Security readout for executives and security teams
CVE-2023-25763 is a stored XSS issue in Jenkins Email Extension Plugin 2.93 and earlier. If an authenticated attacker can control affected fields, malicious content may be stored and later rendered in bundled email templates when a user views the email content. Exposure is most likely on Jenkins controllers using Email Extension Plugin 2.93 or earlier, especially where lower-privileged users can influence build, job, or notification fields rendered into bundled templates. Treat this as a moderate-priority Jenkins hygiene issue. It is not described as actively exploited, but it can affect trusted engineering workflows and should be remediated during normal vulnerability patch cycles. Mitigation focus: Inventory Jenkins instances using Email Extension Plugin.; Check plugin versions and prioritize 2.93 or earlier.; Review Jenkins vendor advisory for the fixed release guidance..
