{"id":"CVE-2026-41192","state":"PUBLISHED","title":"FreeScout's client-controlled attachment IDs allow deletion of existing conversation attachments","description":"FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, the reply and draft flows trust client-supplied encrypted attachment IDs. Any IDs present in `attachments_all[]` but omitted from retained lists are decrypted and passed directly to `Attachment::deleteByIds()`. Because `load_attachments` returns encrypted IDs for attachments on a visible conversation, a mailbox peer can replay those IDs through `save_draft` and delete the original attachment row and file. Version 1.8.215 fixes the vulnerability.","publishedAt":"2026-04-21T17:12:42.628Z","updatedAt":"2026-04-21T19:01:14.512Z","severity":{"score":7.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["freescout-help-desk freescout"],"affected":[{"vendor":"freescout-help-desk","product":"freescout","versions":[{"version":"< 1.8.215","status":"affected"}]}],"references":["https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-cv36-2j23-x6g3","https://github.com/freescout-help-desk/freescout/commit/5f182818e2391f8e711fec6ae6648ac0b367bef5","https://github.com/freescout-help-desk/freescout/releases/tag/1.8.215"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41192.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41192","state":"PUBLISHED","datePublished":"2026-04-21T17:12:42.628Z","dateUpdated":"2026-04-21T19:01:14.512Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-18T02:51:52.973Z"},"containers":{"cna":{"title":"FreeScout's client-controlled attachment IDs allow deletion of existing conversation attachments","descriptions":[{"lang":"en","value":"FreeScout is a free self-hosted help desk and shared mailbox.
