{"id":"CVE-2026-56840","published":"2026-10-23T12:18:15.510","lastModified":"2026-10-23T12:18:15.627","description":"PraisonAI is a multi-agent teams system. From version 4.5.2 to before version 4.6.59, praisonai.bots.HTTPApproval renders pending tool approval arguments directly into the approval dashboard HTML. An attacker-controlled tool argument can inject JavaScript into that page. When a human opens the approval URL to inspect the risky tool request, the script runs in the dashboard origin and can POST to the same request's /approve/{request_id}/decide endpoint, causing HTTPApproval to return approved=True. This issue has been patched in version 4.6.59.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-63v4-w882-g4x2","tags":[]}],"exploitRefs":[{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-63v4-w882-g4x2","tags":[]}],"hasPoc":true,"ai":null}
