What happened
Week-in-review covering multiple security developments: a Cisco Catalyst SD-WAN 0-day (CVE-2026-20245) is being actively exploited with no vendor patch available; exploitation requires netadmin credentials or prior compromise (CVE-2026-20182/CVE-2026-20127). Dashlane disclosed a brute-force attack that allowed an actor to copy encrypted user vaults (no evidence of internal system compromise). Let’s Encrypt announced work on post-quantum Merkle Tree Certificates (MTCs) targeted for staging in late 2026. Anthropic released analysis showing AI is enabling lower-skill actors to carry out advanced攻
