TrueConf Client carries the only CISA KEV-confirmed, actively exploited CVE in this rollup period: CVE-2026-3502, a CWE-494 integrity check failure in the client update mechanism (CVSS 7.5, KEV deadline April 16, 2026). Exploitation requires network positioning between the client and update infrastructure and results in arbitrary code execution via a tampered update payload, a high-impact outcome given the trusted context of software update processes. Immediate actions are to disable auto-update, block TrueConf updater outbound connections to unverified endpoints, and apply the vendor patch as soon as TrueConf publishes a confirmed fixed version — fixed version numbers are not yet available in NVD or CISA data and must be verified against the official TrueConf security advisory before deployment.
