CVE-2026-47255
What it is
AgenticMail gives AI agents real email addresses and phone numbers. @agenticmail/api prior to version 0.9.32 and @agenticmail/core prior to version 0.9.10 had weakness related to validation and and binding of inactive-agent hour filtering; storage SQL identifier validation; metadata-backed ownership checks for raw storage SQL; blocking direct storage metadata access through raw SQL; fail-closed outbound worker secret handling; SMTP envelope/header control-character validation before command construction; and TLS certificate verification as the default for MailSender with an explicit opt-out for local development. @agenticmail/api prior to version 0.9.32 and @agenticmail/core prior to version 0.9.10 are patched.
