PatchSiren cyber security CVE debrief
CVE-2026-15462 gingerplugins CVE debrief
The Sticky Chat Widget plugin for WordPress is vulnerable to SQL Injection via the 'scw_form_fields' parameter array keys of the 'scw_save_form_data' AJAX action in versions up to, and including, 1.4.2. This vulnerability allows unauthenticated attackers to inject malicious SQL queries, potentially leading to data breaches or other security incidents. WordPress administrators and defenders should assess their exposure and prioritize verification and potential remediation. The vulnerability is caused by the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(), which wraps column identifiers in backticks without escaping them.

Who should care
WordPress administrators and defenders responsible for securing WordPress installations should assess exposure and prioritize verification and potential remediation. They should verify the presence of the vulnerable plugin version, assess exposure to potential SQL Injection attacks, and prioritize remediation or compensating controls if exposure is confirmed.
Why it matters
CVE-2026-15462 is a SQL Injection vulnerability in the Sticky Chat Widget plugin for WordPress. Defenders should prioritize verifying the presence of this vulnerability in their WordPress installations and assess exposure to potential SQL Injection attacks.
- Verify the presence of the vulnerable plugin version.
- Assess exposure to potential SQL Injection attacks.
- Prioritize remediation or compensating controls if exposure is confirmed.
Technical summary
The Sticky Chat Widget plugin for WordPress is vulnerable to SQL Injection via the 'scw_form_fields' parameter array keys of the 'scw_save_form_data' AJAX action in versions up to, and including, 1.4.2. This is due to the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(), which wraps column identifiers in backticks without escaping them, allowing a backtick in an attacker-supplied key to break out of the column-identifier list into raw SQL; additionally, the use of filter_input() bypasses WordPress's wp_magic_quotes() protection, and the widget_id validation loop is skipped entirely when no valid widget_id is supplied, leaving $isValid at 1.
Defensive priority
Defenders should prioritize verifying the presence of this vulnerability in their WordPress installations and assess exposure.
Recommended defensive actions
- Verify the presence of the Sticky Chat Widget plugin version 1.4.2 or earlier in your WordPress installation.
- Assess exposure by checking if the 'scw_form_fields' parameter is used in the 'scw_save_form_data' AJAX action.
- Consider upgrading to a patched version of the plugin, if available.
- Review compensating controls for exposed systems while remediation is scheduled and verified.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
Evidence notes
The vulnerability is due to the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(). The use of filter_input() bypasses WordPress's wp_magic_quotes() protection, and the widget_id validation loop is skipped entirely when no valid widget_id is supplied, leaving $isValid at 1. This allows a backtick in an attacker-supplied key to break out of the column-identifier list into raw SQL. The vulnerability can be exploited by unauthenticated attackers to append additional SQL queries into The
