CVE-2026-17609

Summary

The flaw allows unauthenticated attackers to recursively delete arbitrary directories on the server, including the WordPress root directory, due to insufficient validation of JSON field declarations and a bypassable ABSPATH guard.

Exploitability

Exploitation is relatively straightforward if the 'Delete files from server after form submissions' setting is enabled, requiring an attacker to craft a malicious form submission.

Blast radius

If exploited, the attack could result in the complete loss of the WordPress installation and potentially other server files, leading to significant service disruption and data loss.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the 'Delete files from server after form submissions' setting immediately. If this setting cannot be disabled, upgrade to version 6.3.32 or later.
