Summary
Gogs allows users to write to readonly repositories using receive-pack + service=git-upload-pack confusion
Impact
If you can read a repository, and an anonymous user cannot, you can write to it. This affects some cases where read-only collaborator access is given, but is most impactful in instances with REQUIRE_SIGNIN_VIEW = true configured, because then all repositories will be writable to any user.
Using force push this can also affect availability, as the original code in the main branch, for example, can be overridden without leaving history.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-52810? CVE-2026-52810 is a high-severity security vulnerability in gogs.io/gogs (go), affecting versions < 0.14.3. It is fixed in 0.14.3.
- Which versions of gogs.io/gogs are affected by CVE-2026-52810? gogs.io/gogs (go) versions < 0.14.3 is affected.
- Is there a fix for CVE-2026-52810? Yes. CVE-2026-52810 is fixed in 0.14.3. Upgrade to this version or later.
- Is CVE-2026-52810 exploitable, and should I be worried? Whether CVE-2026-52810 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-52810 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-52810? Upgrade
