CVE-2026-10285: DevaslanPHP Auth Bypass Vulnerability

CVE-2026-10285 Overview

CVE-2026-10285 is an improper authorization vulnerability [CWE-266] in the DevaslanPHP project-management application up to version 2.0.0-beta1. The flaw resides in the KanbanScrumHelper::recordUpdated function within app/Helpers/KanbanScrumHelper.php, part of the Ticket Handler component. An authenticated remote attacker can manipulate ticket update operations to perform actions outside their authorization scope. The vendor was notified through a public issue report but has not responded at the time of disclosure.

Critical Impact
Authenticated remote attackers can modify ticket records they should not have permission to alter, undermining project integrity and access control boundaries within the Kanban/Scrum workflow.

Affected Products

DevaslanPHP project-management up to and including 2.0.0-beta1
Component: Ticket Handler (app/Helpers/KanbanScrumHelper.php)
Function: KanbanScrumHelper::recordUpdated

Technical Details for CVE-2026-10285

Vulnerability Analysis

The vulnerability is classified under [CWE-266] Incorrect Privilege Assignment, a category of broken access control. The recordUpdated method in KanbanScrumHelper.php processes updates to Kanban/Scrum ticket records without enforcing sufficient authorization checks. As a result, authenticated users can trigger ticket update logic affecting resources they should not be entitled to modify.

The issue is exploitable over the network and requires only low privileges, meaning any account that can authenticate to the application is sufficient. No user interaction is required to trigger the flawed code path. Successful exploitation produces limited impact on integrity and availability of ticket data, with no direct confidentiality consequence reported.

Root Cause

The root cause is missing or insufficient authorization enforcement within the KanbanScrumHelper::recordUpdated helper. The function trusts the calling context to have validated the actor's permission against the target record, but that validation is absent or incomplete. This permits horizontal privilege escalation across tickets and projects within the same instance.

Attack Vector

An attacker authenticates to a vulnerable DevaslanPHP project-management instance using any valid low-privilege account. The attacker then issues crafted HTTP requests to the Kanban or Scrum board endpoints that invoke recordUpdated, referencing ticket identifiers belonging to other users or projects. Because the helper does not verify the actor's relationship to the target record, the update proceeds. No exploit code is publicly available, but the relevant source file is open and the issue has been documented in GitHub Issue Tracker #141.

Detection Methods for CVE-2026-10285

Indicators of Compromise

Unexpected ticket state transitions or field modifications in Kanban/Scrum logs attributed to users without project membership.
HTTP POST or PATCH requests targeting ticket update routes containing record identifiers outside the requesting user's assigned projects.
Database audit entries showing updated_by values inconsistent with the project's authorized member list.

Detection Strategies

Review application access logs for ticket update requests where the authenticated user identifier does not match expected project membership.
Correlate user session data with ticket ownership records to identify cross-tenant or cross-project update activity.
Inspect any custom audit logging around KanbanScrumHelper::recordUpdated invocations for anomalous source accounts.

Monitoring Recommendations

Enable verbose request logging on Kanban/Scrum API endpoints and forward logs to a centralized analytics platform.
Establish baselines for normal per-user ticket modification rates and alert on deviations.
Track GitHub project activity and the upstream DevaslanPHP project-management repository for vendor remediation commits.

How to Mitigate CVE-2026-10285

Immediate Actions Required

Restrict network access to DevaslanPHP project-management instances using VPN, IP allowlisting, or reverse proxy authentication until a patch is released.
Audit existing user accounts and remove or downgrade any that do not require active project access.
Review historical ticket modification logs for evidence of unauthorized updates predating discovery.

Patch Information

No official patch is available. According to the VulDB entry for CVE-2026-10285, the project was informed through a public issue report but has not responded. Track the vendor repository and GitHub Issue Tracker #141 for remediation status.

Workarounds

Apply a local code modification to app/Helpers/KanbanScrumHelper.php that validates the authenticated user has permission to modify the target ticket before recordUpdated performs persistence.
Place the application behind a web application firewall configured to block ticket update requests that reference identifiers outside the authenticated user's session scope.
Disable or limit Kanban/Scrum modification endpoints to administrative users until a vendor fix is available.

bash

# Example: restrict access to project-management ticket endpoints via nginx
location ~ ^/api/(tickets|kanban|scrum)/ {
    allow 10.0.0.0/8;       # internal corporate network
    deny  all;
    proxy_pass http://project_management_backend;
