Core Rule Set: gitea and Forgejo file and branch names in bodies pass (closes #346)
check / check (push) Waiting to run
Details

Browse Source 
While SWW_WAF_BODY_LIMIT is set, these body fields skip only the rules
that refused them, on their own paths:

- the web editor's tree_path, commit_summary and content;
- new_branch_name of a branch created on the web or the API;
- from and to of a renamed branch, on gitea's and Forgejo's paths;
- head of a pull request and message of a file, through the API.

None applies when the query has a parameter of the same name. The
requests were recorded from gitea 1.27.3 and Forgejo 17.0.1.
