CVE-2022-1884
CRITICALCVE-2022-1884 is a critical-severity (CVSS 10) OS Command Injection vulnerability in gogs.io/gogs. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2022-1884 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Remote Command Execution in gogs/gogs
Blast Radius
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
A remote command execution vulnerability exists in gogs/gogs versions <=0.12.7 when deployed on a Windows server. The vulnerability arises due to improper validation of the tree_path parameter during file uploads. An attacker can set tree_path=.git. to upload a file into the .git directory, allowing them to write or rewrite the .git/config file. If the core.sshCommand is set, this can lead to remote command execution.
Affected Packages

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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update gogs.io/gogs to 0.12.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-1884 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 pinpoints whether CVE-2022-1884 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2022-1884. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
