Summary

CVE-2024-8952 is a high-severity SSRF (CWE-918) vulnerability in Composio Composio. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Validates user-supplied URLs at the WEBTOOL_SCRAPE_WEBSITE_CONTENT endpoint to block crafted inputs targeting internal files, AWS metadata, or local services.

AC-4 Information Flow Enforcement good match

prevent

Enforces flow control policies restricting the endpoint's requests to authorized external destinations only, preventing SSRF access to internal resources.

SC-7 Boundary Protection partial match

preventdetect

Provides boundary protection through egress filtering and monitoring to block or identify SSRF-induced connections to localhost or metadata services.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

attack.mitre.org →

T1552.005 Cloud Instance Metadata API Credential Access

Adversaries may attempt to access the Cloud Instance Metadata API to collect credentials and other sensitive data.

Why these techniques?

SSRF in public-facing /api endpoint directly enables T1190; facilitates local file reads (T1005) and AWS instance metadata access (T1552.005).

NVD Description

A Server-Side Request Forgery (SSRF) vulnerability exists in composiohq/composio version v0.4.2, specifically in the /api/actions/execute/WEBTOOL_SCRAPE_WEBSITE_CONTENT endpoint. This vulnerability allows an attacker to read files, access AWS metadata, and interact with local services on the system.

Deeper analysisAI

CVE-2024-8952 is a Server-Side Request Forgery (SSRF) vulnerability, mapped to CWE-918, affecting composiohq/composio version v0.4.2. The flaw exists specifically in the /api/actions/execute/WEBTOOL_SCRAPE_WEBSITE_CONTENT endpoint. Published on 2025-03-20, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting high confidentiality impact from network-accessible exploitation with low complexity and no privileges or user interaction required.

An unauthenticated remote attacker can exploit this SSRF vulnerability by sending crafted requests to the affected endpoint. This enables the attacker to read arbitrary files on the server, access AWS instance metadata services, and interact with other local services running on the host system.
