In version 0.19.2, IsPasswordMatch in backend/db/models.go falls back to a hard-coded bcrypt(\"null\") placeholder whenever a user has no stored password. OIDC-registered users are created with an empty password, so anyone who submits password: \"null\" to the internal login endpoint receives a valid session for that user. The bypass is unauthenticated and requires no user interaction. This issue has been patched in version 0.19.3.","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:L","score":9.4},"cwes":["CWE-287"],"references":["https://github.com/enchant97/note-mark/releases/tag/v0.19.3","https://github.com/enchant97/note-mark/security/advisories/GHSA-pxf8-6wqm-r6hh","https://github.com/enchant97/note-mark/security/advisories/GHSA-pxf8-6wqm-r6hh"],"products":[],"source":"nvd","synced_at":"2026-10-26T19:31:02.781428341+00:00"},"epss":{"cve":"CVE-2026-41571","score":0.00296,"percentile":0.22086,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-pxf8-6wqm-r6hh","url":"https://osv.dev/vulnerability/GHSA-pxf8-6wqm-r6hh","summary":"Note Mark: OIDC-registered users authenticated by submitting password \"null\"","modified":"2026-06-25T23:11:43.173659837Z","packages":[{"ecosystem":"Go","name":"github.com/enchant97/note-mark/backend","purl":"pkg:golang/github.com/enchant97/note-mark/backend","ranges":["<0.0.0-20260417132909-dea5530cc989"],"fixed":["0.0.0-20260417132909-dea5530cc989"]}]},{"id":"GO-2026-5557","url":"https://osv.dev/vulnerability/GO-2026-5557","summary":"Note Mark: OIDC-registered users authenticated by submitting password \"null\" in github.com/enchant97/note-mark/backend","modified":"2026-06-25T23:01:31.736709250Z","packages":[{"ecosystem":"Go","name":"github.com/enchant97/note-mark/backend","purl":"pkg:golang/github.com/enchant97/note-mark/backend","ranges":["<0.0.0-20260417132909-dea5530cc989"],"fixed":["0.0.0-20260417132909-dea5530cc989"]}]}],"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).
