GHSA-q2mm-w3qc-2936
MEDIUMGHSA-q2mm-w3qc-2936 is a medium-severity (CVSS 6.4) Cross-site Scripting (XSS) vulnerability in org.jenkins-ci.plugins:link-column. O3 Security confirms whether GHSA-q2mm-w3qc-2936 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Stored XSS vulnerability in Jenkins Link Column Plugin
Blast Radius
org.jenkins-ci.plugins:link-columnReal-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
Link Column Plugin allows users with View/Configure permission to add a new column to list views that contain a user-configurable link.\n\nLink Column Plugin 1.0 and earlier does not filter the URL for these links, allowing the javascript: scheme. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users able to configure list views.

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:link-column. 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:link-column has shipped for GHSA-q2mm-w3qc-2936 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-q2mm-w3qc-2936 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-q2mm-w3qc-2936. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
