EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 94% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Gogs is an open source self-hosted Git service. In 0.14.3 and earlier, any authenticated user can watch a private repository they have no access to, because the access check in the Watch API handler is inverted. The code checks if repoCtx.ViewerCanRead() (returns 404 when the user CAN read) instead of if !repoCtx.ViewerCanRead() (return 404 when the user CANNOT read). Once watching, the attacker's dashboard activity feed shows commit messages, branch names, issue titles, and PR details from the private repository. If email notifications are enabled, the attacker also receives emails containing issue and comment content.
