{"id":"CVE-2026-104457","published":"2026-10-02T12:17:17.653","lastModified":"2026-10-06T17:17:12.897","description":"YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar filtertags action, which wraps unescaped filterN attribute tokens in quotes and concatenates them into a raw tags.value IN (...) clause. 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.","cvssScore":8.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","cwes":["CWE-89"],"vendors":[],"products":[],"references":[{"url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-p87r-f4x4-8r4g","tags":[]},{"url":"https://www.vulncheck.com/advisories/yeswiki-before-4.6.7-sql-injection-via-filtertags-filtern-parameter","tags":[]},{"url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-p87r-f4x4-8r4g","tags":[]}],"exploitRefs":[{"url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-p87r-f4x4-8r4g","tags":[]},{"url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-p87r-f4x4-8r4g","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows unauthenticated attackers to inject SQL queries, potentially reading sensitive data such as password hashes.","exploitability":"Exploitation is relatively straightforward for unauthenticated attackers, requiring only a default install with the filtertags feature enabled.","blast_radius":"If exploited, attackers could read arbitrary table data, posing a significant risk to user authentication and data integrity.","remediation":"Upgrade to YesWiki 4.6.7 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["sql-injection","rce","web","unauth","data-leak"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-04T08:41:24.585Z"}}
