CVE-2023-36471Public exploitNetwork attack vector

Administrator-triggered code execution via allowed form controls

Published Jun 29, 2023 · Updated Nov 26, 2024

Injection in XWiki Commons 14.6-rc-1 through 14.10.5 and 15.0-rc-1 through 15.1 allows remote authenticated users to execute code. HTMLDefinitions allowlists form, input, select, textarea, and button elements in restricted mode, so a hidden content field can carry Groovy markup into an edit submission. The attacker needs document-editing access, and code executes only after an administrator submits the crafted sheet form.
