SCA: security update for com.cedarpolicy:cedar-java (GHSA-qmch-v2q9-wg4p)

high Tenable Self-Hosted Container Security Plugin ID 443597

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 Cedar-expression injection via unescaped toCedarExpr(). The
 toCedarExpr() method on Cedar Value types does not escape special characters (" or \) when converting
 values to Cedar source code. If an integrator uses toCedarExpr() to build policy text at runtime from
 user-controlled values, an actor could inject arbitrary Cedar expressions. For example, injecting || true
 into a permit ... when { ... } clause could make the permit unconditional, or injecting && false into a
 forbid clause could prevent the forbid from triggering. This issue requires the integrator to use
 toCedarExpr() to build policy text at runtime from user-controlled input. This vulnerability has been
 fixed in versions 2.3.6, 3.4.1, and 4.9.0. (CVE-2026-55773)

Solution

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