Summary

CVE-2026-1169 is a medium-severity CSRF (CWE-352) vulnerability in Birkir Prime. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 10th 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 map to AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-1169, published on 2026-01-19, is a cross-site request forgery (CSRF) vulnerability in birkir prime versions up to 0.4.0.beta.0. The issue affects unknown code within the software and is associated with CWE-352 (Cross-Site Request Forgery) and CWE-862 (Missing Authorization). It has a CVSS v3.1 base score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N), indicating medium severity with network accessibility, low attack complexity, no privileges required, user interaction needed, unchanged scope, no confidentiality or availability impact, and low integrity impact.

Attackers can exploit this vulnerability remotely without authentication by tricking users into performing unintended actions on a trusted site, typically via a malicious webpage or link that submits forged requests. Exploitation requires user interaction, such as clicking a link or visiting a site while authenticated to the affected birkir prime instance, potentially leading to unauthorized state changes due to the low integrity impact.

References indicate the vulnerability was reported early to the project via GitHub issue #547 at https://github.com/birkir/prime/issues/547, but the maintainers have not responded. No patches or specific mitigations are detailed in the advisories from VulDB (https://vuldb.com/?ctiid.341763, https://vuldb.com/?id.341763, https://vuldb.com/?submit.731287). The exploit has been publicly disclosed and may be used; practitioners should monitor the repository at https://github.com/birkir/prime/ for updates and consider CSRF protections like tokens in the interim.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 directly requires enforcement of authorization decisions on every access request, structurally eliminating missing authorization checks.

AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.

AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.

AC-6 reduces the set of actions reachable without proper authorization, limiting blast radius of missing checks.

Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.

prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

finds

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

prevents

Defining authorization responsibilities and reviewing risk-treatment progress throughout the project lifecycle catches missing authorization checks before the system is deployed.
