The application exposes passkey registration endpoints without requiring prior authentication. Any successfully authenticated passkey is automatically granted an administrator token, allowing full administrative access to the application. This enables a complete compromise of the application without requiring any existing credentials. Version 1.8.71 fixes the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","score":8.9},"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-284"],"references":["https://github.com/franklioxygen/MyTube/commit/d6c1275a7ff7ffd3d51b53c333237f4d572580ac","https://github.com/franklioxygen/MyTube/security/advisories/GHSA-378w-xh68-qrc8","https://github.com/franklioxygen/MyTube/security/advisories/GHSA-378w-xh68-qrc8"],"products":["franklioxygen:mytube"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33890","score":0.00501,"percentile":0.42913,"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).
