CVE-2026-59807: Composio SDK < 0.2.32-beta.283 - Sensitive File Upload via tool-file-uploads.ts

• Severity: medium (CVSS 6.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-08 · updated 2026-10-25
• Weakness: CWE-73

Description

Composio SDK before 0.2.32-beta.283 contains a path validation bypass vulnerability that allows attackers to read and exfiltrate sensitive files by exploiting a missing assertSafeFileUploadPath check in the readFileFromDisk function within tool-file-uploads.ts. Attackers can exploit prompt injection to manipulate file_uploadable parameters to reference sensitive paths such as SSH private keys, causing the CLI to upload credential files to attacker-controlled storage.
