AI Analysis
Technical Summary
CVE-2026-70433 is a vulnerability in Jenkins HCL AppScan Plugin (<=1.8.3) caused by missing permission checks. Attackers with Overall/Read permission can enumerate credential IDs stored in Jenkins, potentially exposing sensitive information about stored credentials. The vulnerability is classified under CWE-862 (Missing Authorization). No official patch or remediation level has been provided yet, and no known exploits are reported in the wild.
Potential Impact
The vulnerability allows attackers with limited permissions (Overall/Read) to enumerate credential IDs, which could facilitate further attacks by revealing the existence and identifiers of stored credentials. However, it does not allow direct credential access, modification, or denial of service. The impact is limited to information disclosure of credential identifiers only.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Overall/Read permissions to trusted users only to reduce the risk of credential ID enumeration.
