CVE-2026-1175 is a medium severity vulnerability identified in birkir prime, an open-source or commercial software product, specifically affecting versions up to 0.4.0.beta.0. The vulnerability resides in an unspecified function within the GraphQL Directive Handler component, accessed via the /graphql endpoint. The issue causes information exposure through error messages generated by the system when processing crafted GraphQL requests. Because the attack vector is remote and requires no authentication or user interaction, an attacker can exploit this flaw to glean sensitive internal information such as system details, configuration data, or other metadata that should not be exposed. This information leakage can facilitate further targeted attacks or reconnaissance. The vulnerability has a CVSS 4.0 score of 6.9, reflecting a medium risk primarily due to its ease of exploitation (network accessible, no privileges needed) but limited impact confined to information disclosure without direct integrity or availability compromise. The vendor was notified early but has not yet responded or provided a patch, and while an exploit is publicly available, no confirmed active exploitation has been reported. The lack of a patch and public exploit availability increases the urgency for affected users to implement mitigations. The vulnerability highlights the importance of secure error handling in GraphQL APIs, which are increasingly used in modern web applications for flexible querying. Improper error message management can inadvertently reveal sensitive backend information, undermining security.

For European organizations, the primary impact of CVE-2026-1175 is the unintended disclosure of sensitive internal information through error messages in GraphQL APIs powered by birkir prime. This exposure can aid attackers in mapping internal infrastructure, identifying software versions, or uncovering configuration details, which can be leveraged for subsequent attacks such as privilege escalation, injection attacks, or targeted exploitation of other vulnerabilities. Sectors relying heavily on GraphQL APIs for critical services—such as finance, healthcare, telecommunications, and government—may face increased risk if birkir prime is part of their technology stack. The information leakage does not directly compromise data integrity or availability but weakens the overall security posture and increases the attack surface. Given the remote and unauthenticated nature of the exploit, attackers can probe vulnerable endpoints at scale, potentially affecting multiple organizations. The absence of a vendor patch means organizations must rely on compensating controls, increasing operational overhead. Additionally, compliance with European data protection regulations (e.g., GDPR) may be impacted if the exposed information includes personal or sensitive data, leading to legal and reputational consequences.

1. Immediately restrict access to the /graphql endpoint of birkir prime instances to trusted networks or authenticated users using network-level controls such as firewalls or API gateways. 2. Implement robust error handling and logging configurations to ensure that detailed error messages are not returned to clients; instead, return generic error responses that do not disclose internal details. 3. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious GraphQL queries that may trigger the vulnerability. 4. Monitor logs for unusual or repeated error message patterns that could indicate exploitation attempts. 5. If possible, disable or limit the use of the vulnerable GraphQL Directive Handler functionality until an official patch or update is released by the vendor. 6. Engage with the vendor or community to track patch releases and apply updates promptly once available. 7. Conduct internal security assessments and penetration tests focusing on GraphQL endpoints to identify similar information exposure risks. 8. Educate development and operations teams on secure GraphQL API design and error handling best practices to prevent future occurrences.
