GHSA-gg53-wf5x-r3r6 XWiki Platform Security Parent POM vulnerable to overwriting of security rules of a page with a final page having the same reference

• Maven org.xwiki.platform:xwiki-platform-security: >= 5.0, < 12.10.11 → fixed in 12.10.11 • Maven org.xwiki.platform:xwiki-platform-security: >= 13.0, < 13.4.6 → fixed in 13.4.6 • Maven org.xwiki.platform:xwiki-platform-security: >= 13.10, < 13.10.1 → fixed in 13.10.1

Impact A bug in the security cache is storing rules associated to document Page1.Page2 and space Page1.Page2 in the same cache entry. That means that it's possible to overwrite the rights of a space or a document by creating the page of the space with the same name and checking the right of the new one first so that they end up in the security cache and are used for the other too. Patches The problem has been patched in XWiki 12.10.11, 13.10.1, 13.4.6. Workarounds No workaround other than patching.
