CVE-2026-57293 in Gitee Plugin
Summary
by MITRE • 06/24/2026
An incorrect permission check in Jenkins Gitee Plugin 1288.v18b_deb_c9069b_ and earlier allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate credentials IDs of credentials stored in Jenkins.

The vulnerability resides within the Jenkins Gitee Plugin version 1288.v18b_deb_c9069b and earlier, where an improper permission validation mechanism exists that enables unauthorized credential enumeration. This flaw specifically affects systems where attackers possess global Item/Configure permission but lack targeted Item/Configure access to individual jobs. The vulnerability stems from insufficient authorization checks during credential retrieval operations, allowing malicious actors to discover credential identifiers stored within the Jenkins instance despite not having direct permissions to configure specific jobs.
This security weakness represents a privilege escalation issue that violates fundamental access control principles and aligns with CWE-284, which addresses improper access control mechanisms. The flaw operates by bypassing the normal permission validation flow that should restrict credential enumeration to only those users who have explicit authorization to access specific job configurations. Attackers can exploit this vulnerability to gather information about available credentials without needing the granular permissions required for actual credential usage.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with valuable reconnaissance data that could facilitate subsequent attacks. Credential ID enumeration enables threat actors to identify which credentials are available within the Jenkins environment, potentially revealing sensitive authentication mechanisms such as API tokens, SSH keys, or password-based credentials. This information can then be used to craft targeted attacks against specific credential stores or to bypass additional security controls by understanding what authentication mechanisms exist.
The vulnerability presents a significant risk in environments where Jenkins serves as a central automation hub for continuous integration and deployment processes, particularly when multiple teams share the same instance with varying permission levels. Organizations implementing this plugin without proper access controls may inadvertently expose their credential infrastructure to unauthorized enumeration. The flaw demonstrates how insufficient permission validation can create information leakage channels that provide attackers with strategic advantages in planning more sophisticated attacks.
Mitigation strategies should focus on implementing proper authorization checks that enforce granular permissions for credential access operations. Organizations should upgrade to the latest version of the Jenkins Gitee Plugin where this vulnerability has been resolved, and implement comprehensive monitoring for unauthorized credential enumeration attempts. Additionally, security teams should review existing permission configurations to ensure that users with global Item/Configure permissions do not inadvertently gain access to credential information beyond their intended scope. The remediation approach should align with NIST SP 800-53 access control requirements and follow ATT&CK technique T1212 for credential access, emphasizing the need for proper authorization enforcement throughout the system architecture.
