What it is

YesWiki before 4.6.7 contains a second-order SQL injection vulnerability in AclService::updateRequestWithACL, where a stored username is concatenated unescaped into a read-ACL LIKE clause. Attackers can self-register an account name containing a double-quote payload, then load non-admin ACL-filtered listings to read database contents and bypass read ACLs.
