CVE-2026-45755

Severity: Medium · CVSS 6.9
Published: Jul 14, 2026, 7:17:07 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.27% · Oct 22, 2026

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 7.4.12 and 8.0.12, MailtrapRequestParser::doParse() received the configured webhook secret but ignored the X-Mt-Signature HMAC header, allowing unauthenticated POST requests to inject forged Mailtrap delivery, bounce, open, click, or spam events. This issue is fixed in versions 7.4.12 and 8.0.12.
