Summary

CVE-2026-59807 is a high-severity External Control of File Name or Path (CWE-73) vulnerability. Its CVSS base score is 8.9 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 21th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as AI Agent Protocols and Integrations; in the LLM/Generative AI Risks risk domain.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
