CVE-2023-51445

Summary

CVE-2023-51445 is a stored cross-site scripting (XSS) vulnerability affecting versions prior to 2.23.3 and 2.24.0 of GeoServer, an open-source Java-based geospatial software server. The flaw allows authenticated administrators with workspace-level privileges to inject malicious JavaScript code into uploaded style/legend resources. This code will execute in the context of another administrator's browser when viewing the affected resources through the REST Resources API. Access to this API is typically limited to full administrators, but granting access to non-administrators may lead to exposure of sensitive information. Version 2.23.3 and 2.24.0 include a patch to address this issue.
