CVE-2023-45137Public exploitNetwork attack vector

Stored XSS via unescaped existing-document reference

Published Oct 25, 2023 · Updated Sep 10, 2024

Stored cross-site scripting in XWiki Platform's create form allows remote authenticated users with edit rights to run script in another user's browser. The createinline.vm template inserts an attacker-chosen existingDocumentReference into a localized error message without XML escaping. An attacker must first create a nonempty document with a crafted name and induce a victim to reopen its creation form; the script then acts with the victim's rights.
