This makes it possible for unauthenticated attackers to read and exfiltrate another customer's stored billing and shipping address PII — including street address, city, state, postcode, phone number, company name, VAT number, and legal registration ID — by enumerating sequential AUTO_INCREMENT order and address ID pairs. The id-equality guard intended to restrict address reuse is bypassed because the attacker controls both halves of the compared pair, and the unauthenticated AJAX entry point imposes only a soft rate limit of 5 requests per 60 seconds rather than any authentication or ownership check.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L124","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L338","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L369","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/app/Hooks/Cart/WebCheckoutHandler.php#L132","https://plugins.trac.wordpress.org/changeset?reponame=&old=3734886%40fluent-cart&new=3734886%40fluent-cart"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-103525","score":0.00375,"percentile":0.31143,"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).
