The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the key space within a feasible time window.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-331"],"references":["https://github.com/fr3akhacks/cve-disclosures/blob/master/osTicket/CVE-2026-38447.md","https://github.com/osTicket/osTicket/blob/v1.18.3/include/class.api.php#L149","https://github.com/osTicket/osTicket/blob/v1.18.3/include/class.misc.php","https://github.com/osTicket/osTicket/commit/feccb6a3a90863fd31215ee738b39762177e658c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-38447","score":0.00671,"percentile":0.52051,"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).
