CVE-2026-42016: 
Artifactory vulnerability analysis and mitigation

CVE-2026-42016 is a privilege escalation vulnerability in JFrog Artifactory (Self-Hosted) affecting all versions before 7.133.11. The flaw arises because the token validation logic checks the token's signature and issuer but fails to validate the token's scope, allowing authenticated users to escalate their privileges beyond their intended permissions. It was published on July 27, 2026, and assigned by JFrog as a CVE Numbering Authority (CNA). The vulnerability carries a CVSS v3.1 base score of 8.8 (High) per NVD, or 8.1 (High) per the ENISA/EUVD scoring (Feedly, JFrog Advisory).

The root cause is classified as CWE-863 (Incorrect Authorization). The Artifactory access token validation mechanism verifies the token's cryptographic signature and issuer identity but neglects to enforce the token's declared scope, meaning a token issued with limited permissions can be used to perform actions outside its intended authorization boundary. This is a network-accessible vulnerability (attack vector: network) requiring only low-level authenticated access, with no user interaction needed. No public technical write-up or proof-of-concept code has been identified at this time (Feedly).

Any authenticated user with valid credentials can exploit this vulnerability to escalate their privileges, gaining access to resources and performing actions they are not authorized to perform within the Artifactory instance. This affects confidentiality, integrity, and availability — a successful attacker could read sensitive artifacts, modify repository contents, or disrupt service operations. In environments where Artifactory serves as a central artifact repository for CI/CD pipelines, exploitation could enable supply chain attacks or lateral movement into downstream build and deployment systems (Feedly).

As of the time of publication, there is no public proof-of-concept exploit and no evidence of in-the-wild exploitation. The NVD SSVC assessment classifies exploitation as "none" and technical impact as "partial." The EPSS score is approximately 0.209%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Feedly).

JFrog has released a patch in Artifactory Self-Hosted version 7.133.11, which corrects the token validation logic to include scope enforcement. Organizations should upgrade to version 7.133.11 or later as the primary remediation step. Additionally, JFrog recommends reviewing and auditing token usage and user permissions to identify any unauthorized access that may have occurred prior to patching, and implementing monitoring for privilege escalation attempts and token misuse. Note that JFrog Cloud (SaaS) deployments are not affected by this vulnerability (JFrog Advisory, Feedly).

The vulnerability received limited public attention shortly after disclosure, with automated aggregation on platforms such as VulDB, CVEFeed, and Vulners. A brief mention appeared on Bluesky via the CyberHub blog. No significant researcher commentary, vendor statements beyond the advisory, or major media coverage has been identified (Feedly).
