Deeper analysis

XWiki, an open-source wiki platform, is affected by an authorization vulnerability (CWE-863) in its App Within Minutes application feature. Any user granted edit rights on at least one such application—the default permission level for all users—can escalate to programming rights through application editing, resulting in remote code execution on the server.

An attacker with standard edit access can modify an App Within Minutes application to obtain programming privileges, allowing arbitrary code execution and full compromise of the XWiki instance without requiring additional authentication or user interaction.

The issue has been resolved in XWiki versions 17.0.0, 16.4.7, and 16.10.3, according to the project's security advisory and the referenced commit that addresses the improper authorization checks. The EPSS score has remained flat at 0.0925 with no material increase observed since disclosure.
