Q1What is this vulnerability? (Essence + Consequences)
🚨 **Root Cause**: When Gitea switches the visibility of OpenID URIs, it **fails to properly verify ownership**.
💥 **Impact**: Authenticated users can **tamper with the OpenID visibility settings** of other users.
Q2Root Cause? (CWE/Flaw)
🔍 **Vulnerability Point**: Missing logical validation.
📉 **CWE Tendency**: Broken Access Control (Lack of ownership check).
⚠️ **Core Issue**: The system allows users to modify the visibility status of OpenID URIs that t…
📦 **Component**: Gitea (a lightweight Git service developed in Go).
📅 **Affected Versions**: All versions prior to v1.25.4.
✅ **Fixed Version**: v1.25.4.
Q4What can hackers do? (Privileges/Data)
🕵️ **Attacker Capabilities**:
1. **Privacy Leakage**: Forcefully change other users' OpenID visibility (e.g., from private to public).
2.…
🔑 **Difficulty**: **Low**.
✅ **Prerequisite**: Only requires a standard **authenticated** user account.
⛔ **Not Required**: Administrator privileges or remote code execution vulnerabilities.
Q6Is there a public Exp? (PoC/Wild Exploitation)
📜 **Exp/PoC**:
🚫 **No Public PoC**: The `pocs` field is empty in the data.
🌍 **In-the-Wild Exploitation**: No reports available.
🔗 **Fixing PRs**: #36361 and #36346 have been merged.
Q7How to self-check? (Features/Scanning)
🔎 **Self-Check Method**:
1. **Check Version**: Confirm if the Gitea version is < v1.25.4.
2. **Review Logs**: Check for any operations modifying OpenID URI visibility where the user is not the owner.
3.…
🛡️ **Officially Fixed**:
✅ **Patch**: **Gitea v1.25.4** has been released.
📝 **Details**: See GitHub Security Advisory (GHSA-jrpc-w85r-hgqx) and the official blog.
Q9What if no patch? (Workaround)
🚧 **Temporary Mitigation**:
1. **Upgrade**: Immediately upgrade to v1.25.4 or later.
2. **Restrict Permissions**: Limit the ability of regular users to modify OpenID settings (if supported by the UI).
3.…
⚡ **Priority**: **Medium-High**.
📌 **Reason**: Involves **privacy leakage** and **unauthorized operations**, with a low exploitation threshold (requires only login).…
