Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Validating String Parameter Plugin 2.4 and earlier does not escape regular expressions in tooltips. Additionally, Validating String Parameter Plugin 2.4 does not escape parameter names and parameter descriptions.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.

Validating String Parameter Plugin 2.5 escapes regular expressions in tooltips and parameter names. Parameter descriptions are rendered using the configured markup formatter.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:validating-string-parameter. 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.

  2. Fix

    Update org.jenkins-ci.plugins:validating-string-parameter to 2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fvwh-wv43-8qj5 is resolved across your whole dependency graph.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-fvwh-wv43-8qj5 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-fvwh-wv43-8qj5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
