Data compromise via storage and relay validation gaps
Published Jul 20, 2026 · Updated Jul 20, 2026
Improper input validation in AgenticMail @agenticmail/api before 0.9.32 and @agenticmail/core before 0.9.10 allows remote attackers to alter data. Storage routes embed unchecked identifiers and HAVING text into SQL and miss comma-joined table ownership, while core ships an outbound-worker fallback secret, accepts SMTP control characters, and disables certificate verification by default. Remote authenticated users can reach storage routes; the shipped secret and unsafe relay defaults expose outbound messages and credentials to remote or man-in-the-middle attackers.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
