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.
