Last modified

CVE-2026-109229 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. SGLang through 0.5.21 contains a denial of service vulnerability that disables Pillow decompression bomb protection process-wide by setting Image.MAX_IMAGE_PIXELS to None in NanoNemotronVLImageProcessor. Remote attackers can submit small, highly compressed images with huge dimensions to the generic image loader, exhausting worker memory during decoding.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
