CVE-2023-35166Public exploitNetwork attack vector

Privilege escalation via unrestricted tip content rendering

Published Jun 20, 2023 · Updated Dec 6, 2024

Incorrect authorization in XWiki Platform allows remote authenticated users to execute arbitrary wiki content through a crafted tip extension. TipsPanel renders the tip parameter from an org.xwiki.platform.help.tipsPanel UI extension without a restricted transformation context, so macros run with the TipsPanel author's rights. An account able to create and save a UI extension can run Groovy code with those elevated rights, affecting confidentiality, integrity, and availability.
