Yes. CISA added CVE-2026-20700 to the Known Exploited Vulnerabilities catalog on 12 Feb 2026, which means there is reliable evidence of exploitation in the wild.
CISA does not list known ransomware use for it. That can change, and exploitation alone is reason to fix it first.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Check Apple's advisory for the fixed versions, and if you can't patch quickly, restrict access to the affected Multiple Products and watch it for signs of compromise.
