This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation requires at least one File-type custom field to be published on the confirmation page shortcode, as this field is not created by default during plugin installation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/controllers/confirmapp.php#L88","https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/helpers/libraries/customfields/types/file.php#L131","https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/helpers/libraries/customfields/types/file.php#L53","https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/vikappointments.php#L237","https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.21/site/controllers/confirmapp.php#L88"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-87115","score":0.00899,"percentile":0.59378,"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).
