CISA KEV Advisory
7-Zip Mark of the Web Bypass Vulnerability
7-Zip contains a protection mechanism failure vulnerability that allows remote attackers to bypass the Mark-of-the-Web security feature to execute arbitrary code in the context of the current user.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This vulnerability in 7-Zip involves a protection mechanism failure that allows remote attackers to bypass the Mark-of-the-Web security feature. This bypass can lead to arbitrary code execution in the context of the current user. The high EPSS score of 0.33817 and its inclusion in CISA's KEV catalog indicate a significant and confirmed exploitation risk.
This vulnerability is being actively exploited in the wild and is listed in CISA's KEV catalog, confirming its active use by threat actors. The nature of the flaw suggests it can be exploited remotely, likely through specially crafted files.
Users should update 7-Zip to the latest patched version as soon as updates become available. Exercise caution when opening untrusted files, even if they appear to have security markings.
Technical Analysis
CVE-2025-0411 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-0411 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
