SCA: security update for zbateson/mail-mime-parser (GHSA-36h5-qg4p-q2qf)

high Tenable Cloud Security Plugin ID 448350

Description

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

 - zbateson/mail-mime-parser is a mail mime parser alternative to PHP's imap* functions and Pear libraries
 for reading messages in Internet Message Format RFC 822. Prior to version 3.0.6 and 4.0.2, CRLF (carriage-
 return / line-feed) header injection (CWE-93) affecting any application that uses this library to build or
 forward MIME messages with an attacker-influenced attachment filename. Attachment filenames are
 interpolated into the `Content-Type` and `Content-Disposition` header values without stripping CR/LF, so a
 filename containing `\r\n` serializes as one or more additional, attacker-controlled header lines (for
 example a forged `Bcc:` that silently exfiltrates a copy of the outgoing message). The untrusted filename
 can come directly from parsed inbound mail, so no local construction is required — an application that re-
 attaches or re-sends a parsed filename is exposed. Versions 3.0.6 and 4.0.2 patch the issue. Versions 1.x
 and 2.x are also affected but are end-of-life and will not receive patches; users on those lines should
 upgrade to a fixed release. If upgrading is not immediately possible, strip CR and LF from any filename
 before passing it to attachment APIs, and from the result of getFilename() before reusing it in a
 constructed message — e.g. preg_replace('/[\r\n]+/', ' ', $filename). (CVE-2026-61815)

Solution

Update the zbateson/mail-mime-parser library and its related packages to version 3.0.6 or later.
