Security readout for executives and security teams
Plain-English summary
CVE-2026-25576 affects ImageMagick before 7.1.2-15 and 6.9.13-40. A crafted image-processing case can make ImageMagick read beyond a heap buffer. The main stated risk is information disclosure, not system takeover. Public sources name patched versions, and there is no provided evidence of active exploitation.
Executive priority
Treat this as a moderate-priority patching item. It is not currently documented as actively exploited, but affected image-processing services may handle untrusted files at scale. Prioritize internet-facing or customer-upload pipelines, then standardize patched ImageMagick versions in base images and application dependencies.
Technical view
The issue is a heap buffer over-read in multiple ImageMagick raw image coders when processing cases where -extract dimensions exceed -size dimensions. The CVSS 3.1 score is 5.1, with high confidentiality impact and no integrity or availability impact. The advisory says versions 7.1.2-15 and 6.9.13-40 contain the patch.
Likely exposure
Exposure is most likely where ImageMagick processes raw image formats, especially in automated image pipelines or applications accepting untrusted image inputs. Systems running ImageMagick 7.x before 7.1.2-15 or 6.x before 6.9.13-40 are in scope based on the provided advisory.
Exploitation context
No active exploitation is indicated by KEV or the provided sources. The CVSS vector is local, high complexity, no privileges required, and no user interaction. The described impact is out-of-bounds heap memory reading, which could expose sensitive process memory under specific processing conditions.
Researcher notes
The public description calls this a heap buffer over-read, while the CVE data maps CWE-122. Do not infer a write primitive from the CWE alone. The key boundary condition is extract dimensions larger than size dimensions in raw coders. The provided sources identify patched versions but do not provide alternate mitigations.
Mitigation direction
- Upgrade ImageMagick 7.x to 7.1.2-15 or later.
- Upgrade ImageMagick 6.x to 6.9.13-40 or later.
- Review vendor guidance for packaged or embedded ImageMagick builds.
- If using Magick.NET, review the referenced 14.10.3 release notes.
- Prioritize patching systems that process untrusted image files.
Validation and detection
- Inventory installed ImageMagick versions across servers, containers, and developer workstations.
- Check application dependencies for bundled or wrapper-provided ImageMagick copies.
- Identify workflows processing raw image formats or using extract and size options.
- Confirm patched versions are deployed after package or container updates.
- Monitor vendor advisories for any revised impact or workaround guidance.

Heap-based Buffer Overflow
Heap-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
