Impact
The malicious user is able to discover services in the internal network through repository migration functionality. All installations accepting public traffic are affected.
Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.
GHSA-Q347-CG56-PCQ4 has a CVSS score of 5.0 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.12.5); upgrading removes the vulnerable code path.

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.

Internal network CIDRs are prohibited to be used as repository migration targets. Users should upgrade to 0.12.5 or the latest 0.13.0+dev.
Frequently Asked Questions
- What is GHSA-Q347-CG56-PCQ4? GHSA-Q347-CG56-PCQ4 is a medium-severity server-side request forgery (SSRF) vulnerability in gogs.io/gogs (go), affecting versions < 0.12.5. It is fixed in 0.12.5. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
- How severe is GHSA-Q347-CG56-PCQ4? GHSA-Q347-CG56-PCQ4 has a CVSS score of 5.0 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of gogs.io/gogs are affected by GHSA-Q347-CG56-PCQ4? gogs.io/gogs (go) versions < 0.12.5 is affected.
- Is there a fix for GHSA-Q347-CG56-PCQ4? Yes. GHSA-Q347-CG56-PCQ4 is fixed in 0.12.5. Upgrade to this version or later.
- Is GHSA-Q347-CG56-PCQ4 exploitable, and should I be worried? Whether GHSA-Q347-CG56-PCQ4 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 GHSA-Q347-CG56-PCQ4 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 GHSA-Q347-CG56-PCQ4? Upgrade
gogs.io/gogsto 0.12.5 or later.
