Description
Jenkins Contrast Continuous Application Security Plugin 3.11 and earlier does not perform a permission check in an HTTP endpoint that tests the connection to a Contrast TeamServer.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using an attacker-specified username, API key, and service key.
Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Contrast Continuous Application Security Plugin 3.12 requires Overall/Administer permission and POST requests to test the connection to a Contrast TeamServer.

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:contrast-continuous-application-security, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:contrast-continuous-application-security to 3.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-57298 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.
