Description
A vulnerability was found in Cockpit versions up to 2.11.3. This issue affects some unknown processing instances of the file /system/users/save. The manipulation of the arguments "name" or "email" leads to cross-site scripting. The attack may be initiated remotely. Upgrading to version 2.11.4 will address this issue. It is recommended to upgrade the affected component. The vendor was contacted early about this disclosure and acted accordingly. A patch and new release were made available very quickly.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cockpit-hq/cockpit. 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.
Fix
Update cockpit-hq/cockpit to 2.11.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j4rj-fgcq-wmqp is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-j4rj-fgcq-wmqp 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-j4rj-fgcq-wmqp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
