Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-42016 is a privilege escalation vulnerability affecting JFrog Artifactory Self Hosted versions prior to 7.133.11. The flaw resides in the token validation logic, which correctly verifies the token's signature and issuer but fails to enforce the token's defined scope. This oversight allows an authenticated attacker, even with low-privileged access, to exploit a valid token to perform actions beyond their assigned permissions and escalate their privileges within an Artifactory deployment, potentially reaching administrative access. The vulnerability has been observed in active exploitation, often chained with other Artifactory flaws to bypass authentication and gain administrative control.

Description: JFrog Artifactory (Self Hosted) versions before 7.133.11 are vulnerable to a privilege escalation attack due to a validation check of the token signature/issuer and not the token’s scope.
