ImapEngine affected by command injection via the ID command parameters
Quick fix
GHSA-rfq9-4wcm-64gh — directorytree/imapengine: upgrade to the fixed version with the command below.
composer require directorytree/imapengine:^1.22.3Details
Versions of the package `directorytree/imapengine` before 1.22.3 are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the id() function in ImapConnection.php due to improperly escaping user input before including it in IMAP ID commands. This allows attackers to read or delete victim's emails, terminate the victim's session or execute any valid IMAP command on victim's mailbox by including quote characters `"` or CRLF sequences `\r\n` in the input.
