CVE-2026-70443: Vulnerability in Jenkins Project Jenkins Horreum Plugin
Jenkins Horreum Plugin 0.16.162.v33b_4a_a_b_5f828 and earlier does not set the appropriate context for credentials lookup, allowing attackers with Item/Configure permission to have Jenkins send credentials they are not entitled to use to the administrator-configured Horreum URL.
AI Analysis
Technical Summary
The Jenkins Horreum Plugin up to version 0.16.162.v33b_4a_a_b_5f828 contains a flaw where the credentials lookup context is improperly set. This enables users who have Item/Configure permissions to trigger Jenkins to send credentials beyond their entitlement to the administrator-configured Horreum URL. The vulnerability could lead to unauthorized disclosure of credentials within Jenkins environments using this plugin.
Potential Impact
Attackers with Item/Configure permission can cause Jenkins to disclose credentials they should not have access to, potentially exposing sensitive authentication material to the Horreum URL. This could lead to unauthorized access or further compromise depending on the credentials exposed. However, exploitation requires the attacker to already have Item/Configure permissions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Item/Configure permissions to trusted users only and monitor for unusual credential usage related to the Horreum Plugin.
