EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 62% 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. Prior to 0.14.3, three API endpoints — PATCH /api/v1/repos/:owner/:repo/issue-tracker, PATCH /api/v1/repos/:owner/:repo/wiki, and POST /api/v1/repos/:owner/:repo/mirror-sync — are gated by reqRepoWriter() rather than reqRepoAdmin(). The equivalent operations in the web UI sit behind reqRepoAdmin, which requires AccessMode >= AccessModeAdmin. A write-level collaborator (who has AccessMode == AccessModeWrite < AccessModeAdmin) can therefore call these API endpoints directly to disable the native issue tracker or wiki, inject attacker-controlled external tracker/wiki URLs that redirect all repository visitors, or trigger mirror sync — none of which they are authorized to do. This vulnerability is fixed in 0.14.3.
