{"apiVersion":"1.0","identifier":"CVE-2026-81690","description":"openssl-encrypt (pip package) before 1.4.9 contains a symlink-following flaw in its verify-usb v2 added-file allowlist scan. 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).","publishedAt":"2026-08-27T17:20:58","lastModifiedAt":"2026-08-27T20:18:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81690","cvssScore":7.3,"cvssVector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H","epssProbability":0.00487,"riskScore":0.76,"affectedProduct":"openssl-encrypt","affectedVersions":"<1.4.9","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81690","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81690","en":"https://www.redsauce.net/en/cves/CVE-2026-81690","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81690","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81690","de":"https://www.redsauce.net/de/cves/CVE-2026-81690","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81690","el":"https://www.redsauce.net/el/cves/CVE-2026-81690"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81690"}}
