This is due to missing file extension and content validation in the saveLiveImages() function combined with an insufficient authorization check on the get_keys() AJAX handler and a missing authentication check on the REST API import endpoint. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-434"],"references":["https://plugins.trac.wordpress.org/browser/real-estate-listing-realtyna-wpl/tags/5.3.0/api/init.php#L8","https://plugins.trac.wordpress.org/browser/real-estate-listing-realtyna-wpl/tags/5.3.0/libraries/idx/addon_idxn.php#L562","https://plugins.trac.wordpress.org/browser/real-estate-listing-realtyna-wpl/tags/5.3.0/libraries/idx/idx_property_mapper.php#L392","https://plugins.trac.wordpress.org/browser/real-estate-listing-realtyna-wpl/tags/5.3.0/views/backend/addon_idx/wpl_ajax.php#L238","https://www.wordfence.com/threat-intel/vulnerabilities/id/4a64f840-8570-4f98-8b72-27bee1607fc2?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-16236","score":0.012,"percentile":0.68184,"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).
