Description
YesWiki before 4.7.0 contains a stored cross-site scripting vulnerability in the filtertags action, which echoes attacker-controlled token values without output encoding. Anonymous attackers can inject markup via action-attribute parameters that bypasses the allow_raw_html gate, executing JavaScript for every page viewer.
