Last modified

CVE-2026-59807 is a high-severity vulnerability rated 8.9/10 on the CVSS scale. 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.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
