GHSA-pfvh-p8qp-9ww9 is a critical-severity (CVSS 9.8) OS Command Injection vulnerability in gogs.io/gogs. 1 public exploit or proof-of-concept reference is indexed, so weaponization risk is real. A fix is available for gogs.io/gogs — see the affected versions and patch details below.
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.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Where this sits among everything scored
Real-World Exposure
gogs.io/gogsReal-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
The malicious user is able to update a crafted config file into repository's .git directory in combination with crafted file deletion to gain SSH access to the server on case-insensitive file systems. All installations with repository upload enabled (default) on case-insensitive file systems (Windows, macOS, etc.) are affected.
Patches
Make sanitization of upload path to .git directory to be case-insensitive. Users should upgrade to 0.12.11 or the latest 0.13.0+dev.
Workarounds
Disable repository upload.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update gogs.io/gogs to 0.12.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pfvh-p8qp-9ww9 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
