Security readout for executives and security teams
Plain-English summary
CVE-2026-0816 affects the WordPress plugin “All push notification for WP” up to version 1.5.3. An attacker who already has administrator-level access could abuse a plugin parameter to read sensitive database information. This is not a remote unauthenticated issue, so urgency is lower than many SQL injection flaws, but exposed admin accounts increase risk.
Executive priority
Treat as a targeted cleanup item, not an emergency internet-wide fire drill. Prioritize sites where administrators are numerous, shared, or externally managed, and where the WordPress database contains sensitive customer or business data.
Technical view
The plugin is vulnerable to time-based SQL injection through the delete_id parameter because user input is not sufficiently escaped or prepared in an SQL query. CVSS 3.1 is 4.9 with high privileges required and high confidentiality impact. The issue is classified as CWE-89 and affects versions up to and including 1.5.3 per the CVE description.
Likely exposure
WordPress sites using All push notification for WP version 1.5.3 or earlier are the likely exposure. Exploitation requires an authenticated administrator or higher-privileged account, limiting exposure to compromised, malicious, or misused admin sessions.
Exploitation context
The provided sources do not state active exploitation, and the CVE is not listed as KEV in the supplied bundle. The practical risk is highest where WordPress administrator accounts are shared, weakly protected, or already compromised.
Researcher notes
Evidence is limited to the CVE/Wordfence description and WordPress Trac code references. The bundle does not name a patched version or confirm exploitation in the wild. Avoid assuming unauthenticated reachability; the stated prerequisite is administrator-level authentication.
Mitigation direction
- Inventory WordPress sites for the All push notification for WP plugin.
- Identify plugin versions and prioritize any installation at 1.5.3 or earlier.
- Check the plugin vendor, WordPress.org, and Wordfence guidance for an available fix.
- Restrict and monitor WordPress administrator access until remediation is confirmed.
- Remove the plugin if it is unnecessary and no trusted fix is available.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the installed plugin version from WordPress administration or asset inventory.
- Review administrator account activity for unusual plugin actions or database-related errors.
- Check web and application logs for suspicious requests involving delete_id.
- Verify remediation against vendor or WordPress.org release information.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
