gitea vulnerabilities

Gitea does not properly validate ownership when toggling OpenID URI visibility. An authenticated user may be able to change the visibility settings of other users' OpenID identities.

Gitea does not properly verify authorization when canceling scheduled auto-merges via the web interface. A user with read access to pull requests may be able to cancel auto-merges scheduled by other users.

Gitea's stopwatch API does not re-validate repository access permissions. After a user's access to a private repository is revoked, they may still view issue titles and repository names through previously started stopwatches.

Gitea's notification API does not re-validate repository access permissions when returning notification details. After a user's access to a private repository is revoked, they may still view issue and pull request titles through previously received notifications.

In Gitea before 1.25.2, /api/v1/user has different responses for failed authentication depending on whether a username exists.

In Gitea before 1.20.1, a forbidden URL scheme such as javascript: can be used for a link, aka XSS.

In Gitea before 1.21.2, an anonymous user can visit a private user's project.

Gitea before 1.22.2 sometimes mishandles the propagation of token scope for access control within one of its own package registries.

Gitea before 1.21.8 inadvertently discloses users' login times by allowing (for example) the lastlogintime explore/users sort order.

Gitea before 1.22.2 allows XSS because the search input box (for creating tags and branches) is v-html instead of v-text.

Gitea before 1.22.3 mishandles access to a private resource upon receiving an API token with scope limited to public resources.

Gitea before 1.25.2 mishandles authorization for deletion of releases.

In Gitea through 1.17.1, repo cloning can occur in the migration function.

Open Redirect in GitHub repository go-gitea/gitea prior to 1.19.4.

In Jenkins Gitea Plugin 1.4.4 and earlier, the implementation of Gitea personal access tokens did not support credentials masking, potentially exposing them through the build log.

In Gitea before 1.16.9, it was possible for users to add existing issues to projects. Due to improper access controls, an attacker could assign any issue to any project in Gitea (there was no permission check for fetching the issue). As a result, the attacker would get access to private issue titles.

Cross-site Scripting (XSS) - Stored in GitHub repository go-gitea/gitea prior to 1.16.9.

Open Redirect on login in GitHub repository go-gitea/gitea prior to 1.16.5.

The avatar middleware in Gitea before 1.13.6 allows Directory Traversal via a crafted URL.

Cross Site Scripting (XSS) vulnerability exists in Gitea before 1.5.1 via the repository settings inside the external wiki/issue tracker URL field.

Gitea before 1.4.3 is affected by URL Redirection to Untrusted Site ('Open Redirect') via internal URLs.

Gitea 1.7.0 and earlier is affected by: Cross Site Scripting (XSS). The impact is: Attacker is able to have victim execute arbitrary JS in browser. The component is: go-get URL generation - PR to fix: https://github.com/go-gitea/gitea/pull/5905. The attack vector is: victim must open a specifically crafted URL. The fixed version is: 1.7.1 and later.

Gitea 1.7.2, 1.7.3 is affected by: Cross Site Scripting (XSS). The impact is: execute JavaScript in victim's browser, when the vulnerable repo page is loaded. The component is: repository's description. The attack vector is: victim must navigate to public and affected repo page.

Gitea version 1.6.2 and earlier contains a Incorrect Access Control vulnerability in Delete/Edit file functionallity that can result in the attacker deleting files outside the repository he/she has access to. This attack appears to be exploitable via the attacker must get write access to "any" repository including self-created ones.. This vulnerability appears to have been fixed in 1.6.3, 1.7.0-rc2.
