Description

YesWiki before 4.7.0 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject JavaScript by supplying query parameters matching missing Bazar field names. Attackers can craft links where BazarField::getValue() falls back to unsanitized $_REQUEST values rendered via Twig |raw templates, performing same-origin authenticated actions in victims' sessions.
