CVE-2026-56377: ImageMagick - Policy Bypass via Incorrect Path Validation

Noroxi assessment

Priority: Monitor (action score 19/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: ImageMagick ImageMagick 6.9.13-48, 7.1.2-24.

Low priority for now. Upgrade to ImageMagick ImageMagick 6.9.13-48, 7.1.2-24 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

ImageMagick before 7.1.2-24 contains an incorrect policy check that allows attackers to create or truncate files disallowed by security policies. Remote attackers can bypass path policy restrictions in sandboxed conversion services to write arbitrary files outside intended boundaries.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
