{"cve":"CVE-2026-50554","nvd":{"published":"2026-09-03T16:17:25.020","modified":"2026-09-09T21:09:13.080","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200","CWE-285"],"references":["https://github.com/enchant97/note-mark/commit/9c9b72740f22a06131a8f64b53bb08e3b05b81a6","https://github.com/enchant97/note-mark/releases/tag/v0.19.5","https://github.com/enchant97/note-mark/security/advisories/GHSA-588f-fvcv-xhvf","https://github.com/enchant97/note-mark/security/advisories/GHSA-588f-fvcv-xhvf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-50554","score":0.00417,"percentile":0.36013,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-588f-fvcv-xhvf","url":"https://osv.dev/vulnerability/GHSA-588f-fvcv-xhvf","summary":"Note Mark: Unauthenticated disclosure of soft-deleted note metadata via deleted=true on public books","modified":"2026-07-21T19:19:11.129840725Z","packages":[{"ecosystem":"Go","name":"github.com/enchant97/note-mark/backend","purl":"pkg:golang/github.com/enchant97/note-mark/backend","ranges":["<0.0.0-20260601210758-9c9b72740f22"],"fixed":["0.0.0-20260601210758-9c9b72740f22"]}]},{"id":"GO-2026-5948","url":"https://osv.dev/vulnerability/GO-2026-5948","summary":"Note Mark: Unauthenticated disclosure of soft-deleted note metadata via deleted=true on public books in github.com/enchant97/note-mark/backend","modified":"2026-07-21T19:15:26.348186281Z","packages":[{"ecosystem":"Go","name":"github.com/enchant97/note-mark/backend","purl":"pkg:golang/github.com/enchant97/note-mark/backend","ranges":["<0.0.0-20260601210758-9c9b72740f22"],"fixed":["0.0.0-20260601210758-9c9b72740f22"]}]}],"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).
