CVE-2025-8110: File overwrite in file update API in Gogs

Noroxi assessment

Priority: Now (action score 90/100)

  • CISA has confirmed exploitation in the wild (Jan 12, 2026). Remediation deadline for US federal agencies: Feb 2, 2026.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 85.2% (FIRST EPSS); higher than 99.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Patch today or shut off access. See the fix and affected versions sections below.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jan 12, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Feb 2, 2026.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

Fixed

ts
const file = path.resolve(ROOT, req.query.name);if (!file.startsWith(ROOT + path.sep)) {  return res.sendStatus(400);}res.sendFile(file);
