DescriptionCVE.org

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.

AnalysisAI

Gitea's OpenID URI visibility controls lack proper ownership validation, allowing authenticated users to modify the visibility settings of other users' OpenID identities. This integrity bypass affects any Gitea instance where multiple users manage OpenID configurations, enabling account enumeration or information disclosure through unauthorized visibility changes. A patch is available to remediate this medium-severity vulnerability.

Technical ContextAI

Classified as CWE-284 (Improper Access Control). Affects Gitea. 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.

RemediationAI

A vendor patch is available — apply it immediately. Restrict network access to the affected service where possible.
