Summary

YesWiki from 4.6.0 before 4.7.0 and from 5.0.0-alpha1 before 5.0.0-alpha4 contains an SQL injection flaw in the Bazar entries search API. Field names taken from the query and searchfields parameters are placed in a backtick-quoted alias that is escaped only with mysqli_real_escape_string, a flaw classified as CWE-89. An unauthenticated remote attacker can inject subqueries to read data such as user password hashes or exhaust database threads with SLEEP().
