CVE-2026-15464 — WP Hotel Booking <= 2.3.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'widget_search' Shortcode Attribute

The WP Hotel Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'widget_search' Shortcode Attribute in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable on browsers where access keys can be used as the payload is stored in a hidden attribute.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
