CVE-2026-40141 is a high-severity vulnerability in a web application component of BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA). The flaw is caused by insufficient validation of certain user-supplied input parameters. According to the provided content, an authenticated attacker with limited privileges, but possessing specific permissions, may be able to manipulate input in a way that allows access to unintended resources or data outside the attacker’s intended authorization scope. The issue affects RS and PRA versions 25.3.2 and earlier and is fixed in version 25.3.3 and later, as well as by the April 2026 Security Rollup for supported branches.
