Operationally, ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a missing permission check, tracked as CWE-862, in the Jenkins Git Plugin 4.11.3 and earlier. It affects Jenkins jobs that rely on this plugin for Git-based source code management and carries a CVSS 3.1 base score of 7.5 reflecting network-exploitable integrity impact without authentication.
Unauthenticated attackers can exploit the flaw to trigger builds of jobs that use an attacker-specified Git repository and to force checkout of an attacker-chosen commit, enabling unauthorized modification of build artifacts or execution of attacker-controlled code within the build environment.
The Jenkins security advisory and associated Openwall disclosure provide the authoritative details on affected versions and remediation steps. The EPSS score has reached a peak of 0.8677 with a current value of 0.8079, indicating sustained exploitation interest after public disclosure.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
