CVE-2026-92140 Jenkins Project CVE debrief

Who should care

Defenders responsible for Jenkins instances with the Gitee Plugin should assess exposure and risk of malicious script injection. Security teams should verify version information and implement compensating controls to detect and prevent XSS attacks.

Why it matters

CVE-2026-92140 is a stored XSS vulnerability in Jenkins Gitee Plugin versions 1301.v8957053c7902 and earlier, allowing attackers to inject malicious scripts into build causes via Gitee push webhook payloads. Defenders should prioritize verifying exposure and assessing risk.

• Defenders must verify Jenkins instance exposure and Gitee Plugin version to determine potential vulnerability.
• Security teams should assess the risk of malicious script injection via Gitee push webhook payloads.
• Compensating controls should be implemented to detect and prevent XSS attacks.

Technical summary

The Jenkins Gitee Plugin versions 1301.v8957053c7902 and earlier do not escape the sender name from Gitee push webhook payloads in build causes, resulting in a stored cross-site scripting (XSS) vulnerability. Attackers able to trigger builds via the Jenkins Gitee Plugin webhook endpoint can exploit this vulnerability. This vulnerability has a CVSS score of 6.8 and a severity of MEDIUM. Defenders should prioritize verifying exposure of Jenkins instances with the Gitee Plugin and assessing the risk of malicious script injection.

Defensive priority

Defenders should prioritize verifying exposure of Jenkins instances with the Gitee Plugin and assessing the risk of malicious script injection.

Recommended defensive actions

• Verify Jenkins instance exposure and Gitee Plugin version
• Assess risk of malicious script injection via Gitee push webhook payloads
• Implement compensating controls to detect and prevent XSS attacks
• Review relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
