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."},{"lang":"es","value":"AgenticMail proporciona a los agentes de IA direcciones de correo electrónico y números de teléfono reales. En @agenticmail/api, anterior a la versión 0.9.64, un agente de AgenticMail autenticado con bajos privilegios puede enumerar las tareas pendientes/reclamadas de otro agente al proporcionar el nombre del agente objetivo a GET /api/agenticmail/tasks/pending?assignee=[name]. Los objetos de tarea devueltos incluyen los ID de tarea y las cargas útiles. Los mismos ID de tarea pueden luego ser utilizados con los puntos finales de mutación de tareas de estilo de capacidad (/tasks/:id/claim, /tasks/:id/result, /tasks/:id/complete, /tasks/:id/fail) para reclamar, completar o fallar tareas asignadas a un agente diferente. Debido a que los agentes autenticados ordinarios pueden descubrir nombres de agentes a través de GET /api/agenticmail/accounts/directory, el ID de tarea deja de ser efectivamente una capacidad secreta. Esto convierte el modelo de capacidad previsto en una omisión de autorización entre agentes. La versión 0.9.64 contiene una corrección."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"agenticmail","product":"@agenticmail/api","versions":[{"version":"< 0.9.64","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-07-21T13:13:34.696485Z","id":"CVE-2026-57494","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-639"},{"lang":"en","value":"CWE-862"}]}],"references":[{"url":"https://github.com/agenticmail/agenticmail/security/advisories/GHSA-hjwc-26pj-v3pm","source":"security-advisories@github.com"},{"url":"https://github.com/agenticmail/agenticmail/security/advisories/GHSA-hjwc-26pj-v3pm","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
