Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-8958 is an unrestricted file write and read vulnerability in the filetools actions of composiohq/composio version 0.4.3. The issue stems from improper validation of file paths, enabling attackers to access and modify files anywhere on the server. Published on 2025-03-20, it is associated with CWE-434 and carries a CVSS score of 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting critical severity due to high impacts on confidentiality, integrity, and availability.

Remote unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By manipulating file paths in filetools actions, they can read sensitive files or write arbitrary content, potentially achieving privilege escalation or remote code execution on the affected server.

Mitigation details are available in the advisory published on Huntr at https://huntr.com/bounties/e152b094-0593-428e-b813-068d2390ce68. Security practitioners should review this reference for patch information and remediation steps specific to composio version 0.4.3.

Mitigating Controls (NIST 800-53 r5) AI

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
