CVE-2026-107507 Overview
CVE-2026-107507 is a broken access control vulnerability in the Squadeno WordPress plugin versions prior to 1.12.0. The plugin fails to enforce role-based restrictions consistently across all code paths that save sport records. Users holding the lowest-tier Trainer role can modify fields they should not control, including section, age group, author, password, comment settings, and the date of sports they are assigned to. The flaw is tracked under CWE-863: Incorrect Authorization.
Critical Impact
Authenticated Trainer-role users can tamper with sport records by bypassing authorization checks that exist on some save paths but not others.
Affected Products

Technical Details for CVE-2026-107507
Vulnerability Analysis
The Squadeno plugin exposes multiple code paths for saving sport records. Authorization checks are applied inconsistently across these paths. One or more save handlers skip the role-based restrictions enforced elsewhere in the plugin.
A Trainer, the lowest privilege role defined by the plugin, is intended to be limited to narrow updates on assigned sports. Because at least one save path omits those checks, a Trainer can submit modifications to protected fields: section, age group, author, password, comment settings, and the record date.
Exploitation requires an authenticated account and existing assignment to a sport record. The impact is limited to integrity of sport records; confidentiality and availability are not directly affected. The EPSS score places this issue in the lower risk tier for active exploitation prediction.
Root Cause
The root cause is incorrect authorization [CWE-863]. The plugin enforces role restrictions on the primary save routine but omits equivalent checks on alternative save handlers. This creates divergent trust boundaries for the same underlying data object.
Attack Vector
An authenticated attacker with the Trainer role sends a crafted request to a save endpoint that lacks field-level authorization. The request includes values for fields the Trainer should not control. The plugin accepts and persists the changes. See the WPScan Vulnerability Report for additional technical context.
Detection Methods for CVE-2026-107507
Indicators of Compromise
- Unexpected modifications to sport records attributed to Trainer-role accounts, especially changes to author, password, or date fields.
- Audit log entries showing POST requests to Squadeno save endpoints from low-privilege users containing restricted field parameters.
- Sport records whose author field no longer matches the originating editor or administrator.
Detection Strategies
- Review the WordPress audit trail for sport record changes made by non-administrative accounts.
- Compare current field values against backups to identify unauthorized modifications to protected attributes.
- Enable verbose logging on the Squadeno plugin endpoints and correlate request parameters with user role at request time.
Monitoring Recommendations
- Monitor HTTP requests to Squadeno plugin AJAX and REST endpoints for parameter sets that include restricted fields.
- Alert on any Trainer-role account submitting payloads containing author or password keys.
- Track version strings reported by the Squadeno plugin across managed WordPress sites to confirm patch adoption.
How to Mitigate CVE-2026-107507
Immediate Actions Required
- Upgrade the Squadeno plugin to version 1.12.0 or later on all WordPress sites.
- Audit sport records for unauthorized modifications made before the patch is applied.
- Review the Trainer role membership and remove accounts that are no longer required.
Patch Information
Upgrade to Squadeno 1.12.0 or later. The release enforces authorization checks across all save paths for sport records. Refer to the WPScan Vulnerability Report for the vendor fix reference.
Workarounds
- If immediate patching is not possible, temporarily revoke Trainer role assignments until the upgrade is applied.
- Restrict access to WordPress administrative endpoints using web application firewall rules that block requests containing restricted field parameters from non-administrative users.
- Disable the Squadeno plugin on sites where sport record integrity is critical and patching cannot be completed.
