CVE-2026-105083
Description
A flaw was found in ImageMagick. A local attacker with permission to modify the security policy configuration file can bypass defined security restrictions by supplying an alternate XML document type declaration (DOCTYPE). Due to improper parsing of certain DOCTYPE declarations, the configuration parser consumes the remainder of the file and silently fails to load security rules. As a result, restricted or forbidden operations are permitted to execute.
Statement
This vulnerability is rated as having a Low impact because an attacker would need elevated privileges on the host to introduce an alternate DOCTYPE format into the security policy file, diminishing the practical risk of unauthorized privilege escalation.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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.
