Summary

CVE-2026-28693 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 26th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-28693 is an integer overflow vulnerability in the DIB coder of ImageMagick, a free and open-source software suite for editing and manipulating digital images. The flaw affects ImageMagick versions prior to 7.1.2-16 and 6.9.13-41, where improper handling of image data can lead to out-of-bounds read or write operations. It is associated with CWE-125 (Out-of-bounds Read), CWE-190 (Integer Overflow or Wraparound), and CWE-787 (Out-of-bounds Write), and carries a CVSS v3.1 base score of 8.1 (High).

The vulnerability can be exploited remotely over a network by unauthenticated attackers (PR:N) without requiring user interaction (UI:N), though it demands high attack complexity (AC:H) and does not change the scope (S:U). Successful exploitation enables high-impact consequences, including unauthorized disclosure of sensitive information (C:H), modification of data or system integrity (I:H), and denial of service via availability disruption (A:H), such as through memory corruption.

The ImageMagick security advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-hffp-q43q-qq76 confirms the issue and states that it is fixed in versions 7.1.2-16 and 6.9.13-41. Security practitioners should update to these patched releases to mitigate the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.

SC-39 Process Isolation partial match

Process isolation confines the effects of an out-of-bounds read to the compromised process.

SI-10 Information Input Validation partial match

Input validation rejects malformed indices or lengths that would otherwise cause reads outside buffer bounds.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

PR.PS-06 mostly match
prevents

Secure-development practices such as bounds checking and memory-safe languages directly prevent out-of-bounds reads.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover instances of out-of-bounds reads after code is deployed.

PR.PS-02 partial match
prevents

Routine patching replaces vulnerable code containing out-of-bounds read flaws.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

A.8.26 Application security requirements partial match
prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
