No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The git hook feature in Gogs 0.5.5 through 0.12.2 allows for authenticated remote code execution. There can be a privilege escalation if access to this hook feature is granted to a user who does not have administrative privileges. NOTE: because this is mentioned in the documentation but not in the UI, it could be considered a "Product UI does not Warn User of Unsafe Actions" issue.

Exploitation public PoC (EG-KEV: weaponized) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.

Publicly available exploits

(2 references)

Working exploit code is in the public domain (1 Metasploit module). Defenders should treat patch urgency accordingly — public PoCs typically lead to mass-exploitation within 24-72 hours.
