CVE-2026-1170: Medium Vulnerability in Birkir Prime

A vulnerability was detected in birkir prime up to 0.4.0.beta.0. This issue affects some unknown processing of the file /graphql of the component GraphQL API. Performing a manipulation results in information disclosure. The attack may be initiated remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

With a CVSS score of 5.5, this vulnerability is categorized as medium severity. Organizations should be aware that the potential risk involves unauthorized information disclosure, which could lead to further exploitation if not addressed in a timely manner.

Given that the exploit is public, organizations using affected versions of Birkir Prime should prioritize their response. The urgency is heightened as attackers may leverage this vulnerability to gain sensitive information.

Immediate action is recommended to mitigate any potential risks associated with this vulnerability.

Vulnerability Details

This vulnerability allows for information disclosure due to insufficient protection in the GraphQL API component of Birkir Prime. The official CVE description outlines that the manipulation of the /graphql file can lead to unauthorized access to sensitive information. The CVSS score of 5.5 signifies a medium severity level, reflecting the potential impact on confidentiality without affecting integrity or availability.

The affected product is Birkir Prime, with the vulnerability affecting all versions prior to the latest patch. The weakness is categorized under CWE-200 (Information Exposure) and CWE-284 (Improper Access Control). The publication date of this vulnerability is January 19, 2026.

Technical Analysis

The root cause of this vulnerability stems from improper handling of the GraphQL API requests, which allows attackers to manipulate the request structure. The attack vector is network-based, enabling remote exploitation with low attack complexity. No privileges or user interactions are required for exploitation, making this vulnerability particularly concerning.

In terms of impact, the confidentiality is rated as low since the vulnerability primarily allows for information disclosure without affecting data integrity or availability.

Risk & Impact Analysis

Risk to organizations includes potential exposure of sensitive data through the GraphQL API, which may lead to further attacks if exploited. The blast radius can extend to any organization using the affected versions of Birkir Prime, with the potential for attackers to leverage disclosed information for unauthorized access or further exploit vulnerabilities within the environment.

Given the medium severity and public exploit availability, organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.

Exploitation Status

Affected Versions

All versions prior to vendor patch are affected. Specifically, the vulnerability impacts Birkir Prime versions up to 0.4.0.beta.0.

Mitigation & Remediation

Organizations should implement the patch for Birkir Prime as soon as it becomes available. If immediate patching is not possible, consider disabling the GraphQL API or implementing additional access controls to limit exposure. Regularly review configurations and monitor for unauthorized access attempts.
