Attackers can host a repository whose default branch is named --pathspec-from-file=<path>, causing cloning applications that check out the active branch to leak file contents through GitCommandError messages.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-88"],"vendors":[],"products":[],"references":[{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-23mf-xhv8-69c2","tags":[]},{"url":"https://www.vulncheck.com/advisories/gitpython-before-3.2.0-arbitrary-file-read-via-head-checkout-branch-name","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-23mf-xhv8-69c2","tags":[]}],"exploitRefs":[{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-23mf-xhv8-69c2","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-23mf-xhv8-69c2","tags":[]}],"hasPoc":true,"ai":null}
