SCA: security update for com.cedarpolicy:cedar-java (GHSA-93g4-m6xv-cmvr)

high Tenable Cloud Security Plugin ID 443595

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - CedarJava is an open source Java implementation of the Cedar policy language, used for fine-grained
 authorization decisions. In versions prior to 2.3.6, 3.4.1 and 4.9.0, under certain circumstances,
 improper input handling could allow Record-to-Entity type confusion across the Java-Rust FFI boundary.
 CedarJava sends authorization requests to the Rust cedar-policy evaluator as JSON. The JSON protocol
 reserves magic single-key object shapes (__entity and __extn) for entity references and extension values.
 When serializing a CedarMap, there is no validation preventing these reserved keys from being used. If an
 integrating service builds a CedarMap from caller-supplied key/value data (such as request headers, user-
 defined metadata, or resource tags), an actor who controls those keys could cause the Rust evaluator to
 interpret a record as an entity reference. This issue requires the integrating service to build a CedarMap
 where the an actor controls the keys, and a policy must reference that value in a when/unless clause. This
 vulnerability has been fixed in versions 2.3.6, 3.4.1, and 4.9. (CVE-2026-55772)

Solution

Update the com.cedarpolicy:cedar-java library and its related packages to version 2.3.6 or later.
