CVE-2026-22171 PUBLISHED

OpenClaw < 2026.2.19 - Path Traversal in Feishu Media Temporary File Naming

Assigner: VulnCheck
Reserved: 06.01.2026 Published: 18.03.2026 Updated: 18.03.2026

OpenClaw versions prior to 2026.2.19 contain a path traversal vulnerability in the Feishu media download flow where untrusted media keys are interpolated directly into temporary file paths in extensions/feishu/src/media.ts. An attacker who can control Feishu media key values returned to the client can use traversal segments to escape os.tmpdir() and write arbitrary files within the OpenClaw process permissions.
