{"id":"CVE-2026-44785","summary":"Discourse: Hidden reply-to post raw can be disclosed through AI explain prompts","details":"Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.4, 2026.3.0-latest to before 2026.3.1, and 2026.4.0-latest to before 2026.4.1, the AI \"explain\" helper only checks can_see? on the post being explained, not its reply_to_post, so any authenticated user with access to the AI helper could read the raw contents of a hidden parent post by invoking \"Explain\" on a reply to it. This issue has been patched in versions 2026.1.4, 2026.3.1, 2026.4.1, and 2026.5.0-latest.1.","aliases":["BIT-discourse-2026-44785","GHSA-7h76-fwxc-j586"],"modified":"2026-07-08T08:26:13.928571107Z","published":"2026-06-12T20:24:39.155Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44785.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44785.json"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-7h76-fwxc-j586"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44785"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/discourse/discourse","events":[{"introduced":"322d3c0ac6a8f133b3f82875e9dbbe310f638c1b"},{"fixed":"ec5d54b3291729ec201615c64d954545000896b9"},{"introduced":"896e810e1b296478bba91559a8fc89a9926f11fe"},{"fixed":"211de17ca39dec7bcb6afebdc9c79cebdc0b4495"},{"introduced":"fdd750d960e603415db62242eca3c30d68e366db"},{"fixed":"6bb9b59d5d3f5d0c813187a102318e9e4ae49647"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2026.1.0-latest"},{"fixed":"2026.1.4"},{"introduced":"2026.3.0-latest"},{"fixed":"2026.3.1"},{"introduced":"2026.4.0-latest"},{"fixed":"2026.4.1"}]}}],"versions":["2026.5.0","v2026.4.0","v2026.1.3","v2026.3.0","v2026.4.0-latest","v2026.1.2","v2026.3.0-latest.1","v2026.1.1","v2026.3.0-latest","v2026.1.0","stable","esr","v2026.1.0-latest"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44785.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
