Description
Jenkins 2.567 and earlier, LTS 2.555.2 and earlier does not ensure that the "from" parameter in the "Delegate to servlet container" security realm is safe to redirect to after login, allowing attackers to perform phishing attacks by redirecting users to an attacker-controlled domain.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.main:jenkins-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.main:jenkins-core to 2.555.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-92m7-4fpw-2wxm is resolved across your whole dependency graph.
Workarounds
Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
The CVE is rated Moderate (4.3), but the impact on Red Hat products is Low. The Jenkins RPM shipped in ocp-tools includes the vulnerable "Delegate to servlet container" security realm code, but the OpenShift Jenkins image uses the OpenShift Login plugin for authentication by default. The servlet container realm is…
Verify which security realm your Jenkins instance uses under Manage Jenkins > Security. If it is set to anything other than "Delegate to servlet container" your instance is not affected. If you are using servlet container delegation, switch to one of the other available security realms.Source: Red Hat security advisory for GHSA-92m7-4fpw-2wxm (CC BY 4.0)
