GHSA-wq5f-xc86-pv6w
HIGHA memory-related vulnerability has been discovered and fixed in the upstream librsvg dependency. When certain runtime-specific conditions apply, this vulnerability can lead to possible remote code execution (RCE) on glibc-based Linux.
// using prebuilt binaries provided by sharp?Most people rely on the prebuilt binaries provided by sharp.
Please upgrade sharp to the latest version, currently 0.35.5, which provides librsvg 2.63.2.
// using a globally-installed librsvg?Please ensure you are using the latest librsvg 2.63.2.
// workaroundsAdd the following to your code to prevent sharp from decoding SVG images.
sharp.block({ operation: ["VipsForeignLoadSvg"] });To avoid RCE, ensure you are using a node executable binary compiled as a Position Independent Executable (PIE). Most Linux package managers already use this security-hardening feature however be warned that the "official" Node.js binaries do not. 1
