CVE-2026-52806 — Gogs: RCE via git rebase --exec argument injection in pull request merge

Gogs is an open source self-hosted Git service. Prior to 0.14.3, Gogs allows authenticated users to achieve Remote Code Execution (RCE) on the server by creating a pull request with a specially crafted branch name that injects the --exec flag into the git rebase command during the "Rebase before merging" merge operation. This vulnerability is fixed in 0.14.3.

Remediation

The vendor's own words where we have them.

Upgrade gogs to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.

First 24 hours

Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.

  • Identify exposed assets running affected vendor/product/version combinations.
  • Prioritize based on EPSS, PoC availability, and external exposure.
  • Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

What this weakness leads to

MITRE's own consequences and mitigations for the weakness class — the authority's wording, not guidance derived from the CVSS vector.

MITRE

CWE-77 · Improper Neutralization of Special Elements used in a Command ('Command Injection')

  • Execute Unauthorized Code or Commands

Mitigation: If at all possible, use library calls rather than external processes to recreate the desired functionality.

What should defenders know first?

CVE-2026-52806 is Gogs: RCE via git rebase --exec argument injection in pull request merge, a critical vulnerability affecting gogs from gogs. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-52806. Public exploit evidence is: 2 public PoC repositories reported; 1 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 9.9 describes technical severity, while EPSS 8% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
