CVE-2026-10167: OUSL-GROUP-BrinaryBrains School Student Management System MY_Controller Login.php sign_auth_cookie improper authentication
A weakness has been identified in OUSL-GROUP-BrinaryBrains School Student Management System up to 1e70e5ad1125b86dca4ee086eb6bb121f17708b6. This impacts the function sign_auth_cookie of the file application/controllers/Login.php of the component MY_Controller. Executing a manipulation of the argument role can lead to improper authentication. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.
Security readout for executives and security teams
Plain-English summary
This CVE affects a school student management system and may let a remote attacker bypass authentication by manipulating role handling during login cookie creation. The sources report public proof-of-concept availability, but CISA KEV is false and no cited source confirms active exploitation.
Executive priority
Treat this as high priority for schools or service providers using this application. Public exploit availability and missing vendor response increase operational risk, but affected footprint may be narrow and active exploitation is not confirmed.
Technical view
CVE-2026-10167 is CWE-287 improper authentication in application/controllers/Login.php, function sign_auth_cookie, within MY_Controller. Manipulation of the role argument can affect authentication decisions. VulDB rates it CVSS 7.5 under CVSS v2. Affected versioning is unclear because the project uses rolling releases.
Likely exposure
Exposure is likely limited to organizations running OUSL-GROUP-BrinaryBrains School Student Management System, especially internet-facing deployments at or before commit 1e70e5ad1125b86dca4ee086eb6bb121f17708b6. Version mapping and fixed release details are not available in the provided sources.
Exploitation context
The source bundle says exploitation can be remote and a public exploit exists. It does not establish active exploitation, and KEV is false. The project was reportedly notified through an issue but had not responded, leaving remediation status uncertain.
Researcher notes
Evidence is centered on VulDB, the CVE record, and a GitHub issue. The sources identify the function and role argument but do not provide a vendor fix, affected release range, or confirmed exploitation telemetry. Avoid assuming broader product families are affected.
Mitigation direction
Identify any deployed instances of this student management system.
Restrict public access to login surfaces until vendor guidance is available.
Monitor the GitHub issue, CVE record, and VulDB entry for fixes.
Update to a corrected upstream commit if one is published.
Review authentication cookie and role-handling logic before production use.
Validation and detection
Confirm whether deployed code includes commit 1e70e5ad1125b86dca4ee086eb6bb121f17708b6 or earlier.
Review application/controllers/Login.php for role-dependent authentication cookie decisions.
Check logs for unusual login activity or unexpected role changes.
Verify compensating controls restrict access to administrative login paths.
Track vendor response and document whether any fixed commit exists.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
