{"id":"CVE-2026-47406","aliases":["GHSA-4x6r-9v57-3gqw","PYSEC-2026-2928"],"url":"https://o3.security/vulnerability/CVE-2026-47406","summary":"praisonai-platform: Dependency endpoints accept any issue_id and dep_id without workspace ownership check, cross-workspace issue linking + read + delete IDOR","details":"PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an Insecure Direct Object Reference. The dependency endpoints (`POST/GET /workspaces/{workspace_id}/issues/{issue_id}/dependencies` and `DELETE .../dependencies/{dep_id}`) gate access on `require_workspace_member(workspace_id)` only, then dispatch to `DependencyService` calls that take URL/body-supplied issue and dependency IDs without verifying any of them belong to the membership-checked workspace. Most damaging: `create_dependency` accepts `body.depends_on_issue_id` from the request body — that ID is checked against nothing — letting an attacker create a \"blocks\" or \"related\" link between any two issues anywhere in the database. PraisonAI Platform version 0.1.4 patches the issue.","published":"2026-07-21T16:37:12.672Z","modified":"2026-08-12T03:51:11.445161321Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.00231,"percentile":0.14221,"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/ef79b7a0561796ad9807f0f09538c25cc78d3619","label":"MervinPraison/PraisonAI@ef79b7a"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47406.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-4x6r-9v57-3gqw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47406"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/ef79b7a0561796ad9807f0f09538c25cc78d3619"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/pull/1685"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.445161321Z"}}
