Detailsinfo

A vulnerability was found in Gitea up to 28.3.x. It has been rated as problematic. This issue affects an unknown functionality of the component Repository Initialization. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. Impacted is integrity, and availability. The summary by CVE is:

A repository created with auto-init accepted pushes before its initialization had finished, and the initial commit was built in a checkout of whatever the repository already contained. A user who is allowed to create repositories could push a crafted tree during that window so that writing the README followed a symbolic link and overwrote a server-side git hook, which runs commands as the Gitea system user. The initial commit is now built in a freshly initialized directory, and a new repository only becomes ready, and accepts pushes, once its initialization is complete.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-125423 since 11/15/2026. The exploitation is known to be easy. The attack may be initiated remotely. The technical details are unknown and an exploit is not publicly available.
