CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:LSummary
CVE-2026-53466 is a medium-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 6.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 13th 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 SI-2 (Flaw Remediation) and RA-5 (Vulnerability Monitoring and Scanning) — see the control section below for these in your framework.

Vulnerability Data
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-51 and 7.1.2-26, an integer overflow in the XCF decoder can result in an out of bounds read when a crafted image is read,…

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires timely application of the vendor patch that eliminates the integer overflow in the XCF decoder.
Mandates validation of image inputs before decoding, which can reject malformed XCF files that trigger the overflow.
Requires scanning to discover instances of the vulnerable ImageMagick versions before exploitation occurs.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
