{"id":"CVE-2026-33954","state":"PUBLISHED","title":"LinkAce discloses private notesto unauthorized authenticated users via the web link detail page","description":"LinkAce is a self-hosted archive to collect website links. In versions prior to 2.5.3, a private note attached to a non-private link can be disclosed to a different authenticated user via the web interface. The API appears to correctly enforce note visibility, but the web link detail page renders notes without applying equivalent visibility filtering. As a result, an authenticated user who is allowed to view another user's `internal` or `public` link can read that user's `private` notes attached to the link. Version 2.5.3 patches the issue.","publishedAt":"2026-03-27T21:23:30.148Z","updatedAt":"2026-03-27T21:57:41.206Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Kovah LinkAce"],"affected":[{"vendor":"Kovah","product":"LinkAce","versions":[{"version":"< 2.5.3","status":"affected"}]}],"references":["https://github.com/Kovah/LinkAce/security/advisories/GHSA-88h3-cq25-vw8q"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33954.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33954","state":"PUBLISHED","datePublished":"2026-03-27T21:23:30.148Z","dateUpdated":"2026-03-27T21:57:41.206Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-24T19:50:52.106Z"},"containers":{"cna":{"title":"LinkAce discloses private notesto unauthorized authenticated users via the web link detail page","descriptions":[{"lang":"en","value":"LinkAce is a self-hosted archive to collect website links.
