The Experto Dashboard for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's

The Experto Dashboard for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's settings fields (including 'Navigation Font Size', 'Navigation Font Weight', 'Heading Font Size', 'Heading Font Weight', 'Text Font Size', and 'Text Font Weight') in all versions up to and including 1.0.4. This is due to insufficient input sanitization (no sanitize callback in register_setting()) and missing output escaping (no esc_attr() in the field_callback() printf output) on user-supplied values. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in the plugin settings page that will execute whenever a user accesses the settings page.

This only affects multi-site installations and installations where unfiltered_html has been disabled.

▸ How to read a CVE - triage first, then detect and patch

This page is every public fact about CVE-2026-3574, cross-linked. Its job is to answer one question fast - does this need my attention now? - and then hand you the two things you do about it. Here is how an analyst reads it.

Triage: should I act now? Four signals, and they are not interchangeable:

CVSSseverity - how bad it is IF exploited, 0-10. A high CVSS alone is not urgency; a flaw can be a perfect 10 and never actually be attacked. EPSSprobability - a model’s estimate of the chance it is exploited in the next 30 days, 0-1. This is the “will it actually happen” signal. CISA KEVconfirmed - it is being exploited in the wild right now. The strongest signal on the page; KEV beats any score. Weaponisedavailability - public exploits / PoCs, and especially Metasploit modules rated Excellent / Great. Reliable, packaged exploit code means low-skill attackers can use it today.

How they combine: KEV, or a dependable Metasploit module, means patch now regardless of CVSS. High CVSS + low EPSS + no exploit is real but not an emergency - schedule it. Low CVSS but KEV-listed still gets patched now. The verdict above already weighed these for you; this is how it got there.

Then what - two workflows:

Detectwhen you cannot patch today, follow this CVE to the ATT&CK techniques it enables, then Build a SIEM detection (the green button) - author a rule, test it in Atomic, deploy it. That buys visibility while the patch waits. PatchAffected products / packages tell you if you are exposed; Fixed versions by distribution and Vendor advisories give the exact version that closes it.

Reading order for the panels below: verdict + badges, then Public exploits / Metasploit (is it weaponised), then ATT&CK techniques + Sigma / IDS rules (can I detect it), then Affected products / packages + Fixed versions (am I exposed, what patches it), then Threat actors / IOCs (who uses it), then Scoring & timeline / references (the evidence).
