medium Tenable Self-Hosted Container Security Plugin ID 442415

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to
 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Mime\Header\ParameterizedHeader validates and
 encodes parameter values but emits parameter names verbatim, allowing a caller that derives a parameter
 name from untrusted input to include CRLF or other non-token bytes and inject additional headers into
 rendered structured mail headers such as Content-Type or Content-Disposition. This issue is reported as
 fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12. (CVE-2026-45070)

Solution

Update the symfony/mime library and its related packages to version 5.4.52 or later.
