    Loading SGLang's Nemotron image processor sets Pillow's MAX_IMAGE_PIXELS to None, so the decompression-bomb guard is off process-wide. Five CVEs from VulnCheck (@VulnCheckAI), no fix, none exploited. https://severitydaily.com/sglang-cve-2026-109225-109229-nemotron-max-image-pixels-none-process-wide-no-fixed-release/
