CVE-2023-34465: XWiki

High severity, CVSS 8.1. EPSS: 0.9% chance of exploitation in the next 30 days.

XWiki Platform is a generic wiki platform. Starting in version 11.8-rc-1 and prior to versions 14.4.8, 14.10.6, and 15.2, `Mail.MailConfig` can be edited by any logged-in user by default. Consequently, they can change the mail obfuscation configuration and view and edit the mail sending configuration, including the smtp domain name and credentials. The problem has been patched in XWiki 14.4.8, 14.10.6, and 15.1. As a workaround, the rights of the `Mail.MailConfig` page can be manually updated so that only a set of trusted users can view, edit and delete it (e.g., the `XWiki.XWikiAdminGroup` group).

Affected products

• XWiki XWiki: from 11.8.1, before 14.4.8 (fixed in 14.4.8); from 14.10, before 14.10.6 (fixed in 14.10.6); version 11.8 only; version 15.0 only
