Deeper analysis
CVE-2026-1172 is a denial-of-service vulnerability (CWE-404) in birkir prime versions up to 0.4.0.beta.0. The affected component is an unknown function within the /graphql file of the GraphQL Directive Handler. Manipulation of this function leads to denial of service, with 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).
Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation results in low-impact availability disruption, causing denial of service without compromising confidentiality or integrity.
The project was notified early via GitHub issue #543 but has not responded. No patches or official mitigations are available. The exploit has been publicly disclosed and may be used, with details referenced in the birkir prime GitHub repository and VulDB entries (ctiid.341766, id.341766, submit.731103).
