GHSA-8j8w-wwqc-x596
Roundcube Webmail Vulnerable to Authenticated RCE via PHP Object Deserialization
Quick fix
GHSA-8j8w-wwqc-x596 — roundcube/roundcubemail: upgrade to the fixed version with the command below.
composer require roundcube/roundcubemail:^1.5.10Details
Roundcube Webmail before 1.5.10 and 1.6.x before 1.6.11 allows remote code execution by authenticated users because the _from parameter in a URL is not validated in program/actions/settings/upload.php, leading to PHP Object Deserialization.
