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.","state":0,"publishedAt":"2026-05-04T17:42:32.428+00:00","modifiedAt":"2026-05-04T20:20:53.632+00:00","affected":[{"ecosystem":"Vendor product","name":"note-mark","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"enchant97\",\n                    \"product\": \"note-mark\",\n                    \"versions\": [\n                        {\n                            \"version\": \"= 0.19.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"CRITICAL"}],"references":["https://github.com/enchant97/note-mark/security/advisories/GHSA-pxf8-6wqm-r6hh","https://github.com/enchant97/note-mark/releases/tag/v0.19.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41571","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41571","identifiers":["CVE-2026-41571"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
