Attackers can craft a repository where a worktree symlink points to .git/hooks/post-checkout, so restoring the file from a tag writes a malicious hook for code execution.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-59"],"vendors":[],"products":[],"references":[{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-8w8g-wq8h-fq33","tags":[]},{"url":"https://www.vulncheck.com/advisories/dulwich-0.24.0-before-1.2.8-symlink-write-through-via-porcelain-checkout-paths","tags":[]}],"exploitRefs":[{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-8w8g-wq8h-fq33","tags":[]}],"hasPoc":true,"ai":null}
