DescriptionCVE.org

An unauthenticated user may access restricted repository information under specific conditions.

AnalysisAI

Unauthorized repository information disclosure in JFrog Artifactory allows unauthenticated remote users to read restricted repository content under specific deployment conditions. Rooted in CWE-862 (Missing Authorization), the flaw bypasses access controls without credentials, confirmed by a PR:N/AV:N CVSS vector. No public exploit code and no CISA KEV listing exist at time of analysis, and the 'specific conditions' qualifier in the vendor's own description limits the realistic attack surface compared to the raw CVSS score suggests.

Technical ContextAI

JFrog Artifactory (CPE: cpe:2.3:a:jfrog:artifactory:*:*:*:*:*:*:*:*) is a universal binary artifact repository manager central to enterprise CI/CD pipelines, storing packages across formats including Maven, Docker, npm, PyPI, and Helm. The root cause is CWE-862 (Missing Authorization): a code path exists that serves repository metadata or content without performing the expected authorization check, meaning the system never validates whether the requesting identity has read permissions on the target repository. The wildcard version in the CPE string indicates the vulnerability spans an unspecified range of Artifactory releases; exact affected versions are not enumerated in the available intelligence.

RemediationAI

The primary remediation is to apply the vendor-released patch by upgrading Artifactory to a fixed version as directed by the JFrog security advisory at https://docs.jfrog.com/releases/docs/jfrog-security-advisories; the exact fix version is not confirmed in the available data, so consult the self-managed release notes at https://docs.jfrog.com/releases/docs/artifactory-self-managed-releases to identify the first patched build. As a compensating control pending upgrade, restrict network access to Artifactory's HTTP/HTTPS ports to trusted IP ranges or authenticated proxies - this directly limits unauthenticated access regardless of the underlying code path. Additionally, audit Artifactory repository permissions to ensure no repositories are misconfigured as publicly accessible when they should not be, since proper permission configuration may independently prevent exploitation under the 'specific conditions' referenced in the description. Note that network-layer restrictions may impact legitimate external consumers of the registry.
