    TrendAI said it patched CVE-2026-34926 in Apex One after the zero-day was exploited in the wild. The medium-severity directory traversal flaw affects only the on-premises version, requires admin credentials to the server, and could let an attacker modify a key table and inject malicious code to deploy to agents on affected installations. TrendAI also said its incident response team discovered the vulnerability internally, and CISA added CVE-2026-34926 to the KEV catalog with a June 4 remediation deadline for federal agencies.
