Summary
by MITRE • 07/29/2026
A Spring Security authentication and authorization bypass exists in Coverity Connect versions between 2023.6.0 and 2026.3.0. An unauthenticated malicious threat actor that can send a specially crafted HTTP request is able to bypass authentication and authorization controls on certain API endpoints to access data within Coverity.

This vulnerability represents a critical authentication and authorization bypass in Coverity Connect software, affecting versions from 2023.6.0 through 2026.3.0. The flaw allows unauthenticated threat actors to craft specific HTTP requests that circumvent the intended security controls, enabling unauthorized access to protected data within the system. Such a vulnerability fundamentally undermines the security posture of any organization relying on Coverity Connect for code analysis and security monitoring. The issue stems from improper validation of authentication tokens or session management mechanisms within the application's API endpoints, creating a pathway for malicious actors to gain access without proper credentials.
The technical implementation of this bypass likely involves exploiting weaknesses in the Spring Security framework integration, potentially through manipulation of request parameters, headers, or authentication flow sequences. This type of vulnerability falls under CWE-287 which addresses improper authentication issues, and may also relate to CWE-306 which covers missing authentication checks. The attack vector specifically targets API endpoints that should require proper authentication before granting access to sensitive data or functionality. Threat actors can leverage this weakness to perform unauthorized operations including but not limited to data exfiltration, system enumeration, or potential lateral movement within the affected environment.
The operational impact of this vulnerability extends beyond simple unauthorized data access, as it compromises the integrity and confidentiality of security monitoring processes that Coverity Connect provides. Organizations utilizing this software may experience exposure of sensitive source code analysis results, security findings, and potentially proprietary information that should remain protected. The vulnerability affects the core security architecture of the platform, undermining trust in the system's ability to enforce access controls. According to ATT&CK framework, this represents a privilege escalation technique under T1078 which covers valid accounts usage, and may also involve T1566 for initial access through application vulnerabilities.
Mitigation strategies should focus on immediate patching of affected versions to address the authentication bypass mechanism. Organizations must ensure comprehensive testing of the patched environment to verify that all API endpoints properly enforce authentication requirements. Network segmentation and monitoring of API traffic can help detect unusual access patterns that might indicate exploitation attempts. Additional controls including rate limiting, IP whitelisting for administrative endpoints, and enhanced logging of authentication attempts should be implemented as temporary measures while permanent fixes are deployed. Regular security assessments of the Spring Security implementation within the application environment will help identify similar vulnerabilities in other components of the system architecture.
