{"schema":"threatline.record/2","record":{"id":"CVE-2026-112353","aliases":[],"summary":"GFI KerioConnect < 10.0.8p2 Stored XSS via SVG Attachment","details":"GFI KerioConnect (Kerio Connect) before 10.0.8 Patch 2 contains a stored cross-site scripting vulnerability in the Webmail component that allows a remote attacker to run JavaScript in a victim's authenticated Webmail session by uploading a crafted SVG email attachment that bypasses sanitization of event-handler attributes. 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.","categories":["Unclassified"],"product":"GFI KerioConnect","vendor":"GFI USA, LLC","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112353","source_modified_at":"2026-10-27T16:10:08.568Z","fetched_at":"2026-10-27T16:27:21.584480Z","product":"GFI KerioConnect","vendor":"GFI USA, LLC","versions":[{"status":"affected","version":"0","versionType":"custom","lessThan":"10.0.8p2"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112353","source_modified_at":"2026-10-27T16:10:08.568Z","fetched_at":"2026-10-27T16:27:21.584480Z","package":{"name":"GFI KerioConnect","ecosystem":null},"version":"10.0.8p2","basis":"first unaffected version stated in the CVE record"}],"cvss":6.2,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T16:10:08.568Z","modified_at":"2026-10-27T16:10:08.568Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112353","fetched_at":"2026-10-27T16:27:21.584480Z","source_modified_at":"2026-10-27T16:10:08.568Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://gfi.ai/resource/kerioconnect-product-releases/","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/gfi-kerioconnect-8p2-stored-xss-via-svg-attachment","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T16:10:08.568Z","content_hash":"44cd647b7fa0d841cd100812dc8a15a40226f19d433ad9c8a869d5bc5e909e94"}}
