Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A Path Traversal flaw in `go-git`. ๐ **Consequences**: Attackers can create/modify files across file systems. ๐ฅ **Impact**: High risk to Confidentiality, Integrity, and Availability (CVSS 9.8).
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **CWE**: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). ๐ **Flaw**: Insufficient validation allows traversing outside intended directories.
Q3Who is affected? (Versions/Components)
๐ฆ **Vendor**: go-git. ๐งฉ **Product**: go-git library. โ ๏ธ **Affected**: Versions **prior to v5.11**. โ **Safe**: v5.11 and later.
Q4What can hackers do? (Privileges/Data)
๐ป **Privileges**: No authentication required (PR:N). ๐ **Data**: Full read/write access to arbitrary files. ๐ **Scope**: Cross-file system manipulation allowed.
๐ **Public Exp**: No specific PoC listed in data. ๐ **Reference**: GitHub Security Advisory (GHSA-449p-3h89-pw88) available. โ ๏ธ **Risk**: High CVSS suggests easy exploitation logic.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for `go-git` usage in Go projects. ๐ **Version**: Verify if version < 5.11. ๐ ๏ธ **Tool**: Use dependency scanners to detect vulnerable library versions.
Q8Is it fixed officially? (Patch/Mitigation)
๐ง **Fix**: Upgrade to **go-git v5.11** or higher. ๐ฅ **Source**: Official GitHub repository. ๐ **Advisory**: See GHSA-449p-3h89-pw88 for details.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If upgrade impossible, restrict file system access permissions. ๐ **Mitigation**: Implement strict input validation on git operations manually.โฆ
