MapLibre Vulnerability Exposes 2.7M Users to Zero-Click Attacks

Critical XSS CVE-2026-85061 in MapLibre GL JS enables zero-click attacks on an estimated 2.7 million users; fixed in maplibre-gl 6.4.1.

A flaw in MapLibre GL JS's DOM.sanitize() iterates a live NamedNodeMap while removing attributes, skipping malicious attributes placed adjacent to removed ones, letting event handlers like onload and ontoggle survive and execute via innerHTML in the attribution control. Tracked as CVE-2026-85061 and GHSA-jrc7-96c5-q579, the flaw affects maplibre-gl versions 6.4.0 and earlier, is rated critical under CVSS v3.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N), and requires no user interaction, privileges, or authentication. Exploitation could enable session theft, unauthorized actions, phishing redirects, or map content manipulation; the patch in 6.4.1 snapshots attributes with Array.from before iterating.

CVE-2026-82427: Apache Storm Nimbus: Path Traversal as the Supervisor User via Unsanitised Blobstore Map Local Name

Unsanitised topology.blobstore.map local names in Apache Storm enable path traversal writes on supervisors as the supervisor user.

CVE-2026-82427 affects Apache Storm Nimbus (org.apache.storm:storm-server) versions 3.0.0 before 3.1.0, rated important. Topology submitters can choose a local name for each blob in topology.blobstore.map, which AsyncLocalizer and Container.createBlobstoreLinks used to build paths under the topology's working directory without normalisation. Crafted names allow path traversal, letting a submitter create or overwrite files outside the intended directory on supervisors, with symlink handling also affected. Fixed in version 3.1.0.
