Description: On **May 3, 2024**, The Lincoln National Life Insurance Company suffered a **data breach** resulting in the **inadvertent disclosure of personal information** belonging to **two individuals**. The exposed data included **Social Security numbers (SSNs)**, a highly sensitive form of personally identifiable information (PII) that significantly elevates the risk of **identity theft and financial fraud**. In response, the company offered **identity theft protection services** to the affected individuals, acknowledging the severity of the exposure. The breach was formally reported to the **Maine Office of the Attorney General** on **May 15, 2024**, indicating a delay in public disclosure. While the scale of affected individuals appears limited (only two), the nature of the compromised data—SSNs—poses **long-term risks**, as such information can be exploited for fraudulent activities like loan applications, tax fraud, or unauthorized account openings. The incident underscores vulnerabilities in the company’s **data handling and protection protocols**, particularly concerning **internal controls for safeguarding sensitive customer information**. Although no evidence suggests malicious external hacking, the **unintentional exposure** still qualifies as a **serious data leak**, warranting regulatory scrutiny and potential reputational damage. The provision of identity protection services reflects an attempt to mitigate harm, but the breach highlights the need for **strengthened data governance** to prevent future occurrences.

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.
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.
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.
Okta Java Management SDK facilitates interactions with the Okta management API. In versions 11.0.0 through 20.0.0, race conditions may arise from concurrent requests using the ApiClient class. This could cause a status code or response header from one request’s response to influence another request’s response. This issue is fixed in version 20.0.1.
The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. When using versions 4.11.0 through 4.11.2 and 4.12.0, simultaneous requests on the same client may result in improper lookups in the TokenRequestCache for the request results. This issue is fixed in versions 4.11.2 and 4.12.1.
