Overview
Affected versions of this package are vulnerable to Information Exposure in the processing of JEXL expressions when the JexlContextBuilder name denylist can be bypassed with a one-hop navigation. An attacker can obtain sensitive information from linked accounts or managers by crafting malicious JEXL expressions if they have sufficient entitlements for reading user data. This is only exploitable if an administrator with adequate entitlements for Derived Schemas creates a malicious JEXL expression.
