CWE-59 Improper Link Resolution Before File Access ('Link Following')
Fix
1.25.5
Upgrade code.gitea.io/gitea to this version or later

Description

Gitea versions before 1.25.5 mishandle path resolution during template repository generation, allowing template processing to read or write through symlinked or otherwise non-regular paths.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

go get code.gitea.io/gitea@v1.25.5 && go mod tidy

Weakness

CWE-59: Improper Link Resolution Before File Access ('Link Following')

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

How to prevent it
  • Architecture and Design: Follow the principle of least privilege when assigning access rights to entities in a software system. Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
