{"schemaVersion":3,"id":"CVE-2024-12077","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Booking Calendar and Booking Calendar Pro plugins for WordPress are vulnerable to Reflected Cross-Site Scripting via the ‘calendar_id’ parameter in all versions up to, and including, 3.2.19 and 11.2.19 respectively, due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.","dates":{"published":"2025-01-07T07:22:33.559Z","modified":"2026-04-08T17:03:49.073Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00378,"percentile":0.30505,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.009999999999999983,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00368},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00378,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00378,"percentile":0.30505}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00368,"percentile":null},{"date":"2026-10-07T00:00:00.0
