CVE-2023-50720: XWiki Platform Solr search discloses email addresses of users
First published: Fri Dec 15 2023(Updated: )
### Impact The Solr-based search in XWiki discloses the email addresses of users even when obfuscation of email addresses is enabled. To demonstrate the vulnerability, search for `objcontent:email*` using XWiki's regular search interface. ### Patches This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1 by not indexing email address properties when obfuscation is enabled. Further, changing the setting now triggers re-indexing of the affected wiki(s). ### Workarounds We're not aware of any workarounds. ### References * https://jira.xwiki.org/browse/XWIKI-20371 * https://github.com/xwiki/xwiki-platform/commit/3e5272f2ef0dff06a8f4db10afd1949b2f9e6eea ### Attribution This vulnerability was reported on Intigriti by [ynoof](https://twitter.com/ynoofAssiri) @Ynoof5.
