CVE-2026-17626: CWE-266 Incorrect Privilege Assignment in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.10.3 Langflow could allow an authenticated attacker to read, modify, or expose sensitive host files via Docker-based MCP servers due to incomplete filtering of dangerous Docker volume-mount and device-mapping arguments.
AI Analysis
Technical Summary
CVE-2026-17626 affects IBM Langflow OSS versions 1.0.0 through 1.10.3. The vulnerability arises from improper privilege assignment related to Docker volume-mount and device-mapping arguments, which are not fully filtered. This allows an authenticated attacker to potentially access, modify, or expose sensitive files on the host system via Docker-based MCP servers. The CVSS v3.1 score is 8.8, indicating a high severity with network attack vector, low attack complexity, and requiring low privileges but no user interaction. The impact includes confidentiality, integrity, and availability being fully compromised.
Potential Impact
An authenticated attacker can leverage this vulnerability to read, modify, or expose sensitive files on the host system running Docker-based MCP servers in IBM Langflow OSS. This compromises confidentiality, integrity, and availability of the host system's data and resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been provided at this time. Until a patch is available, restrict authenticated user privileges and monitor for suspicious activity related to Docker volume mounts and device mappings.
