The scan enumerated the drive with rglob(), which in CPython does not descend into symlinked directories and treats the symlink as an ordinary directory, while O_NOFOLLOW on the hash side binds only the final path component. An evil-maid attacker with physical access to the removable drive could replace a tool-tree directory with a symlink to a copy containing byte-identical files plus a planted __pycache__/*.pyc file (which CPython loads in preference to recompiling the clean .py). The planted file is never enumerated, added_files stays 0, and verify-usb reports PASSED, resulting in code execution when the victim runs the portable install. Fixed in 1.4.9 (affects both 1.4.x and 1.5.x lines).","state":0,"publishedAt":"2026-08-27T14:50:55.418+00:00","modifiedAt":"2026-10-01T15:21:23.408+00:00","affected":[{"ecosystem":"Vendor product","name":"openssl_encrypt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jahlives\",\n                    \"product\": \"openssl_encrypt\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/openssl-encrypt\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.4.9\"\n                        },\n                        {\n                            \"version\": \"1.4.9\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H","score":7.3,"severity":"HIGH"}],"references":["https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-hw7h-wqf5-6crx","https://www.vulncheck.com/advisories/verify-usb-before-1.4.9-symlink-directory-traversal-code-execution"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-81690","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-81690","identifiers":["CVE-2026-81690"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
