CVE-2026-109278 - Vulnerability Details

- ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Memory Leak in Wavelet-Denoise Operation

Description

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the wavelet-denoise operation, which fails to release allocated memory when a required resource cannot be acquired. Attackers can repeatedly trigger wavelet-denoise processing under resource-constrained conditions to leak memory and degrade service availability.

Analysis

Impact

ImageMagick releases prior to 6.9.13-57 and 7.x prior to 7.1.2-32 contain a memory leak in the wavelet‑denoise operation. The flaw causes allocated memory to persist when a resource cannot be obtained, allowing an attacker to repeatedly trigger the operation under constrained conditions to consume memory and degrade service availability. This is a classic resource exhaustion issue classified under CWE‑401 and CWE‑772.

Affected Systems

ImageMagick ImageMagick versions 6.9.13‑56 and earlier, and 7.x versions before 7.1.2‑32 are vulnerable. Users running those releases should verify their installed version against the vendor’s release notes.

Risk and Exploitability

The CVSS score of 6.3 indicates medium severity. EPSS is not available, and the vulnerability is not listed in the CISA KEV catalog, implying no confirmed exploitation. The likely attack vector involves an attacker supplying or manipulating image data that triggers wavelet‑denoise on a server or application performing image processing. Repeated exploitation can gradually exhaust memory, leading to a denial of service for the affected process or the broader system.

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

Update ImageMagick to version 6.9.13‑57 or newer, or to 7.1.2‑32 or newer
If an immediate update is not possible, disable the wavelet‑denoise operation for untrusted images or contexts, or configure the application to execute image processing in a sandboxed process with strict memory limits
Monitor memory usage and process stability, and configure automated restarts or alerts to detect and recover from excessive memory consumption
