CVE-2026-57291 describes a security flaw in the Jenkins Gitee Plugin where missing permission checks permit attackers who have Overall/Read access to cause the plugin to connect to arbitrary URLs specified by the attacker. The attacker can use credentials IDs they have obtained through other methods, potentially enabling unauthorized interactions with external systems. No CVSS score or detailed vendor remediation information is currently available.

Attackers with Overall/Read permission can misuse the plugin to connect to attacker-controlled URLs using credentials IDs they have acquired elsewhere. This could lead to unauthorized data exposure or interaction with external systems under the context of the Jenkins environment. The exact impact depends on the attacker's ability to obtain valid credentials IDs and the nature of the external systems targeted.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Overall/Read permissions to trusted users only and monitor for unusual plugin activity. Avoid exposing credentials IDs unnecessarily and review plugin usage policies.
