CVE-2024-56731 is a critical-severity (CVSS 10) CWE-552 vulnerability in gogs.io/gogs. A fix is available for gogs.io/gogs — see the affected versions and patch details below.
Gogs deletion of internal files allows remote command execution
Exploitation Status
No confirmed exploitation observed yet
- 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.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2024-56731 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
Due to the insufficient patch for the CVE-2024-39931, it's still possible to delete files under the .git directory and achieve remote command execution.
Details
In the patch for CVE-2024-39931, the following check is added: https://github.com/gogs/gogs/commit/77a4a945ae9a87f77e392e9066b560edb71b5de9
+ // 🚨 SECURITY: Prevent uploading files into the ".git" directory
+ if isRepositoryGitPath(opts.TreePath) {
+ return errors.Errorf("bad tree path %q", opts.TreePath)
+ }
While the above code snippet checks if the specified path is a .git directory, there are no checks for symbolic links in the later steps. So, by creating a symbolic link that points to the .git directory, an attacker can still delete arbitrary files in the .git directory and achieve remote command execution.
Impact
Unprivileged user accounts can execute arbitrary commands on the Gogs instance with the privileges of the account specified by RUN_USER in the configuration. It allows attackers to access and alter any users' code hosted on the same instance.

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 0.13.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56731 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-56731 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-56731. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
