CVE-2026-70550: 
Artifactory vulnerability analysis and mitigation

CVE-2026-70550 is a missing authorization vulnerability in JFrog Artifactory's Composer repository handling that may allow an authenticated user, under specific conditions, to read package metadata from repositories they are not authorized to access. It affects Artifactory versions 7.161.0 through 7.161.11 and versions 7.146.0 through 7.146.29 (self-managed). The vulnerability was published on August 25, 2026, and has a CVSS v3.1 base score of 6.5 (Medium) (JFrog Advisory, Github Advisory).

The root cause is classified as CWE-862 (Missing Authorization) — the Composer repository handling logic in Artifactory fails to enforce proper authorization checks when an authenticated user requests package metadata, allowing access to repositories outside their permitted scope under specific conditions. The attack vector is network-based, requires low privileges (valid authentication), no user interaction, and low attack complexity. No public technical write-ups or proof-of-concept code have been identified at this time (JFrog Advisory, Github Advisory).

Successful exploitation is limited to a confidentiality impact — an authenticated low-privileged user could read package metadata from Composer repositories they are not authorized to access, potentially exposing sensitive dependency information, internal package names, or version details. There is no impact on integrity or availability. The scope is unchanged, meaning the vulnerability does not enable lateral movement beyond the Artifactory instance itself (JFrog Advisory, Github Advisory).

There is no evidence of public proof-of-concept exploit code or active in-the-wild exploitation at this time. The EPSS score is approximately 0.209% (11th percentile), indicating a low near-term exploitation probability. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no threat actor attribution has been reported (Github Advisory, JFrog Advisory).

JFrog has released patched versions addressing this vulnerability. Self-managed users should upgrade to 7.161.19 (for the 7.161.x branch) or 7.146.36 (for the 7.146.x branch). JFrog Cloud environments have already been automatically remediated and require no action. As an interim measure, administrators should audit and restrict authenticated user access to Composer repositories and monitor repository access logs for anomalous metadata read activity (JFrog Advisory, Artifactory Releases).
