VulnCheck reports that attackers are actively exploiting an unpatched flaw in Langflow, a popular open-source platform for building AI applications. The bug (CVE-2026-5027, rated 8.8) is a path-traversal weakness: the file-upload endpoint does not clean the supplied filename, so an attacker can use directory-climbing sequences to write files anywhere on the server, a foothold that leads to remote code execution. Tenable, which found it, says the maintainers did not respond after three contact attempts in early 2026, and there is still no official fix. Early exploitation appears to be probing, with attackers writing harmless test files, but that usually precedes heavier attacks.
CrowdStrike disclosed CVE-2026-40050 on April 21, a critical unauthenticated path traversal in a specific cluster API endpoint of self-hosted LogScale (formerly Humio). CVSS 9.8. A remote attacker who can reach the endpoint can read arbitrary files from disk - including config files, certificates, embedded credentials, and the very logs the platform was deployed to protect. CrowdStrike found the bug through internal product testing and applied network-layer blocks across all SaaS clusters on April 7. Self-hosted customers must patch themselves. There is no evidence of in-the-wild exploitation yet.
