Which packages are affected by GHSA-pg2w-x9wp-vw92?

GHSA-pg2w-x9wp-vw92 affects the following packages: requests (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-pg2w-x9wp-vw92?

Update requests to 2.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pg2w-x9wp-vw92 is resolved across your whole dependency graph.

How do I detect GHSA-pg2w-x9wp-vw92 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for requests, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-pg2w-x9wp-vw92 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-pg2w-x9wp-vw92?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-pg2w-x9wp-vw92 can be triaged on real exposure rather than presence alone.

Is GHSA-pg2w-x9wp-vw92 actively exploited in the wild?

No public exploit code has been indexed for GHSA-pg2w-x9wp-vw92 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-pg2w-x9wp-vw92?

GHSA-pg2w-x9wp-vw92 has an EPSS (Exploit Prediction Scoring System) score of 3.4%, placing it in the 88th 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-pg2w-x9wp-vw92 published, and has it been updated?

GHSA-pg2w-x9wp-vw92 was published on May 13, 2022 and was last updated on December 1, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
