This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the 'Generic Errors' setting is unchecked, causing getErrorMessage() to return the raw Stripe error string unchanged rather than substituting a mapped safe message.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/woo-stripe-payment/tags/4.0.14/assets/build/controllers.js#L1","https://plugins.trac.wordpress.org/browser/woo-stripe-payment/tags/4.0.14/assets/build/dom-events.js#L1","https://plugins.trac.wordpress.org/browser/woo-stripe-payment/tags/4.0.14/assets/build/gateways.js#L1","https://plugins.trac.wordpress.org/browser/woo-stripe-payment/tags/4.0.14/assets/build/utils.js#L1","https://plugins.trac.wordpress.org/changeset/3726506/woo-stripe-payment/trunk/assets/build/controllers.js"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-89100","score":0.00215,"percentile":0.11807,"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).
