1) Improper Certificate Validation (CVE-ID: CVE-2026-8286)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass TLS certificate validation.

The vulnerability exists due to improper certificate validation in connection reuse logic for STARTTLS-enabled protocol handling when reusing an existing live connection for a new transfer. A remote attacker can cause a transfer to reuse a connection with mismatched TLS settings to bypass TLS certificate validation.

This affects transfers using IMAP, POP3, SMTP, FTP, or LDAP schemes that begin in cleartext and are upgraded to TLS with STARTTLS.
