YesWiki before 4.6.7 Stored XSS via Bazar valeur Action
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
YesWiki before 4.6.7 contains a cross-site scripting vulnerability in the Bazar valeur action that allows page editors to inject script by rendering unescaped HTML fetched from a remote URL. Attackers can point tools/bazar/actions/valeur.php at a controlled server returning BAZ_fiche_titre markup with an img onerror handler, executing script in every viewer's browser.
