Preliminary research
CVE-2026-32740: RCE in a PIE Next.js sharp/libheif stack
AI-collected research leads through 3 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
This exploit chain turns a controlled libheif chroma-plane overflow in a Next.js sharp image path into a pointer leak, profiled stack identification, forged image-plane write and GOT hijack. It then redirects execution to load an uploaded shared object, with explicit Ubuntu and Debian profiles and regression checks.
