FKIE_CVE-2026-105083

Vulnerability from fkie_nvd - Published: 2026-10-03 02:17 - Updated: 2026-10-03 02:17
Severity
3.9 (Low) - CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:L
Summary
ImageMagick before 7.1.2-32 and 6.9.13-57 contains a policy bypass vulnerability in LoadPolicyCache that silently skips security policy rules when policy.xml uses an alternate DOCTYPE. A valid DOCTYPE not ending in ']>' makes the parser consume the rest of the file, so no policy rules are applied and restricted operations become allowed.
