Cross-site scripting via clobbered currentScript lookup
Published Aug 27, 2024 · Updated Jan 9, 2025
Cross-site scripting in webpack 5 before 5.94.0 allows remote attackers to execute JavaScript through crafted scriptless HTML. AutoPublicPathRuntimeModule trusts document.currentScript without confirming that it is a SCRIPT element, allowing a named IMG to supply an attacker-controlled chunk URL. Exploitation requires an automatic or unset public path and a consuming page that admits attacker-controlled name or id attributes; successful attacks execute script in that page.
