CVE-2026-67211: Apache OpenNLP: OOM DoS via Unbounded Array Allocation in SymSpellModelSerializer

Apache OpenNLP CVE-2026-67211: unbounded map pre-sizing in SymSpellModelSerializer enables out-of-memory denial of service in opennlp-symspell 3.0.0-M4/M5.

CVE-2026-67211 affects the opennlp-symspell artifact in versions 3.0.0-M4 and 3.0.0-M5 only.

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.
