior across multiple applications via dbId enumeration. The platform does not implement data minimization, privacy by design, or implement appropriate technical safeguards, allowing sensitive information to be exposed to unauthorized parties.

Insufficiently Protected Credentials (CVE-2026-10708) This vulnerability enables large‑scale data harvesting without requiring app‑specific secrets. A single request to a minimal leaderboard component may return user records containing emails, UUIDs, and custom fields. The combination of wildcard CORS behavior, long‑lived twenty‑day JWTs, and the absence of token revocation allows attackers to gather sensitive personal information from any Adalo application.

Solution

Adalo contains an access control weakness that may allow unauthorized users to bypass application boundaries under certain conditions. Adalo has acknowledged the issue, however, no patch is currently available. Customers and tenants should assume data in Adalo collections may be exposed, and avoid storing sensitive information there until a patch is deployed. Users should remain aware of increased phishing and identity theft risks and monitor their accounts for suspicious activity.

Overview

Several versions of Tenda firmware contain an undocumented authentication backdoor that grants administrative access to the devices' web management interfaces. An attacker can expoit this vulnerability, tracked as CVE-2026-11405, to bypass the password verification process and obtain full administrative control without valid credentials.

Affected Versions:
* US_FH1201V1.0BR_V1.2.0.14(408)_EN_TD
* US_W15EV1.0br_V15.11.0.5(1068_1567_841)_EN_TDE
* US_AC10V1.0re_V15.03.06.46_multi_TDE01
* US_AC5V1.0RTL_V15.03.06.48_multi_TDE01
* US_AC6V2.0RTL_V15.03.06.51_multi_T

Description

Tenda is a supplier of home and business network devices such as routers, switches, wireless access points, and video surveillance equipment. Most of these devices include web-based interfaces that allow users to perform configuration and management operations, which are protected by username/password authentication to prevent unauthorized modifications.

The web server binary /bin/httpd contains an undocumented backdoor authentication mechanism in the login() function. Initially, the function follows a normal authentication path using MD5-based password verification. However, if authentication fails, the function invokes GetValue("sys.rzadmin.password") to retrieve an alternate password value from the device configuration. It then performs a direct strcmp() comparison in plaintext between the user-supplied password and the configuration-stored value. A successful match grants role=2 admin-level access and creates a valid session.

The associated username is not validated, so any provided username will succeed when paired with the backdoor password. This backdoor authentication mechanism is not documented or visible through any administrative interface.

Impact

Successful exploitation grants full administrative access to the device's web interface, regardless of the configured administrator account credentials. With administrative control, an attacker can reconfigure the device, alter network settings, and disable security features, enabling broader compromise of the local network.

Solution

Unfortunately, we were unable to reach the vendor to coordinate this vulnerability. Since a patch is unavailable, we can only offer mitigation strategies. The following workarounds can help mitigate this vulnerability's impact until a fixed version is released:

Disable remote management on your device
If your device supports remote web management, disable it. Disabling this feature prevents attackers on external networks from accessing your device’s administrative dashboard over the internet.

Restrict local network exposure
Changing the default LAN IP address may reduce opportunistic discovery by automated scanners that target known default IP ranges. Note that this measure does not prevent deliberate or targeted network scanning.

Overview

HP Printers in the Deskjet 2800 Series running firmware version <=TBP1CN2612AR contain a missing authorization vulnerability tracked as CVE-2026-13753. This vulnerability allows unauthenticated access to the printer's webserver API endpoints, exposing Wi-Fi credentials, management configuration details, and sensitive security data normally restricted to administrative users.

Description

Modern HP printers provide a web-based management interface for configuring content such as Wi-Fi Direct settings, SNMP management access, and device security options. When accessed normally through the browser interface, these pages explicitly require administrator credentials before sensitive information is displayed. This information is protected because, for example, Wi-Fi Direct controls the printer's direct wireless connectivity, and SNMP configuration settings can reveal detailed information about the device's monitoring and management controls.

In affected firmware versions, the authorization requirement can be bypassed by sending direct, unauthenticated GET requests to multiple backend API endpoints. The affected endpoints return administrative configuration data without validating session state or authentication, including the Wi-Fi Direct SSID and plaintext passphrase, unique printer serial numbers and service IDs, and details about the device's administrative password state. This information is freely disclosed even though the corresponding web interface pages correctly enforce authentication, indicating an authorization flaw in the API layer.

Impact

A remote attacker with network access to the printer can bypass the web interface's authentication requirements and retrieve sensitive configuration data directly from backend APIs. Exposed information includes Wi-Fi Direct credentials, SNMP configuration details, device identity information, cloud service registration metadata, and other information involving the device's administrative security state. An attacker could use this information to gain unauthorized wireless access, perform reconnaissance on network or cloud integrations, impersonate the device, or facilitate further compromise of the printing environment.

Solution

Unfortunately, we were unable to reach HP to coordinate this vulnerability, so a firmware patch is not yet available. To limit the risk of this vulnerability, users should restrict network access to the printer's web interface by placing the device on a trusted or isolated network segment, disable Wi‑Fi Direct if it is not required, and limit SNMP access to trusted systems or disable it entirely. Firewall or access-control list (ACL) rules should be used to prevent untrusted hosts from reaching the printer's management ports, and discovery or cloud service features that are not needed should be disabled.
