Description

phpMyFAQ 3.1.12 contains a CSV injection vulnerability that allows authenticated users to inject malicious formulas into their profile names. Attackers can modify their user profile name with a payload like 'calc|a!z|' to trigger code execution when an administrator exports user data as a CSV file.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for thorsten/phpmyfaq, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of thorsten/phpmyfaq for GHSA-x2v3-9p22-w3x6. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
