Prior to version 1.28.3, Mailpit's SMTP server is vulnerable to Header Injection due to an insufficient Regular Expression used to validate `RCPT TO` and `MAIL FROM` addresses. An attacker can inject arbitrary SMTP headers (or corrupt existing ones) by including carriage return characters (`\\r`) in the email address. This header injection occurs because the regex intended to filter control characters fails to exclude `\\r` and `\\n` when used inside a character class. Version 1.28.3 fixes this issue.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-23829","url":"https://www.suse.com/security/cve/CVE-2026-23829"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"Advisory link for SUSE-SU-2026:0403-1","url":"https://lists.suse.com/pipermail/sle-security-updates/2026-February/024084.html"}],"title":"SUSE CVE CVE-2026-23829","tracking":{"current_release_date":"2026-02-10T00:24:54Z","generator":{"date":"2026-02-07T00:24:53Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-23829","initial_release_date":"2026-02-07T00:24:53Z","revision_history":[{"date":"2026-02-07T00:24:53Z","number":"2","summary":"references added,severity changed from  to moderate"},{"date":"2026-02-10T00:24:54Z","number":"3","summary":"references added"}],"status":"interim","version":"3"}}}
