CVE-2026-30883
Published: 10 March 2026
Summary
CVE-2026-30883 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 5.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 0.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-30883 is a heap overflow vulnerability (CWE-119) in ImageMagick, a free and open-source software suite for editing and manipulating digital images. The issue arises when encoding a PNG image with an extremely large image profile, affecting all versions prior to 7.1.2-16 and 6.9.13-41. It was published on 2026-03-10 and carries a CVSS v3.1 base score of 5.7 (AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H), indicating medium severity with primary impacts on availability and limited integrity.
A local attacker can exploit this vulnerability by supplying a specially crafted image with an oversized profile to trigger the heap overflow during PNG encoding. No privileges or user interaction are required, but the attack demands high complexity and local access to the vulnerable ImageMagick instance. Successful exploitation could lead to high availability disruption, such as denial-of-service via application crash, and limited integrity violations, potentially allowing memory corruption without confidentiality impact or scope change.
The official ImageMagick GitHub security advisory (GHSA-qmw5-2p58-xvrc) confirms the vulnerability and states it is fixed in versions 7.1.2-16 and 6.9.13-41. Security practitioners should update to these patched releases immediately and validate image inputs to prevent processing of malformed profiles, especially in automated image processing pipelines.
