AI-suggested

The vendor has indicated the issue has been fixed by restricting property access in the JEXL sandbox, but no explicit patch or remediation level is provided in the available data. Users should monitor Sonatype advisories for an official fix and apply it once available. Until then, restrict the nexus:selectors:create permission to trusted users only.

Description

Nexus Repository 3 did not fully sandbox JEXL expressions used in Content Selectors. An account holding the nexus:selectors:create permission could construct an expression that read Java object properties not intended to be exposed to the expression engine, disclosing internal JVM class metadata such as class and classloader names. This issue does not permit method invocation, object construction, or arbitrary code execution. This has been fixed by restricting property access in the JEXL sandbox to the intended data types.
