Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Gogs < 0.14.2 suffers from **Data Forgery** (CWE-345). LFS objects from different repos can be overwritten. π₯ **Consequences**: Leads to **Supply Chain Attacks**.β¦
π‘οΈ **Root Cause**: **CWE-345** (Potential Code Injection/Data Forgery). The flaw lies in how LFS objects are handled across repositories, allowing cross-repo overwrites.β¦
π₯ **Affected**: **Gogs (Go Git Service)**. π¦ **Versions**: All versions **prior to 0.14.2**. π’ **Vendor**: Gogs Team. Self-hosted Git service users are at risk.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Attacker Actions**: Overwrite LFS objects between repositories. π **Impact**: **High Integrity (I:H)** impact. Can inject malicious binaries or scripts into trusted projects.β¦
β‘ **Threshold**: **Low**. CVSS: **AV:N/AC:L/PR:N/UI:N**. No authentication required. No user interaction needed. Network accessible. πͺ **Entry**: Easy remote exploitation.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π§ͺ **Public Exp?**: **No PoCs listed** in data. However, GHSA advisory exists. π **Wild Exp**: Not confirmed public, but severity suggests high risk. Check GHSA-cj4v-437j-jq4c for details.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Gogs instances. π **Version Check**: Verify if running < 0.14.2. π **LFS Check**: Inspect Large File Storage configurations for cross-repo isolation failures. Use CVSS vector analysis.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: **Yes**. π οΈ **Patch**: Upgrade to **Gogs v0.14.2**. π **Ref**: See GitHub release notes and commit 81ee883. Official mitigation is available.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Isolate LFS storage. π« **Restrict Access**: Limit network exposure if possible. π **Monitor**: Watch for anomalous file changes in LFS directories. β οΈ **Risk**: High exposure until patched.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π **Published**: 2026-03-05. π **CVSS**: 7.5 (High). π **Action**: Patch immediately. Supply chain risks are critical. Do not delay.
