What is CVE-2026-8183?

IBM Langflow OSS versions 1.0.0 through 1.10.3 are susceptible to a directory traversal vulnerability. This issue allows an unauthenticated remote attacker to manipulate URL requests and exploit logical flaws in path validation. By utilizing specially crafted requests containing 'dot dot' sequences ('../'), the attacker can traverse the filesystem and potentially access sensitive files. This could lead to unauthorized information disclosure, posing a significant risk to the security of affected systems. Users are urged to update their installations as soon as patches are available.
