This is due to missing nonce validation in the ls_parse_vcita_callback() function. This makes it possible for unauthenticated attackers to modify the plugin's settings and inject malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-352"],"references":["https://blog.jonh.eu/blog/security-vulnerabilities-in-wordpress-plugins-by-vcita","https://plugins.trac.wordpress.org/browser/event-registration-calendar-by-vcita/trunk/system/parse_vcita_callback.php#L55","https://plugins.trac.wordpress.org/browser/paypal-payment-button-by-vcita/trunk/system/parse_vcita_callback.php","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3215558%40paypal-payment-button-by-vcita%2Ftrunk&old=2965959%40paypal-payment-button-by-vcita%2Ftrunk&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/207b40fa-2062-48d6-990b-f05cbbf8fb8e?source=cve"],"products":["vcita:event_registration_calendar_by_vcita","vcita:online_payments_-_get_paid_with_paypal\\,_square_\\&_stripe"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-2407","score":0.00419,"percentile":0.36231,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
