How severe is GHSA-x33v-f3gp-gw2c?

No CVSS score has been assigned to GHSA-x33v-f3gp-gw2c yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-x33v-f3gp-gw2c?

GHSA-x33v-f3gp-gw2c affects the following packages: pymongo (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-x33v-f3gp-gw2c?

Update pymongo to 2.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x33v-f3gp-gw2c is resolved across your whole dependency graph.

How do I detect GHSA-x33v-f3gp-gw2c in my PyPI dependencies?

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

How do I mitigate GHSA-x33v-f3gp-gw2c if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-x33v-f3gp-gw2c actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-x33v-f3gp-gw2c, including 1 in-the-wild exploitation 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-x33v-f3gp-gw2c?

GHSA-x33v-f3gp-gw2c has an EPSS (Exploit Prediction Scoring System) score of 4.1%, placing it in the 91th 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-x33v-f3gp-gw2c published, and has it been updated?

GHSA-x33v-f3gp-gw2c was published on May 14, 2022 and was last updated on October 15, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
