In @agenticmail/api prior to version 0.9.64, a low-privileged authenticated AgenticMail agent can enumerate another agent's pending/claimed tasks by supplying the target agent name to `GET /api/agenticmail/tasks/pending?assignee=<name>`. The returned task objects include the task IDs and payloads. The same task IDs can then be used with the capability-style task mutation endpoints (`/tasks/:id/claim`, `/tasks/:id/result`, `/tasks/:id/complete`, `/tasks/:id/fail`) to claim, complete, or fail tasks assigned to a different agent. Because ordinary authenticated agents can discover agent names through `GET /api/agenticmail/accounts/directory`, the task ID effectively stops being a secret capability. This turns the intended capability model into a cross-agent authorization bypass. Version 0.9.64 contains a fix.","state":0,"publishedAt":"2026-07-20T22:01:43.891+00:00","modifiedAt":"2026-07-21T14:56:03.184+00:00","affected":[{"ecosystem":"Vendor product","name":"@agenticmail/api","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"agenticmail\",\n                    \"product\": \"@agenticmail/api\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.9.64\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/agenticmail/agenticmail/security/advisories/GHSA-hjwc-26pj-v3pm"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57494","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57494","identifiers":["CVE-2026-57494"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
