This is due to missing capability checks on the AJAX handlers for install_addon, saveMappedFields, and StartImport, combined with the plugin nonce being exposed to any authenticated user who can load an admin page, allowing a Subscriber to install the Import WooCommerce add-on, persist attacker-controlled PHP expressions in the MappedFields parameter, and trigger evaluation via eval() in ImportHelpers::get_meta_values(). This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server.","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-94"],"references":["https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/8.0.1/InstallAddons.php#L66","https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/8.0.1/SaveMapping.php#L1562","https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/8.0.1/SaveMapping.php#L185","https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/8.0.1/wp-ultimate-csv-importer.php#L419","https://plugins.trac.wordpress.org/changeset/3591135/wp-ultimate-csv-importer"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-13353","score":0.0111,"percentile":0.6592,"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).
