JFrog Artifactory Vulnerability CVE-2026-42016 Added to CISA KEV List

## Overview CISA added CVE-2026-42016 to its Known Exploited Vulnerabilities (KEV) list on September 11, 2026. This vulnerability affects JFrog Artifactory (Self Hosted) versions prior to 7.133.11. The addition to the KEV list indicates a federal deadline for remediation. Organizations using affected versions must act quickly to avoid potential exploitation. ## Technical Details CVE-2026-42016 is an incorrect authorization vulnerability. It arises from a failure to validate the token’s scope during the authorization process. Instead, the system only checks the token's signature and issuer. This oversight allows attackers to escalate privileges within the application, gaining unauthorized access to sensitive resources. ## Impact The CVSS score for this vulnerability is 8.8, indicating a high severity level. Successful exploitation can lead to privilege escalation, allowing attackers to perform actions beyond their intended access rights. This could result in data breaches, unauthorized changes, and severe impacts on system integrity and confidentiality. ## Mitigation Organizations should upgrade to JFrog Artifactory version 7.133.11 or later as soon as possible. Regularly review and update software to mitigate vulnerabilities. Implement additional security measures such as monitoring access logs and employing least privilege principles to limit user permissions. Failure to address this vulnerability may expose systems to significant risks.
