JFrog Artifactory Privilege Escalation and Admin Access Vulnerability (CVE-2026-42016) Advisory

• Immediate Upgrade: Apply the 7.133.11 patch or later immediately. 2. Token Revocation: Identify and revoke any access tokens created or used for unauthorized administrative actions during the potential window of exploitation. 3. Network Hardening: Restrict access to the Artifactory management console and sensitive API endpoints (e.g., /api/access/*) to trusted internal networks only using a WAF or firewall.

This vulnerability (CWE-863) stems from a critical flaw in the token validation mechanism of JFrog Artifactory. While the application correctly verifies the cryptographic signature and the issuer of an access token, it fails to validate the 'scope' attribute. This oversight allows an attacker with a valid, low-privilege token to bypass authorization checks and perform administrative actions. Given its inclusion in the CISA KEV catalog and an EPSS score of 0.94, this vulnerability is being actively exploited in the wild and poses a severe risk to DevSecOps pipelines.
