In versions 1.19.1 and below, an attacker can craft a malicious Git packfile to exploit the PACK signature detection in the parsePush.ts file. By embedding a misleading PACK signature within commit content and carefully constructing the packet structure, the attacker can trick the parser into treating invalid or unintended data as the packfile. Potentially, this would allow bypassing approval or hiding commits. This issue is fixed in version 1.19.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N","score":7.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N","score":5.7},"cwes":["CWE-115"],"references":["https://github.com/finos/git-proxy/commit/333c98a165a5a1ec88414db3d4a2c6f81e083e0f","https://github.com/finos/git-proxy/commit/a620a2f33c39c78e01783a274580bf822af3cc3a","https://github.com/finos/git-proxy/releases/tag/v1.19.2","https://github.com/finos/git-proxy/security/advisories/GHSA-xxmh-rf63-qwjv"],"products":["finos:gitproxy"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-54584","score":0.00571,"percentile":0.47266,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xxmh-rf63-qwjv","url":"https://osv.dev/vulnerability/GHSA-xxmh-rf63-qwjv","summary":"GitProxy Backfile Parsing Exploit","modified":"2025-07-31T11:18:40Z","packages":[{"ecosystem":"npm","name":"@finos/git-proxy","purl":"pkg:npm/%40finos/git-proxy","ranges":["<1.19.2"],"fixed":["1.19.2"]}]}],"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).
