{"id":"CVE-2026-47409","aliases":["GHSA-w388-2392-px73","PYSEC-2026-2938"],"url":"https://o3.security/vulnerability/CVE-2026-47409","summary":"praisonai-platform: Any workspace member can remove any other member (including the owner) via DELETE /workspaces/{id}/members/{user_id}","details":"PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling owner lockout. The `DELETE /workspaces/{workspace_id}/members/{user_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role=\"member\"`). Any member can remove any other member, including the workspace owner, using a single DELETE. There is no caller-role check, no target-role check, no \"cannot remove last owner\" guard. PraisonAI Platform version 0.1.4 patches the issue.","published":"2026-07-21T16:53:18.207Z","modified":"2026-08-12T03:51:28.242280429Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":{"score":0.00284,"percentile":0.21001,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"praisonai-platform","fixedVersion":"0.1.4"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47","label":"MervinPraison/PraisonAI@24385d6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47409.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-w388-2392-px73"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47409"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/pull/1686"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.242280429Z"}}
