Exploitation Status

Proof-of-concept exploit code exists

  • CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
  • A successful exploit gives an attacker total control of the affected component, not partial access.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

Impact

When the built-in SSH server is enabled ([server] START_SSH_SERVER = true), unprivileged user accounts with at least one SSH key can execute arbitrary commands on the Gogs instance with the privileges of the user specified by RUN_USER in the configuration. It allows attackers to access and alter any users' code hosted on the same instance.

Patches

The env command sent to the internal SSH server has been changed to be a passthrough (https://github.com/gogs/gogs/pull/7868), i.e. the feature is effectively removed. Users should upgrade to 0.13.1 or the latest 0.14.0+dev.

Workarounds

Disable the use of built-in SSH server on operating systems other than Windows.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gogs.io/gogs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update gogs.io/gogs to 0.13.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vm62-9jw3-c8w3 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
