CVE-2022-29946
Description
A flaw was found in the NATS Server and NATS Streaming Server. Affected versions of this package could allow a remote attacker to bypass security restrictions due to a failure to enforce negative user permissions in one scenario. By using a queue subscription on the wildcard, an attacker could exploit this vulnerability to allow denied subjects.
Mitigation
Recraft user permission rules to only add access, never deny it.
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.
