Which versions of Composio SDK are affected by EUVD-2026-42377?

Composio SDK CLI (@composio/cli) contains a critical path-traversal vulnerability allowing attackers to exfiltrate sensitive credentials (SSH keys, API tokens) by manipulating AI agent prompts.. A patch is available.

How to fix or mitigate EUVD-2026-42377?

Within 24 hours: Audit deployed @composio/cli versions; restrict or disable file-upload functionality if not operationally critical; implement prompt input validation to block path traversal patterns. Within 7 days: Deploy Web Application Firewall or agent-level filtering to block suspicious file_uploadable parameters; rotate all credentials (SSH keys, API tokens) that may have been accessible to affected systems. Within 30 days: Deploy patched @composio/cli version 0.2.32-beta.283 or later when released; conduct forensic audit of logs for unauthorized file access to sensitive directories.

DescriptionCVE.org

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.

AnalysisAI

Sensitive file exfiltration in Composio SDK (the @composio/cli package) before 0.2.32-beta.283 lets attackers steal credential files by abusing a missing path-safety check in the readFileFromDisk function of tool-file-uploads.ts. Because the assertSafeFileUploadPath guard is absent, an attacker who can influence the agent's prompt can manipulate file_uploadable parameters to point at arbitrary paths such as ~/.ssh private keys, causing the CLI to upload those files to attacker-controlled storage. There is no public exploit identified at time of analysis, but the upstream fix, issue, and pull request are all public, which lowers the bar for reproduction.
