  "description": "Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 contains an object injection primitive in rcube_session::unserialize(). A session key prefixed with \u201C!\u201D was treated as having no value, and the reconstructed serialized string was emitted with a key but no corresponding value, desynchronizing the remainder of the input so that following session data was interpreted as a serialized value. This yields a PHP object injection primitive for an attacker able to influence stored session data. Upstream fixed this in the commit \u201CFix object injection primitive in rcube_session::unserialize() via \u201C!\u201D-prefixed session keys\u201D, which rejects such keys.",
