Operationally, ranked in the top 7.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Periodic review and update of procedures reduces incorrect authorization implementations over time.
Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.
Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.
Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.
Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.
Ensures authorization decisions for external system use are correctly implemented and enforced.
