CVE-2026-40105

Estado: AnalizadaMedia (6.5)—

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 10.4-rc-1, through 16.10.15, 17.0.0-rc-1, through 17.4.7 and 17.5.0-rc-1 through 17.10.0 contain a reflected cross-site scripting vulnerability (XSS) in the comparison view between revisions of a page allows executing JavaScript code in the user's browser. If the current user is an admin, this can not only affect the current user but also the confidentiality, integrity and availability of the whole XWiki instance. If developers are unable to update immediately, they can apply the patch manually to templates/changesdoc.vm in the deployed WAR.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
