A session key prefixed with “!” 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 “Fix object injection primitive in rcube_session::unserialize() via “!”-prefixed session keys”, which rejects such keys.","state":0,"publishedAt":"2026-10-22T01:48:23.338+00:00","modifiedAt":"2026-10-22T01:48:23.338+00:00","affected":[{"ecosystem":"Vendor product","name":"Webmail","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Webmail\",\n                    \"repo\": \"https://github.com/roundcube/roundcubemail/\",\n                    \"vendor\": \"Roundcube\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"1.6.20\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.6.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"1.7.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.7.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":7.4,"severity":"HIGH"}],"references":["https://bugs.debian.org/1151279","https://github.com/roundcube/roundcubemail/commit/93284f3f0e13f99af37fc3b81861e142eea8a922","https://roundcube.net/news/2026/10/19/security-updates-1.6.20-and-1.7.5","https://github.com/roundcube/roundcubemail/releases/tag/1.7.5","https://github.com/roundcube/roundcubemail/releases/tag/1.6.20","https://github.com/roundcube/roundcubemail/commit/833770d3d3c35cfde74cc2614d368f25a75b6f99"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114724","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114724","identifiers":["CVE-2026-114724"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
