CVE-2026-56367 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contains an integer overflow in the PSB (PSD v2) RLE decoding path (ReadPSDChannelRLE in coders/psd.c) that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash.. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
