{"cve":"CVE-2026-57494","nvd":{"published":"2026-07-20T22:17:16.970","modified":"2026-10-24T20:10:00.137","status":"Deferred","description":"AgenticMail gives AI agents real email addresses and phone numbers. 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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-639","CWE-862"],"references":["https://github.com/agenticmail/agenticmail/security/advisories/GHSA-hjwc-26pj-v3pm","https://github.com/agenticmail/agenticmail/security/advisories/GHSA-hjwc-26pj-v3pm"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-57494","score":0.00273,"percentile":0.19507,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-hjwc-26pj-v3pm","url":"https://osv.dev/vulnerability/GHSA-hjwc-26pj-v3pm","summary":"AgenticMail: Cross-agent task authorization bypass in AgenticMail API","modified":"2026-07-20T22:26:45.921845Z","packages":[{"ecosystem":"npm","name":"@agenticmail/api","purl":"pkg:npm/%40agenticmail/api","ranges":["<0.9.64"],"fixed":["0.9.64"]}]}],"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).
