AI risk analysis

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.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to YesWiki 4.6.7 or later.

NVD 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.
