The regex that validates user emails took exponentially longer to process long input strings beginning with `@` characters.\n\n### Impact\nThe issue affects the `email` function. If you use this function to process arbitrary user input with no character limit the application may be susceptible to Denial of Service.\n\n### Patches\nThe issue is patched in version 1.0.1 by improving the regular expression used and also enforcing a 254 character limit.\n\n### Workarounds\nRestrict the character length to a reasonable degree before passing a value to `.emal()`; Also, consider doing a more rigorous sanitizing/validation beforehand.","references":[{"reference_url":"https://github.com/npm/npm-user-validate/security/advisories/GHSA-xgh6-85xh-479p","reference_id":"","reference_type":"","scores":[{"value":"LOW","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/npm/npm-user-validate/security/advisories/GHSA-xgh6-85xh-479p"},{"reference_url":"https://github.com/advisories/GHSA-xgh6-85xh-479p","reference_id":"GHSA-xgh6-85xh-479p","reference_type":"","scores":[{"value":"LOW","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-xgh6-85xh-479p"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/72641?format=json","purl":"pkg:npm/npm-user-validate@1.0.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/npm-user-validate@1.0.1"}],"aliases":["GHSA-xgh6-85xh-479p"],"risk_score":1.4,"exploitability":"0.5","weighted_severity":"2.7","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-khpz-njyn-5qd1"}],"fixing_vulnerabilities":[],"risk_score":"1.4","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/npm-user-validate@1.0.0"}
