Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-2p6p-9rc9-62j9?

GHSA-2p6p-9rc9-62j9 has an EPSS (Exploit Prediction Scoring System) score of 93.9%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is GHSA-2p6p-9rc9-62j9 in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-2p6p-9rc9-62j9 (Craft CMS Code Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-06-02. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-06-23. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. 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-2p6p-9rc9-62j9?

GHSA-2p6p-9rc9-62j9 is classified as Code Injection (CWE-94). 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-2p6p-9rc9-62j9?

A Nuclei detection template exists for GHSA-2p6p-9rc9-62j9, 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-2p6p-9rc9-62j9 published, and has it been updated?

GHSA-2p6p-9rc9-62j9 was published on December 18, 2024 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.
