Computer Emergency Response Team for EU institutions. URL CORRECTED 2026-05-08: /publications root is a navigation page only — sub-agents repeatedly returned a STUB. Drill into /publications/security-advisories/ (per-advisory entries with IDs like 2026-006) and /publications/threat-intelligence/ (monthly Cyber Briefs, e.g. cb26-05). Cite the per-advisory URL https://cert.europa.eu/publications/security-advisories/{YYYY-NNN}/ rather than the index.
