CVE-2025-64719
MEDIUMCVE-2025-64719 is a medium-severity (CVSS 4.9) Improper Input Validation vulnerability in gogs.io/gogs. O3 Security confirms whether CVE-2025-64719 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Gogs: Denial of Service in repository/wiki file listing web pages
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
Gogs is an open source self-hosted Git service. Prior to 0.14.3, a malicious user with rights to create a new file on a repository or wiki page can trigger a denial of service condition in which the pages containing the listing of files will return HTTP error 500 and render the web interface unusable for the repository or wiki. The issue is present in file internal/route/repo/wiki.go and internal/route/repo/view.go where the pages try to recover commit information. If errors are returned while recovering commit information, the page will return a 500 error and stop rendering, resulting in a denial of service. This vulnerability is fixed in 0.14.3.
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 0.14.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-64719 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-2025-64719 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-2025-64719. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
