Upstream fixed this in the commit “Fix remote content blocking bypass via CSS escapes in FuncIRI attributes (again)”, which resolves CSS escapes before matching and also inspects the `to`, `from` and `by` attributes.","state":0,"publishedAt":"2026-10-22T02:02:49.325+00:00","modifiedAt":"2026-10-26T16:46:46.332+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:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://bugs.debian.org/1151279","https://github.com/roundcube/roundcubemail/commit/2f74267f0e13bed7182b1d2294cc4f3c5c46dcee","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/ff4fcfdd2952f9d09947cc9c18137f381f27caf1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114728","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114728","identifiers":["CVE-2026-114728"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
