CVE-2026-24481
HIGH
ImageMagick has Possible Heap Information Disclosure in PSD ZIP Decompression
Published February 24, 2026Updated February 24, 2026Source: osv
Summary
### Description
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.
### Expected Impact
Information disclosure leading to potential exposure of sensitive data from server memory.
