Coverity Connect Authentication and Authorization Bypass.

CVE advisorySeverity: CRITICAL (CVSS 9.2)

CVE-2026-8338

Coverity Connect is a centralized platform for managing static analysis results. While it is a web-based application reachable over a network, it is typically deployed within internal development environments, behind firewalls, or on restricted corporate networks rather than being exposed directly to the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability has been identified in Coverity Connect, allowing unauthenticated actors to bypass access controls and view internal data through specially crafted requests. This issue affects specific versions of the software, which is used for managing static analysis results. The primary concern is to determine if your organization utilizes these affected versions and is potentially exposed.

Unauthenticated access to sensitive API data.
Critical for verifying if your environment is at risk.
Confirm relevance and assess potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker could bypass authentication and authorization controls on specific API endpoints by sending a crafted HTTP request. This bypass allows unauthorized access to sensitive data within Coverity Connect.

Unauthenticated access to network.
Crafted HTTP request targets API endpoints.
Bypass leads to unauthorized data access.

Specially crafted HTTP requests.
Unauthorized data access.

Operational Fix

Recommended remediation, mitigation, and detection steps

The security of Coverity Connect, a platform for managing static analysis results, requires attention from teams responsible for application security and infrastructure. The first practical step is to locate all instances of Coverity Connect, assess their network exposure and business criticality, and identify the accountable owners. This will enable a risk-based remediation plan, which may involve coordination with vendors or temporary mitigation strategies.

AppSec and Infrastructure teams own this.
Verify Coverity Connect reachability and criticality.
Plan remediation based on confirmed risk.

Frequently asked questions

What is Coverity Connect?

Coverity Connect is a centralized software platform used by development teams to manage, store, and analyze the results of static analysis scans. It acts as a hub for security and quality data, allowing teams to track code issues, prioritize remediation tasks, and maintain visibility over the codebase health throughout the development lifecycle.

What is the vulnerability in CVE-2026-8338?

This CVE describes an authentication and authorization bypass, classified as CWE-288. In plain terms, the system fails to correctly verify the identity of a user or their permissions before granting access. Because of this flaw in Spring Security controls, an unauthenticated person can send a specifically formatted HTTP request to certain API endpoints and potentially retrieve sensitive information from the application without ever logging in.

How does an attacker trigger this bypass?

An attacker triggers this flaw by sending a specially crafted HTTP request that targets specific API endpoints within the Coverity Connect software. It is important to note that this is not a general failure of the entire web interface; the bypass only functions on particular API endpoints, and success generally relies on the attacker being able to craft the request to manipulate how the underlying security logic processes authentication.

Is my instance of Coverity Connect at risk?

According to Halo Surface Signal, risk depends on your deployment. While Coverity Connect is a network-accessible web application, it is typically hosted within internal development environments, behind firewalls, or on restricted corporate networks. Instances that are accidentally exposed directly to the public internet face a much higher risk than those isolated from external traffic, which complicates an attacker's ability to reach these specific API endpoints.

What should I do if I run Coverity Connect?

First, identify all deployed instances of Coverity Connect within your infrastructure and confirm their exact version numbers to see if they fall within the 2023.6.0 to 2026.3.0 range. Once identified, map out the network reachability for each instance to determine if they are exposed to untrusted networks. Coordinate with your application security or infrastructure teams to prioritize these assets and prepare for vendor-supplied updates or temporary access restrictions.
