HIGHCross-site Scripting in Jenkins Autocomplete Parameter Plugin
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Jenkins Autocomplete Parameter Plugin 1.1 and earlier does not escape the name of Dropdown Autocomplete and Auto Complete String parameters on views displaying parameters. This results in stored cross-site scripting (XSS) vulnerabilities exploitable by attackers with Item/Configure permission.
Exploitation of this vulnerability requires that parameters are listed on another page, like the "Build With Parameters" and "Parameters" pages provided by Jenkins (core), and that those pages are not hardened to prevent exploitation. Jenkins (core) has prevented exploitation of vulnerabilities of this kind on the "Build With Parameters" and "Parameters" pages since 2.44 and LTS 2.32.2 as part of the SECURITY-353 / CVE-2017-2601 fix. Additionally, several plugins have previously been updated to list parameters in a way that prevents exploitation by default, see SECURITY-2617 in the 2022-04-12 security advisory for a list.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:autocomplete-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.
Remediation status
No patched version of org.jenkins-ci.plugins:autocomplete-parameter has shipped for GHSA-ppwv-mvqg-q89h yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 pinpoints whether GHSA-ppwv-mvqg-q89h 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-ppwv-mvqg-q89h. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-ppwv-mvqg-q89h in your dependencies?
O3 detects GHSA-ppwv-mvqg-q89h across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
