Spring AI: Insufficient Validation causes SSRF when processing multimodal messages with user-supplied URLs

High severity GitHub Reviewed Published Mar 27, 2026 to the GitHub Advisory Database • Updated Mar 29, 2026

Package

maven org.springframework.ai:spring-ai-bedrock-converse (Maven)

Affected versions

>= 1.0.0-M5, < 1.0.5

Patched versions

1.0.5
1.1.4

Description

Spring AI's spring-ai-bedrock-converse contains a Server-Side Request Forgery (SSRF) vulnerability in BedrockProxyChatModel when processing multimodal messages that include user-supplied media URLs. Insufficient validation of those URLs allows an attacker to induce the server to issue HTTP requests to unintended internal or external destinations.

This issue affects Spring AI: from 1.0.0 before 1.0.5, from 1.1.0 before 1.1.4.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Server-Side Request Forgery (SSRF)

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Learn more on MITRE.
