CVE-2025-5897Public exploitNetwork attack vector

Build denial of service via icon-link regex

Published Jun 9, 2025 · Updated Jun 10, 2025

Regular expression denial of service in Vue CLI 5.0.8 and earlier allows attackers controlling project HTML to stall PWA builds. HtmlPwaPlugin applies an icon-link expression that repeatedly rescans long sequences of incomplete link tags, consuming excessive CPU. Reachability requires control of build input, and a Vue CLI maintainer disputes exploitability because plugin users already fully control that HTML.
