CVE-2025-30215
Description
A flaw was found in NATS-SERVER. In affected versions of NATS-SERVER, the management of JetStream assets happens with messages in the $JS. subject namespace in the system account; this is partially exposed into regular accounts to allow account holders to manage their assets. Some JS API requests were missing access controls, allowing any user with JS management permissions to perform specific administrative actions on any JS asset in any account. At least one of the unprotected APIs allows data to be deleted. This issue does not restrict who can perform specific administrative tasks on someone else's JetStream assets. None of the affected APIs allow disclosing stream contents.
Statement
The Trusted Profile Analyzer guac container is not affected by this vulnerability as guac is used without NATS and NATS is not installed with the product.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
Access control checks for specific user data or functionality can be bypassed.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Horizontal escalation of privilege is possible (one user can view/modify information of another user).
Access Control
Technical Impact: Gain Privileges or Assume Identity
Vertical escalation of privilege is possible if the user-controlled key is actually a flag that indicates administrator status, allowing the attacker to gain administrative access.
