Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Terminating idle connections bounds resource consumption that would otherwise allow uncontrolled accumulation of open sessions.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.

Deeper analysisAI
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.
