Summary
CVE-2026-32554 is an unauthenticated SQL injection vulnerability in the WooBeWoo Product Filter Pro WordPress plugin (package woofilter-pro), affecting all versions up to and including 3.1.8. The flaw allows remote, unauthenticated attackers to inject malicious SQL through an unsanitized parameter, resulting in unauthorized read access to the underlying WordPress database. It carries a CVSS v3.1 base score of 9.3 (Critical).
Technical details
- Root cause: The plugin fails to properly sanitize and escape user-supplied input before using it in a SQL query (CWE-89: Improper Neutralization of Special Elements used in an SQL Command).
- Trigger conditions: No authentication or user interaction is required; an attacker can send a crafted request to a vulnerable plugin endpoint to trigger the injection.
- Attack vector: Network — the vulnerability is remotely exploitable over HTTP(S) against any internet-facing WordPress site running the affected plugin.
- Impact: Successful exploitation can lead to unauthorized disclosure of database contents (high confidentiality impact) and a limited availability impact; the scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component itself.
Affected software
- WooBeWoo Product Filter Pro (WordPress plugin, package
woofilter-pro) — all versions up to and including 3.1.8
Severity
- CVSS v3.1 Base Score: 9.3 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L
Mitigation and recommended actions
- Immediate: Upgrade WooBeWoo Product Filter Pro to a version released after 3.1.8 that addresses this SQL injection issue.
- If no patch is available/applied: Restrict or disable public access to the plugin’s vulnerable functionality, deploy a web application firewall (WAF) with SQL injection detection rules in front of the WordPress site, and monitor database and web server logs for anomalous query patterns until the plugin can be updated.
