Prior to 2.7.8, privileged package fetch and cache-cleaning operations used race-prone path handling across libmport/fetch.c, libmport/clean.c, libmport/util.c, libmport/bundle_read_install_pkg.c, libmport/delete_primative.c, and libexec/mport.create/mport.create.c. A local attacker with write access to a participating package cache or staging path could race path checks and replacement operations to redirect package downloads, cleanup, or install-related side effects outside the intended cache. The affected lifecycle helper paths also used shell-form invocation, increasing command-line interpretation risk during privileged helper execution. This issue is fixed in version 2.7.8.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","score":5.8},"cvss_v3":null,"cwes":["CWE-78","CWE-367"],"references":["https://github.com/MidnightBSD/mport/commit/29154b0fdfb5806568ed1277e88d942bad6d1169","https://github.com/MidnightBSD/mport/pull/118","https://github.com/MidnightBSD/mport/releases/tag/2.7.8","https://github.com/MidnightBSD/mport/security/advisories/GHSA-h387-g4pf-28cj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-54575","score":0.00122,"percentile":0.01929,"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).
