Block (Cash App)
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: Block, the parent company of Cash App, faced a significant data breach in December 2021 when a former employee unlawfully downloaded personal information of approximately **8.2 million Cash App users**. The breach was not disclosed until **April 4, 2022**, nearly four months later, raising concerns about transparency and data security practices. Shareholders filed a class-action lawsuit, alleging Block misled investors by failing to disclose inadequate security measures before the breach and during its $29 billion acquisition of Afterpay. While the lawsuit was dismissed due to lack of evidence of fraudulent intent, the incident exposed vulnerabilities in Block’s data protection framework. Additionally, Block settled separate regulatory cases in 2024, paying **$80 million** to 48 states and **$40 million** to New York for anti-money laundering deficiencies in Cash App. The breach involved **customer data leakage**, though no ransomware was reported. Cash App, with **57 million monthly users** and **$283 billion in inflows (2024)**, faced reputational and financial risks, though the direct operational impact appeared contained to data exposure and legal repercussions.

Description
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.
