CVE-2026-107507 in Squadeno Plugin
Summary
by MITRE • 10/11/2026
The Squadeno WordPress plugin before 1.12.0 does not enforce its restrictions on every way a sport can be saved, allowing users with the lowest-tier Trainer role to change the section, age group, author, password, comment settings and date of a sport they are assigned to.

The vulnerability identified in Squadeno WordPress plugin versions prior to 1.12.0 represents a critical failure in access control mechanisms, specifically manifesting as an insecure direct object reference combined with insufficient authorization checks on the backend API endpoints responsible for saving sports data. In typical web application architectures, role-based access control is designed to restrict specific actions based on the user's assigned privileges within the system. However, this implementation flaw allows users possessing the lowest-tier Trainer role to bypass these restrictions entirely when interacting with the sport management functionality. The core technical issue lies in the server-side logic which fails to validate whether the authenticated user has sufficient permissions to modify all fields associated with a specific sports record during the save operation.
From a technical perspective, this vulnerability enables unauthorized modification of sensitive metadata and configuration attributes that should be restricted to higher-privileged roles such as Administrators or Coaches. Specifically, an attacker can alter the section and age group assignments, effectively manipulating how content is categorized and displayed within the application's hierarchy. More critically, the ability to change the author field allows for identity spoofing or attribution manipulation, which compromises data integrity and audit trails. The capability to modify password settings introduces a severe risk of account compromise if these fields relate to associated user accounts or administrative access points linked to the sports entity. Furthermore, altering comment settings can disrupt community engagement features or expose private discussions, while modifying dates allows for temporal manipulation that could affect scheduling, event validity, and historical records within the platform.
The operational impact of this vulnerability is significant as it undermines the fundamental security model of the WordPress ecosystem by allowing low-privilege users to perform administrative-level actions. This leads to a complete breakdown in data integrity, where critical information can be altered without proper oversight or approval workflows. Attackers with Trainer credentials could potentially escalate their influence within the application by manipulating content structure and metadata, leading to potential defacement, misinformation dissemination, or disruption of services for other users who rely on accurate scheduling and categorization of sports events. Additionally, if password fields are linked to user authentication mechanisms, this flaw could facilitate unauthorized access to associated accounts, further escalating the risk profile from mere data tampering to full account takeover scenarios.
This vulnerability aligns with CWE-269 Improper Privilege Management, as it involves a failure to enforce proper authorization levels for specific actions. It also maps closely to CWE-862 Missing Authorization, where the application does not verify that the user is authorized to perform the requested action on the specific resource. In terms of offensive security frameworks, this behavior corresponds to MITRE ATT&CK technique T1078 Valid Accounts, specifically within the context of local account manipulation and privilege escalation through misconfigured permissions. The exploitation vector typically involves crafting HTTP requests with modified parameters for fields that should be read-only or restricted for the Trainer role, sending them to the plugin's save endpoint without triggering any server-side rejection due to insufficient privileges.
To mitigate this vulnerability, immediate action is required by upgrading the Squadeno WordPress plugin to version 1.12.0 or later, where these access control restrictions have been properly enforced across all saving operations. Administrators should also implement strict input validation and authorization checks on the backend for every field being updated during a save request, ensuring that only users with appropriate roles can modify sensitive attributes like authorship, passwords, and system settings. Regular security audits of custom WordPress plugins are recommended to identify similar patterns where frontend role restrictions are not mirrored by robust server-side enforcement. Additionally, implementing principle of least privilege in the application's design ensures that even if a vulnerability exists, its impact is contained within minimal operational boundaries.
