CVE-2022-25759Public exploitNetwork attack vector

JavaScript execution via unsanitized SVG onload handler

Published Jul 22, 2022 · Updated Sep 16, 2024

Code injection in Neocotic convert-svg-core before 0.6.2 allows remote attackers to execute JavaScript through crafted SVG input. Converter.js embeds the supplied SVG into a Puppeteer/Chromium page without removing its onload attribute, so the browser runs the handler during conversion. Reachability requires a consuming application to pass attacker-controlled SVG data into the library; the published proof of concept reads a local file into the rendered image.
