During forced checkout with overwrite_existing enabled, attackers can craft malicious repository trees where symlink entries replace validated directories, causing subsequent files to be written outside the worktree through the symlink for code execution or file manipulation.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-59"],"references":["https://github.com/GitoxideLabs/gitoxide","https://github.com/GitoxideLabs/gitoxide/blob/gix-fs-v0.22.1/gix-fs/src/stack.rs#L185-L196","https://github.com/GitoxideLabs/gitoxide/commit/b62498378b8bc2c95863a044b700f2063b0b5875","https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-6p9q-f2xg-6pr5","https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-f89h-2fjh-2r9q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-100419","score":0.00222,"percentile":0.12873,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
