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 JFrog Artifactory self-managed versions 7.161.0 through 7.161.11 and versions prior to 7.146.29 (in the 7.146.x branch). The vulnerability was published on August 25, 2026, and patched versions were released the same day. It carries 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 (JFrog Advisory, Github Advisory). The attack vector is network-based, requires low privileges (a valid authenticated account), no user interaction, and low attack complexity. No public proof-of-concept or detailed technical write-up describing the specific triggering conditions has been disclosed.

Successful exploitation is limited to a confidentiality impact — an authenticated low-privileged user could read package metadata (e.g., package names, versions, dependencies) from Composer repositories they are not authorized to access. There is no integrity or availability impact. While the exposed data is metadata rather than package content itself, unauthorized visibility into private repository metadata could facilitate reconnaissance, supply chain mapping, or targeted attacks against internal software dependencies (JFrog Advisory, Github Advisory).

There is no evidence of active in-the-wild exploitation, and no public proof-of-concept exploit has been identified (Github Advisory). 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. NVD SSVC assessment classifies exploitation as 'none' and the technical impact as 'partial' (JFrog Advisory).

JFrog has released patched versions addressing this vulnerability. Self-managed users should upgrade to Artifactory 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 patched and require no action. No specific configuration-based workaround has been published for this CVE; upgrading to a fixed version is the recommended remediation (JFrog Advisory, Artifactory Releases).
