In IZArc through 4.5, there is a Mark-of-the-Web Bypass Vulnerability. When a user performs an extraction from an archive file that bears Mark-of-the-Web, Mark-of-the-Web is not propagated to the extracted files. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content.
Conclusion & alert: CVE-2025-46652 is rated Moderate Risk (41.9/100): CVSS Medium severity, with low exploitation likelihood (EPSS 0.26%).Mandatory action: Review affected assets and schedule remediation.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
