Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: The California Office of the Attorney General disclosed a **data breach** affecting **LinkedIn Corporation** in **June 2016**, stemming from an earlier **2012 incident** that was rediscovered. The breach exposed **117 million user accounts**, compromising **email addresses, hashed passwords, and LinkedIn member IDs**. Although passwords were invalidated for accounts created before 2012 as a mitigating measure, the incident highlighted significant vulnerabilities in LinkedIn’s historical security practices. The exposed data, while hashed, posed risks of credential stuffing, phishing, and unauthorized account access if decryption attempts succeeded. The breach did not involve financial or highly sensitive personal data (e.g., Social Security numbers), but the scale of exposed credentials—one of the largest at the time—undermined user trust and required widespread password resets. LinkedIn faced reputational damage and regulatory scrutiny, though no direct financial fraud or identity theft was reported as a direct consequence of this specific breach.

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.

Description
Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.

Description
Neuron is a PHP framework for creating and orchestrating AI Agents. Versions 2.8.11 and below use MySQLSelectTool, which is vulnerable to Read-Only Bypass. MySQLSelectTool is intended to be a read-only SQL tool (e.g., for LLM agent querying, however, validation based on the first keyword (e.g., SELECT) and a forbidden-keyword list does not block file-writing constructs such as INTO OUTFILE / INTO DUMPFILE. As a result, an attacker who can influence the tool input (e.g., via prompt injection through a public agent endpoint) may write arbitrary files to the DB server if the MySQL/MariaDB account has the FILE privilege and server configuration permits writes to a useful location (e.g., a web-accessible directory). This issue is fixed in version 2.8.12.
