Attackers can exploit the temporary-download endpoint's insufficient Content-Security-Policy sandbox to execute scripts when the attachment is opened, enabling theft of the victim's credentials and mailbox contents. Proofpoint Threat Research has observed exploitation in the wild as a credential and mailbox stealer.","state":0,"publishedAt":"2026-10-27T16:10:08.568+00:00","modifiedAt":"2026-10-28T16:16:12.399+00:00","affected":[{"ecosystem":"Vendor product","name":"GFI KerioConnect","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"GFI USA, LLC\",\n                    \"product\": \"GFI KerioConnect\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.0.8p2\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/SI:L/SA:N","score":6.2,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2,"severity":"HIGH"}],"references":["https://gfi.ai/resource/kerioconnect-product-releases/","https://www.vulncheck.com/advisories/gfi-kerioconnect-8p2-stored-xss-via-svg-attachment"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112353","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112353","identifiers":["CVE-2026-112353"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
