How do I fix GHSA-6v73-fgf6-w5j7?

Update org.springframework.cloud:spring-cloud-function-context to version 3.2.3 or later. Run your dependency manager's update command and verify no transitive dependencies pin the vulnerable version. Use O3 Security's SCA scanner to confirm the fix is applied across your entire dependency tree.

Is GHSA-6v73-fgf6-w5j7 actively exploited in the wild?

Yes. There are 35 known exploit references for GHSA-6v73-fgf6-w5j7, including 1 documented proof-of-concept exploit on Exploit-DB and 20 in-the-wild exploitations observed on GitHub and other sources. 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-6v73-fgf6-w5j7?

GHSA-6v73-fgf6-w5j7 has an EPSS (Exploit Prediction Scoring System) score of 94.5%, 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-6v73-fgf6-w5j7 in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-6v73-fgf6-w5j7 (VMware Tanzu Spring Cloud Function Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-08-25. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-09-15. 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-6v73-fgf6-w5j7?

GHSA-6v73-fgf6-w5j7 is classified as Code Injection (CWE-94), Expression Language Injection (CWE-917). These weakness types 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-6v73-fgf6-w5j7?

A Nuclei detection template exists for GHSA-6v73-fgf6-w5j7, 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-6v73-fgf6-w5j7 published, and has it been updated?

GHSA-6v73-fgf6-w5j7 was published on April 3, 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.
