{"cve":"CVE-2026-47409","nvd":{"published":"2026-07-21T17:17:09.640","modified":"2026-10-24T19:10:00.127","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-269","CWE-862"],"references":["https://github.com/MervinPraison/PraisonAI/commit/24385d64876577620f749957bd4814f162f4ca47","https://github.com/MervinPraison/PraisonAI/pull/1686","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-w388-2392-px73","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-w388-2392-px73"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-47409","score":0.00345,"percentile":0.27826,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w388-2392-px73","url":"https://osv.dev/vulnerability/GHSA-w388-2392-px73","summary":"praisonai-platform: Missing authorization on member removal enables full workspace takeover by any user regardless of role","modified":"2026-07-13T16:43:30.556244476Z","packages":[{"ecosystem":"PyPI","name":"praisonai-platform","purl":"pkg:pypi/praisonai-platform","ranges":["<0.1.4"],"fixed":["0.1.4"]}]},{"id":"PYSEC-2026-2938","url":"https://osv.dev/vulnerability/PYSEC-2026-2938","summary":"praisonai-platform: Missing authorization on member removal enables full workspace takeover by any user regardless of role","modified":"2026-07-13T16:33:01.172792656Z","packages":[{"ecosystem":"PyPI","name":"praisonai-platform","purl":"pkg:pypi/praisonai-platform","ranges":["<0.1.4"],"fixed":["0.1.4"]}]}],"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).
