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.

EchelonGraph scoreLOW confidence
This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
