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.

addresses: CWE-862

Requiring an access control policy ensures authorization checks are defined and applied for critical functions.

addresses: CWE-862

Reviews of access controls detect missing authorization checks on critical functions or resources.

addresses: CWE-862

Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.

addresses: CWE-862

Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.

addresses: CWE-862

Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.

addresses: CWE-862

Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.

addresses: CWE-862

The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.

addresses: CWE-862

Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Deeper analysisAI

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).
