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.","state":0,"publishedAt":"2026-10-23T11:58:24.568+00:00","modifiedAt":"2026-10-23T11:58:24.568+00:00","affected":[{"ecosystem":"Vendor product","name":"PraisonAI","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MervinPraison\",\n                    \"product\": \"PraisonAI\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.5.2, < 4.6.59\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-63v4-w882-g4x2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56840","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56840","identifiers":["CVE-2026-56840"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
