CrowdStrike has released security updates to address a critical unauthenticated path traversal vulnerability (CVE-2026-40050) in LogScale. This vulnerability only requires mitigation by customers that host specific versions of LogScale and does not affect Next-Gen SIEM customers. The vulnerability exists in a specific cluster API endpoint that, if exposed, allows a remote attacker to read arbitrary files from the server filesystem without authentication. Next-Gen SIEM customers are not affected and do not need to take any action. CrowdStrike mitigated the vulnerability for LogScale SaaS customers by deploying network-layer blocks to all clusters on April 7, 2026. We have proactively reviewed all log data and there is no evidence of exploitation. LogScale Self-hosted customers should upgrade to a patched version immediately to remediate the vulnerability. CrowdStrike identified this vulnerability during continuous and ongoing product testing.

A logic error exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors. There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence teams are actively monitoring for exploitation and we maintain visibility into any such attempts. The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this. CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed.
