In composiohq/composio version 0.4.3, there is an unrestricted file write and read vulnerability in the filetools actions. Due to improper validation of file paths, an attacker can read and write files anywhere on the server, potentially leading to privilege escalation or remote code execution.
Executive ViewAI
Organizations using composiohq/composio face critical risk from CVE-2024-8958, a unrestricted file upload vulnerability rated CVSS 9.8. This could allow attackers to access or modify files outside intended directories, potentially exposing sensitive configuration or credentials. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Restrict file upload functionality via WAF; (2) Implement allowlist-based file type validation; (3) Use chroot/containerization to limit filesystem access.

What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
