CVE-2023-34465 is a critical missing authorization vulnerability in Xwiki Xwiki, published on 23 Jun 2023. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description 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).

If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
