CVE-2026-46693
Description
A flaw was found in ImageMagick. An attacker able to connect to a magick -distribute-cache service could exploit a race condition to hijack a file descriptor in the server process. This could lead to unauthorized access to sensitive information.
Statement
This flaw is rated as Low impact. It requires an attacker to have high privileges and the ability to connect to a magick -distribute-cache service. Exploitation is further limited by the high attack complexity and a race condition, making it difficult to reliably hijack a file descriptor for information disclosure. This service is not typically enabled or exposed by default in Red Hat products.
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.
