XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Users without the right to view documents can deduce their existence by repeated Livetable queries. The issue has been patched in XWiki 14.6RC1, 13.10.8, and 14.4.3, the response is not properly cleaned up of obfuscated entries. As a workaround, The patch for the document `XWiki.LiveTableResultsMacros` can be manually applied or a XAR archive of a patched version can be imported, on versions 12.10.11, 13.9-rc-1, and 13.4.4. There are no known workarounds for this issue.

GHSA-p2x4-6ghr-6vmq — Exposure of Sensitive Information to an Unauthorized Actor in org.xwiki.platform:xwiki-platform-livetable-ui

Affected: Maven: org.xwiki.platform:xwiki-platform-livetable-ui

### Impact

User without the right to view documents can deduce their existence by repeated Livetable queries.

#### Reproduction steps

1. Restrict "view" access to `Sandbox.TestPage3` by setting an explicit view right for admins 1. As a user who is not an admin, open `<server>/bin/get/XWiki/LiveTableResults?outputSyntax=plain&classname=&collist=doc.title%2Cdoc.location%2Cdoc.content&doc.title=Sandbo&doc.location=Sandbox.TestPage3&doc.content=dummy&limit=0` where `<server>` is the URL of your XWiki installation.

#### Expect Result:

No results are displayed as the user doesn't have view rights on Sandbox.TestPage3.

##### Actual Result:

The result

```json { "reqNo": null, "matchingtags": {}, "tags": [], "totalrows": 1, "returnedrows": 0, "offset": 1, "rows": [ { "doc_viewable": false, "doc_fullName": "obfuscated" } ] } ```

is displayed.

This reveals that a document `Sandbox.TestPage3` exists (we explicitly searched for this name) which has a title containing `"Sandbo"` and a content containing `"dummy"`. By starting with a single letter and then iteratively extending the match, the full content of the title/content or XObject properties can be discovered. Several tests can be combined in a single request to use binary search to narrow down the actual match from a list of possible characters/words. If the used alphabet is known and smaller than 128 distinct characters, it is possible to discover one character with 7 requests. Alternat…
