    MapLibre GL JS: XSS Sanitizer Bypass in DOM.sanitize() via Live NamedNodeMap Removal Skip

    CVE-2026-85061 · GHSA-jrc7-96c5-q579

    Affected
    • npm maplibre-gl <= 6.4.0
    Fixed in
    6.4.1· Vendor fix available
    Issue
    Impact DOM.sanitize() in src/util/dom.ts iterated elem.attributes (a live NamedNodeMap) while calling elem.removeAttribute() in the same loop. Removing an attribute shifts subsequent attributes down by one index, causing the iterator to skip the adjacent attribute. An attacker can provide an HTML payload with consecutive dangerous attributes (such as <details open onload="1" ontoggle="..."). The first attribute is stripped while the second survives and executes upon insertion into innerHTML via the attribution control without requiring user interaction (zero-click XSS). Applications rendering untrusted/third-party style attribution strings or user-supplied custom attributions are impacted. Patches The issue has been resolved by creating a static snapshot of attributes using Array.from(elem.attributes) before iteration. Please upgrade to maplibre-gl version 6.4.1 (or latest). Workarounds Sanitizing the attribute field of a source before passing it down to maplibre

    Recommended action: Upgrade to 6.4.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
