CVE-2026-3003 describes a high-severity Stored Cross-Site Scripting (XSS) vulnerability in the Vagaro Booking Widget plugin for WordPress, affecting all versions up to 0.3. This flaw allows unauthenticated attackers to inject arbitrary web scripts via the 'vagaro_code' parameter due to insufficient input sanitization, which then execute when a user accesses an affected page. Rated with a CVSS v3.1 score of 7.2 (HIGH), the vulnerability is easily exploitable remotely without requiring user interaction or authentication, potentially leading to information disclosure or integrity compromise. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion, as reflected by its low EPSS score and lack of KEV listing.
