Technical details

A vulnerability in the 'SaveAddress' function within Gogs Mirror Settings allows for a validation bypass. While the initial 'New Migration' workflow correctly validates repository URLs, the update path for existing mirrors fails to enforce the same checks, such as protocol whitelisting and local network address blocking. An authenticated attacker can exploit this by first creating a legitimate mirror and then updating the address to use the 'file://' protocol to read local repositories or internal network addresses (SSRF). This issue is classified as improper input validation (CWE-20) and is resolved in version 0.14.3 by unifying the validation logic across both creation and update paths.
