HIGHPre-NVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 68% 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, a Server-Side Request Forgery (SSRF) vulnerability exists in the repository migration functionality. The application validates only the initially submitted URL hostname, but git clone --mirror follows HTTP redirects. An authenticated user can submit a public URL that redirects to a blocked internal endpoint (e.g., 127.0.0.1), importing the internal repository's contents into an attacker-controlled repository. This vulnerability is fixed in 0.14.3.
