This is due to missing authentication, authorization, and nonce verification on a standalone PHP file that directly processes GET parameters and updates WordPress options. This makes it possible for unauthenticated attackers to modify the plugin's subscription plan settings, effectively downgrading the store from a paid plan to the Trial Plan, changing the store type, and manipulating subscription expiration dates, potentially disabling premium features such as Dropship and Hazardous Material handling.","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:L/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/ltl-freight-quotes-rl-edition/tags/3.3.11/en-hit-to-update-plan.php#L32","https://plugins.trac.wordpress.org/browser/ltl-freight-quotes-rl-edition/tags/3.3.11/en-hit-to-update-plan.php#L33","https://plugins.trac.wordpress.org/browser/ltl-freight-quotes-rl-edition/tags/3.3.11/en-hit-to-update-plan.php#L40","https://plugins.trac.wordpress.org/browser/ltl-freight-quotes-rl-edition/tags/3.3.11/en-hit-to-update-plan.php#L43","https://plugins.trac.wordpress.org/browser/ltl-freight-quotes-rl-edition/tags/3.3.11/en-hit-to-update-plan.php#L46"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-3646","score":0.00385,"percentile":0.32558,"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).
