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."}], "lastModified": "2026-10-29T14:31:52.580", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:roundcube:webmail:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D91A1C10-A81F-420B-9DE2-078A9BBA469D", "versionEndExcluding": "1.6.20", "versionStartIncluding": "1.6.0"}, {"criteria": "cpe:2.3:a:roundcube:webmail:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D41F4166-D4C5-4D1C-94AC-3CF3C27F1319", "versionEndExcluding": "1.7.5", "versionStartIncluding": "1.7.0"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
