Unauthenticated attackers on default installs can save filtertags markup in a page with a trailing-backslash token that breaks quote parity under MySQL backslash escaping. This lets them inject a five-column UNION subquery to read arbitrary table data such as password hashes.","state":0,"publishedAt":"2026-10-02T11:38:27.011+00:00","modifiedAt":"2026-10-06T16:16:45.803+00:00","affected":[{"ecosystem":"Vendor product","name":"yeswiki","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"YesWiki\",\n                    \"product\": \"yeswiki\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"4.6.7\"\n                        },\n                        {\n                            \"version\": \"4.6.7\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N","score":8.8,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","score":8.6,"severity":"HIGH"}],"references":["https://github.com/YesWiki/yeswiki/security/advisories/GHSA-p87r-f4x4-8r4g","https://www.vulncheck.com/advisories/yeswiki-before-4.6.7-sql-injection-via-filtertags-filtern-parameter"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104457","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104457","identifiers":["CVE-2026-104457"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
