YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar nuagetag action, which concatenates the unescaped tags attribute into a raw SQL IN clause. Attackers with page-write access (unauthenticated on default installs) can embed a nuagetag tag ending in a backslash to break quote parity and inject a UNION subquery, exfiltrating password hashes and arbitrary table data.
