CVE-2026-89094Network attack vector

Remote code execution via template-created Git directory

Published Sep 10, 2026 · Updated Sep 10, 2026

Remote code execution in Forgejo before 15.0.8 and 16.0.0 through 16.0.3 allows remote authenticated users to run host processes. Template expansion can create a new .git directory that Git adopts during repository initialization, including attacker-controlled configuration. Exploitation requires permission to create and instantiate a template repository and enables host-file reads and process execution under the Forgejo service account.
