Coverity Connect Authentication Bypass via API

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-1496

Coverity Connect is a centralized platform for managing static analysis, typically accessible via a web interface or API for distributed teams. The vulnerability involves an API endpoint used for authentication. While not always exposed to the public internet, these management platforms are frequently deployed as network-accessible services to facilitate remote access for developers and automated CI/CD pipeline integration.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Coverity Connect, a tool used for managing code analysis. This issue allows an attacker to bypass authentication if they know or can guess a valid username, potentially granting them full access to the account and all its privileges. The primary concern is to confirm if this specific tool is in use and if it is exposed in a way that could be targeted.

  • Authentication bypass in code analysis tool.
  • Critical access gained by guessing usernames.
  • Confirm relevance and exposure of Coverity Connect.

Attack Path

How an attacker could exploit the issue

An attacker could bypass authentication to Coverity Connect by targeting its command-line tooling's authentication logic. If an attacker can reach the `/token` API endpoint and knows or guesses a valid username, they can send a specially crafted HTTP request to impersonate that user. This bypass allows the attacker to gain all the permissions and roles associated with the targeted Coverity Connect account.

  • Attacker needs access to the `/token` API endpoint.
  • Attacker crafts an HTTP request with a valid username.
  • Risk: Full account takeover and privilege escalation.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to bypass authentication and gain access to a Coverity Connect instance. When supported by the advisory, an attacker could exploit this by sending a specially crafted HTTP request to the `/token` API endpoint, provided they know or can guess a valid username. This could lead to unauthorized access with the privileges of the targeted user account.

  • Coverity Connect account privileges and roles.
  • Bypass authentication via crafted API request.
  • Unauthorized access and control of the system.

Operational Fix

Recommended remediation, mitigation, and detection steps

In real-world scenarios, ownership of Coverity Connect, particularly concerning its API security, likely falls to platform or infrastructure teams responsible for managing centralized development tools. Security teams may also be involved due to the authentication bypass and potential for privilege escalation. The first practical step is to identify all instances of Coverity Connect within the environment, determine their network reachability and business criticality, and then ascertain the accountable owner for each instance to initiate a risk-based remediation plan.

  • Platform or infrastructure teams own this.
  • Verify network exposure and critical systems.
  • Plan remediation based on identified risks.

Frequently asked questions

What is Coverity Connect?

Coverity Connect is a centralized platform used to manage static analysis results. Development teams rely on it to aggregate code quality data and track security findings across various projects. It provides a web interface and API endpoints that integrate into CI/CD pipelines, allowing distributed teams to access analysis reports and coordinate remediation efforts.

What does CVE-2026-1496 mean for security?

This vulnerability is an authentication bypass, classified as CWE-639. It occurs because the system lacks a proper error handler in the authentication logic for command-line tools. By interacting with a specific API, an attacker can trick the system into accepting an unauthorized request, effectively logging in as another user and assuming their full account privileges.

How does an attacker trigger this vulnerability?

An attacker must reach the /token API endpoint and provide a valid username. If the request is specially crafted, the system fails to verify credentials, completing the authentication process without a password. This does not trigger if the endpoint is unreachable or if the attacker cannot determine a valid username to target.

Is my Coverity Connect instance at risk?

Halo Surface Signal indicates that while these platforms are not always on the public internet, they are often reachable over internal networks to support automated CI/CD workflows. If your instance is accessible to untrusted network segments, it is more likely to be reachable by an attacker, increasing the potential impact of this authentication weakness.

What should I do first to address this?

Start by identifying every instance of Coverity Connect running in your environment. Once you have a complete inventory, verify the network reachability for each instance to understand which ones are exposed. Determine who manages these specific servers, then coordinate with those teams to assess business criticality and prioritize the necessary security updates.
