CVE-2026-93587 - Vulnerability Details

- ImageMagick before 7.1.2-31 Policy Bypass via PCD decoder

Description

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.

Analysis

Impact

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD decoder. When a specific command line option is supplied, the decoder skips an enforced resource limit, leading to excessive memory allocation and a limited availability impact.

Affected Systems

ImageMagick versions before 7.1.2-31 and 6.9.13-56 are affected. The vulnerability impacts the ImageMagick:ImageMagick product as identified by the CNA.

Risk and Exploitability

The CVSS score of 4.8 signals moderate severity. The EPSS score of < 1% indicates a very low exploitation probability, and the vulnerability is not listed in CISA KEV. Exploitation requires local access to ImageMagick's command line; therefore the likelihood of widespread attacks is low, but organizations allowing local command execution should patch promptly to prevent potential denial of service.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade ImageMagick to version 7.1.2-31 or 6.9.13-56, which contain the fix for the policy bypass.
If an upgrade cannot be applied immediately, restrict local users from providing arbitrary command line options that trigger the PCD decoder, such as by disabling the decoder in the policy or removing its support.
Monitor image processing workloads for anomalous memory consumption and review logs for signs of excessive allocation that could indicate exploitation attempts.
