This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires a separately installed plugin, such as Contact Form 7, that passes unauthenticated user-controlled input into mail fields whose content PHPMailer will include in its failure error message.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/wp-mail-catcher/tags/2.1.12/src/Loggers/LogHelper.php#L69","https://plugins.trac.wordpress.org/browser/wp-mail-catcher/tags/2.1.12/src/Loggers/WpMail.php#L30","https://plugins.trac.wordpress.org/browser/wp-mail-catcher/tags/2.1.12/src/MailAdminTable.php#L149","https://plugins.trac.wordpress.org/browser/wp-mail-catcher/tags/2.1.12/src/Views/LogModal.php#L83","https://plugins.trac.wordpress.org/changeset?reponame=&old=3717442%40wp-mail-catcher&new=3717442%40wp-mail-catcher"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-93889","score":0.00241,"percentile":0.15082,"date":"2026-10-25"},"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).
