Description
YesWiki from 4.2.0 before 4.7.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject script into comment bodies using the wakka raw-HTML syntax. Attackers can post comments via the /api/comments endpoint that render unescaped through the Twig raw filter, executing JavaScript in administrators' and visitors' sessions.
