{"id":"CVE-2026-50554","aliases":["GHSA-588f-fvcv-xhvf","GO-2026-5948"],"url":"https://o3.security/vulnerability/CVE-2026-50554","summary":"Note Mark: Unauthenticated disclosure of soft-deleted note metadata via deleted=true on public books in note-mark","details":"Note Mark is an open-source note-taking application. Prior to version 0.19.5, GET /api/books/{bookID}/notes is an unauthenticated endpoint that accepts a \"deleted\" query parameter. When the request is ?deleted=true, the service runs the query with Unscoped() (bypassing GORM's soft-delete scope) but keeps the read-authorization clause as \"owner_id = ? OR is_public = ?\". As a result, any unauthenticated caller can enumerate the metadata of soft-deleted (\"trashed\") notes belonging to any public book — notes the owner explicitly deleted and expected to be removed from public view. This issue has been patched in version 0.19.5.","published":"2026-09-03T15:26:42.538Z","modified":"2026-09-11T03:30:40.938810029Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":{"score":0.00243,"percentile":0.15497,"asOf":"2026-09-11"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/enchant97/note-mark/backend","fixedVersion":"0.0.0-20260601210758-9c9b72740f22"}],"fix":{"url":"https://github.com/enchant97/note-mark/commit/9c9b72740f22a06131a8f64b53bb08e3b05b81a6","label":"enchant97/note-mark@9c9b727"},"references":[{"type":"WEB","url":"https://github.com/enchant97/note-mark/releases/tag/v0.19.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50554.json"},{"type":"ADVISORY","url":"https://github.com/enchant97/note-mark/security/advisories/GHSA-588f-fvcv-xhvf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50554"},{"type":"FIX","url":"https://github.com/enchant97/note-mark/commit/9c9b72740f22a06131a8f64b53bb08e3b05b81a6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:30:40.938810029Z"}}
