Security readout for executives and security teams

This issue affected old avast! Antivirus versions that gave all local users broad permissions over important files in the antivirus installation folder. A person with local access could potentially tamper with the product, weaken protection, or gain higher privileges. The bundle does not provide a CVSS score or confirmed active exploitation. Exposure is likely limited to legacy Windows systems still running avast! Antivirus 4.6.763 or earlier. Modern supported deployments are not identified in the supplied bundle, and affected CPE data is not provided. Treat as a legacy endpoint hygiene issue with meaningful local risk. Prioritize if affected systems still exist on shared workstations, servers, or regulated environments where antivirus integrity matters. Mitigation focus: Identify and remove or upgrade avast! Antivirus 4.6.763 and earlier installations.; Check Avast guidance for fixed versions or supported remediation steps.; Restrict local user access on affected systems until resolved..
