MEDIUMMissing permission checks in Jenkins CONS3RT Plugin allow capturing credentials
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.
Blast Radius
org.jenkins-ci.plugins:cons3rtReal-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
CONS3RT Plugin 1.0.0 and earlier does not perform permission checks in methods implementing form validation.
This allows attackers with Overall/Read permission to connect to an attacker-specified HTTP server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
Additionally, these form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

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:cons3rt. 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:cons3rt has shipped for GHSA-74x9-fhc2-p79f 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-74x9-fhc2-p79f 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-74x9-fhc2-p79f. 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-74x9-fhc2-p79f in your dependencies?
O3 detects GHSA-74x9-fhc2-p79f across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
