How severe is GHSA-8vj2-vxx3-667w?

GHSA-8vj2-vxx3-667w has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-8vj2-vxx3-667w?

GHSA-8vj2-vxx3-667w affects the following packages: pillow (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-8vj2-vxx3-667w?

Update pillow to 9.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8vj2-vxx3-667w is resolved across your whole dependency graph.

How do I detect GHSA-8vj2-vxx3-667w in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pillow. 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-8vj2-vxx3-667w 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-8vj2-vxx3-667w?

O3 pinpoints whether GHSA-8vj2-vxx3-667w 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-8vj2-vxx3-667w actively exploited in the wild?

No public exploit code has been indexed for GHSA-8vj2-vxx3-667w 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-8vj2-vxx3-667w?

GHSA-8vj2-vxx3-667w has an EPSS (Exploit Prediction Scoring System) score of 3.4%, placing it in the 87th 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-8vj2-vxx3-667w published, and has it been updated?

GHSA-8vj2-vxx3-667w was published on January 12, 2022 and was last updated on October 14, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

PIL.ImageMath.eval in Pillow before 9.0.0 allows evaluation of arbitrary expressions, such as ones that use the Python exec method ImageMath.eval("exec(exit())").

While Pillow 9.0.0 restricted top-level builtins available to PIL.ImageMath.eval(), it did not prevent builtins available to lambda expressions. These are now also restricted in 9.0.1.
