How do I fix GHSA-jvxx-v45p-v5vf?

No patched version of rsshub has shipped for GHSA-jvxx-v45p-v5vf yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect GHSA-jvxx-v45p-v5vf in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rsshub. 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-jvxx-v45p-v5vf 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-jvxx-v45p-v5vf?

O3 pinpoints whether GHSA-jvxx-v45p-v5vf 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-jvxx-v45p-v5vf actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-jvxx-v45p-v5vf, 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-jvxx-v45p-v5vf?

GHSA-jvxx-v45p-v5vf has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 65th 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-jvxx-v45p-v5vf published, and has it been updated?

GHSA-jvxx-v45p-v5vf was published on June 23, 2022 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
