Summary
CVE-2026-1174 is a medium-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Birkir Prime. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 45.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-1174 is a vulnerability in the birkir prime project, affecting versions up to 0.4.0.beta.0. It targets an unknown function within the /graphql endpoint of the GraphQL Alias Handler component, enabling resource consumption. Classified under CWE-400 (Uncontrolled Resource Consumption) and CWE-404, the issue has a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L), indicating medium severity with low impact on availability but no effects on confidentiality or integrity.
Remote attackers require no privileges, authentication, or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation results in partial denial of service through resource exhaustion, disrupting service availability for affected instances.
Advisories from VulDB note that the project was informed early via GitHub issue #545 but has not responded or released patches. The primary references include the birkir prime GitHub repository and VulDB entries detailing the issue (ctiid.341768, id.341768, submit.731105), with no mitigation guidance provided beyond awareness.
The exploit has been publicly disclosed and may be utilized, increasing the risk for unpatched deployments.
