{"cve":"CVE-2026-56840","nvd":{"published":"2026-10-23T12:18:15.510","modified":"2026-10-23T12:18:15.627","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-79"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-63v4-w882-g4x2"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-56840","score":0.00246,"percentile":0.15723,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-63v4-w882-g4x2","url":"https://osv.dev/vulnerability/GHSA-63v4-w882-g4x2","summary":"PraisonAI: HTTPApproval dashboard renders tool arguments as raw HTML, allowing approval-page XSS to approve dangerous tools","modified":"2026-07-23T15:11:47.942750129Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.5.2 <4.6.59"],"fixed":["4.6.59"]}]},{"id":"PYSEC-2026-3503","url":"https://osv.dev/vulnerability/PYSEC-2026-3503","summary":"PraisonAI: HTTPApproval dashboard renders tool arguments as raw HTML, allowing approval-page XSS to approve dangerous tools","modified":"2026-07-23T15:00:16.555962349Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.5.2 <4.6.59"],"fixed":["4.6.59"]}]}],"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).
