Loading vulnerability…
image-size through version 2.0.2 contains an infinite-loop denial-of-service vulnerability in its JXL and HEIF image parsers. When parsing a recognized box type whose size field is zero, the parser does not advance its offset, causing the parsing loop to execute indefinitely. A remote attacker can supply a crafted image buffer to trigger this condition and block the Node.js event loop.

A denial-of-service vulnerability in the JXL and HEIF parsers of the npm image-size package. A crafted image containing a recognized box with a zero-valued size field causes the parser offset not to advance, resulting in an infinite loop that permanently blocks the Node.js event loop.
A denial-of-service vulnerability in image-size through 2.0.2 where crafted JXL or HEIF image data with a zero-sized box can trigger an infinite loop and hang the Node.js event loop.
