Description

A Remote Code Execution (RCE) vulnerability was discovered in the Any23 YAMLExtractor.java file and is known to affect Any23 versions < 2.5. RCE vulnerabilities allow a malicious actor to execute any code of their choice on a remote machine over LAN, WAN, or internet. RCE belongs to the broader class of arbitrary code execution (ACE) vulnerabilities.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.any23:apache-any23, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.any23:apache-any23 to 2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99px-7724-484v is resolved across your whole dependency graph.

  3. Workarounds

    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.
