Which packages are affected by GHSA-83fp-hh9m-c2jq?

GHSA-83fp-hh9m-c2jq affects the following packages: Piranha (NuGet). Ecosystems affected: NuGet.

How do I fix GHSA-83fp-hh9m-c2jq?

No patched version of Piranha has shipped for GHSA-83fp-hh9m-c2jq 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-83fp-hh9m-c2jq in my NuGet dependencies?

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

How do I mitigate GHSA-83fp-hh9m-c2jq 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-83fp-hh9m-c2jq?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-83fp-hh9m-c2jq can be triaged on real exposure rather than presence alone.

Is GHSA-83fp-hh9m-c2jq actively exploited in the wild?

No public exploit code has been indexed for GHSA-83fp-hh9m-c2jq 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-83fp-hh9m-c2jq?

GHSA-83fp-hh9m-c2jq has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 12th 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.

What type of vulnerability is GHSA-83fp-hh9m-c2jq?

GHSA-83fp-hh9m-c2jq is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-83fp-hh9m-c2jq published, and has it been updated?

GHSA-83fp-hh9m-c2jq was published on December 22, 2025 and was last updated on December 22, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
