CVE-2026-24128Network attack vectorHinoki check available

Victim-privilege actions via unescaped extension identifiers

Published Jan 23, 2026 · Updated Jan 23, 2026

Reflected XSS in XWiki Platform allows remote attackers to act with a victim's privileges after the victim opens a crafted URL. The logging_macros.vm template inserts a missing extension identifier into extension-link HTML without applying XML escaping, allowing markup in the identifier to reach the response. Exploitation requires victim interaction; the resulting actions remain bounded by that victim's rights, although administrative or programming rights grant full installation access.
