DescriptionGitHub Advisory

XWiki Full Calendar Macro displays objects from the wiki on the calendar. Prior to version 2.4.5, users with the right to view the Calendar.JSONService page (including guest users) can exploit a SQL injection vulnerability by accessing database info or starting a DoS attack. This issue has been patched in version 2.4.5.

AnalysisAI

XWiki Full Calendar Macro (before 2.4.5) has SQL injection accessible to guest users via the Calendar.JSONService page. Maximum CVSS 10.0 with scope change. Patch available.

Technical ContextAI

The Calendar.JSONService page processes user input in SQL queries without parameterization (CWE-89). Since the page is accessible to guest users (no login required), any visitor can exploit the injection. The scope change and max CVSS indicate impact beyond the wiki database.
