A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is GHSA-jc35-q369-45pv in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-jc35-q369-45pv (Apache Struts Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2021-11-03. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-05-03. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is GHSA-jc35-q369-45pv?

GHSA-jc35-q369-45pv is classified as Expression Language Injection (CWE-917). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for GHSA-jc35-q369-45pv?

A Nuclei detection template exists for GHSA-jc35-q369-45pv, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-jc35-q369-45pv published, and has it been updated?

GHSA-jc35-q369-45pv was published on February 9, 2022 and was last updated on October 22, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
