In short

XWiki's tag feature fails to properly filter user input, allowing attackers with basic view access to run malicious code that can read, modify, or delete all wiki content and bypass security controls.

Technical detail

Eval injection vulnerability in XWiki Platform Tag UI (CWE-94, CWE-95) allows authenticated or unauthenticated users to execute arbitrary Groovy, Python, and Velocity code via unsanitized input in the Main.Tags document, bypassing authorization checks and achieving complete compromise. When combined with CVE-2022-36092 on versions prior to 13.10.4/14.2, no authentication is required.

Summary generated and translated by AI from the official description.
XWiki Platform Applications Tag and XWiki Platform Tag UI are tag applications for XWiki, a generic wiki platform. Starting with version 1.7 in XWiki Platform Applications Tag and prior to 13.10.6 and 14.4 in XWiki Platform Tag UI, the tags document `Main.Tags` in XWiki didn't sanitize user inputs properly. This allowed users with view rights on the document (default in a public wiki or for authenticated users on private wikis) to execute arbitrary Groovy, Python and Velocity code with programming rights. This also allowed bypassing all rights checks and thus both modification and disclosure of all content stored in the XWiki installation. The vulnerability could be used to impact the availability of the wiki. On XWiki versions before 13.10.4 and 14.2, this can be combined with CVE-2022-36092, meaning that no rights are required to perform the attack. The vulnerability has been patched in versions 13.10.6 and 14.4. As a workaround, the patch that fixes the issue can be manually applied to the document `Main.Tags` or the updated version of that document can be imported from version 14.4 of xwiki-platform-tag-ui using the import feature in the administration UI on XWiki 10.9 and later.
