criticalCVSS 9.8Vulnerability
GHSA-26w7-cxv4-gfx2
A vulnerability in `libheif`, used by the default Sharp image service in Astro, can lead to remote code execution when a malicious AVIF image is optimized. Projects are affected when an attacker can cause Astro to process an untrusted AVIF image. The fix was released in Astro 7.2.8, which requires Sharp 0.35.4.
