Gitea: Fork-PR Actions task can read a third private repository via the collaborative-owner branch (missing fork-PR guard)

Summary GetActionsUserRepoPermission models/perm/access/repopermission.go decides whether an Actions task token may access a target repo. Its cross-repo branches each enforce a fork-PR discriminator — except the collaborative-owner branch, which is missing the !task.IsForkPullRequest guard that i...

GHSA-PGQF-926R-548M Gitea: Cross-repository label-ID enumeration oracle via unscoped DeleteIssueLabel API

Summary The API endpoint DELETE /repos/owner/repo/issues/index/labels/id loads the label by ID with a global, unscoped lookup and never verifies the label belongs to the URL's repository or its owning organization. Because the response status differs by whether the label ID exists anywhere on the...

GHSA-2M9V-5Q2G-58VQ Gitea: Git LFS object reuse allows non-Code access to authorize private source objects

Summary A user with Code write access to one repository may be able to associate an existing Git LFS object from a private source repository with their target repository, even when they do not have Code access to the source repository that currently owns the LFS object. The issue appears to be...

Gitea: Cross-repository issue/comment attachment re-linking can expose private attachment content

Summary Gitea's issue and comment attachment update paths accept attachment UUIDs without verifying that each attachment belongs to the target issue/comment repository. If an authenticated attacker knows a victim attachment UUID, they can re-link that attachment to an attacker-controlled issue or...

Gitea: Cross-repository IDOR in issue-dependency removal lets an attacker tamper with and comment on private repos they cannot access

This is a cross-repository IDOR / broken access control issue. An attacker can tamper with issue-tracking state dependency relationships and inject an attacker-authored comment into a private repository they cannot otherwise read or write to, crossing a trust boundary the "add" path explicitly...
