CVE-2026-24481

ImageMagick has Possible Heap Information Disclosure in PSD ZIP Decompression

Published: 2/24/2026 Last updated: 2/26/2026 Reserved: 1/23/2026

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap information disclosure vulnerability exists in ImageMagick's PSD (Adobe Photoshop) format handler. When processing a maliciously crafted PSD file containing ZIP-compressed layer data that decompresses to less than the expected size, uninitialized heap memory is leaked into the output image. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
