GHSA-v3q9-hj7j-63hq: aiosmtplib vulnerable to SMTP command injection via CR/LF in sender/recipient addressCVE-2026-53533 0 The aiosmtplib library versions prior to 5.1.1 are vulnerable to SMTP command injection via CR/LF characters embedded in sender or recipient email addresses. This allows an attacker to inject arbitrary SMTP commands into the session by including carriage return and line feed sequences in the address strings passed to SMTP methods such as mail(), rcpt(), vrfy(), and expn(). The vulnerability can cause the client to hang or allow sending of arbitrary messages if the attacker controls the envelope sender or recipient data. The issue affects aiosmtplib 5.1.0 and all earlier versions. Join the discussion | GCVE Database | 07/07/2026, 23:40:52 UTC Added: 07/08/2026, 13:21:43 UTC |
