CVE-2026-0816 in All push notification for WP Plugin
Summary
by MITRE • 02/04/2026
The All push notification for WP plugin for WordPress is vulnerable to time-based SQL Injection via the 'delete_id' parameter in all versions up to, and including, 1.5.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The vulnerability identified as CVE-2026-0816 affects the All push notification for WP plugin, a widely used WordPress extension for managing push notifications. This security flaw exists in versions up to and including 1.5.3, representing a significant risk to WordPress installations that rely on this plugin for notification services. The vulnerability stems from inadequate input validation and sanitization practices within the plugin's codebase, specifically in how it handles user-supplied data during the deletion process. The affected parameter 'delete_id' lacks proper escaping mechanisms, creating an avenue for malicious exploitation that could compromise the entire WordPress installation.
The technical implementation of this vulnerability follows a classic time-based SQL injection pattern where an attacker can manipulate the SQL query execution flow through the 'delete_id' parameter. This flaw falls under CWE-89, which categorizes SQL injection vulnerabilities as a direct result of insufficient input sanitization and improper query construction. The vulnerability requires authentication with administrator-level privileges or higher, making it particularly dangerous as it leverages existing administrative access to escalate privileges and extract sensitive data from the underlying database. The time-based nature of the injection allows attackers to infer information through response timing differences, making the exploitation more stealthy and difficult to detect through standard monitoring systems.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to execute arbitrary SQL commands within the database context. This could lead to complete database compromise, allowing unauthorized access to user credentials, personal information, and potentially sensitive business data stored within the WordPress installation. The vulnerability affects all WordPress installations using the affected plugin version, making it a widespread concern for website administrators who may not be aware of their specific plugin versions. Additionally, the time-based nature of the injection means that detection becomes more challenging as the attack patterns are less obvious than traditional SQL injection techniques.
Mitigation strategies for CVE-2026-0816 should prioritize immediate plugin updates to the latest available version that contains the necessary security patches. System administrators should implement strict access controls and monitor user activities for any suspicious behavior related to notification management functions. The vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and privilege escalation, as the attack requires administrative access but could lead to further system compromise. Organizations should also consider implementing database query monitoring and logging to detect anomalous SQL execution patterns that may indicate exploitation attempts. Regular security audits and vulnerability assessments should include checking for outdated plugins and ensuring all WordPress components are running the most current secure versions to prevent similar vulnerabilities from being exploited in the future.
