How severe is GHSA-f556-49jc-4rvc?

GHSA-f556-49jc-4rvc has a CVSS score of 5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-f556-49jc-4rvc?

GHSA-f556-49jc-4rvc affects the following packages: ansible (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-f556-49jc-4rvc?

Update ansible to 2.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f556-49jc-4rvc is resolved across your whole dependency graph.

How do I detect GHSA-f556-49jc-4rvc in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ansible. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-f556-49jc-4rvc if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against GHSA-f556-49jc-4rvc?

O3 pinpoints whether GHSA-f556-49jc-4rvc is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-f556-49jc-4rvc actively exploited in the wild?

No public exploit code has been indexed for GHSA-f556-49jc-4rvc yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-f556-49jc-4rvc?

GHSA-f556-49jc-4rvc has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th 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. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-f556-49jc-4rvc published, and has it been updated?

GHSA-f556-49jc-4rvc was published on October 31, 2025 and was last updated on October 31, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

A flaw was found in Ansible Base when using the aws_ssm connection plugin as its garbage collector is not happening after the playbook run is completed. Files would remain in the bucket exposing the data. This issue directly affects data confidentiality.
