CVE-2026-45713 Mailpit: Unauthenticated remote memory-exhaustion DoS via unlimited SMTP DATA and /api/v1/send body sizes

Mailpit is an email testing tool and API for developers. Prior to version 1.30.0, the Mailpit SMTP server has a Server.MaxSize int field that controls the maximum allowed DATA payload size, but the field is never assigned anywhere outside test code, leaving it at Go's zero value 0 ⇒ "no limit". T...

CVE-2026-63091

ProFTPD before 1.3.9c and 1.3.10rc3 contains a signed integer overflow vulnerability in the modsftp module's SCP size-record parser that allows authenticated low-privilege attackers to bypass ASLR by sending a crafted file size value of UINT64MAX, which results in a negative offt value. Attackers...
