{"id":"GHSA-7ww6-75fj-jcj7","summary":"Cross-site Scripting in Auth0 Lock","details":"### Overview\n\nIn versions before and including `11.32.2`, when the “additional signup fields” feature [is configured](https://github.com/auth0/lock#additional-sign-up-fields), a malicious actor can inject invalidated HTML code into these additional fields, which is then stored in the service `user_metdata` payload (using the `name` property).\n\nVerification emails, when applicable, are generated using this metadata. It is therefor possible for an actor to craft a malicious link by injecting HTML, which is then rendered as the recipient's name within the delivered email template.\n\n### Am I affected?\nYou are impacted by this vulnerability if you are using `auth0-lock` version `11.32.2` or lower and are using the “additional signup fields” feature in your application.\n\n### How to fix that?\nUpgrade to version `11.33.0`.\n\n### Will this update impact my users?\nAdditional signup fields that have been added to the signup tab on Lock will have HTML tags stripped from user input from version `11.33.0` onwards. The user will not receive any validation warning or feedback, but backend data will no longer include HTML.","aliases":["CVE-2022-29172"],"modified":"2023-11-08T04:09:08.744522Z","published":"2022-05-24T20:49:20Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-05-24T20:49:20Z","nvd_published_at":"2022-05-05T23:15:00Z","cwe_ids":["CWE-79"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/auth0/lock/security/advisories/GHSA-7ww6-75fj-jcj7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29172"},{"type":"WEB","url":"https://github.com/auth0/lock/commit/79ae557d331274b114848150f19832ae341771b1"},{"type":"PACKAGE","url":"https://github.com/auth0/lock"}],"affected":[{"package":{"name":"auth0-lock","ecosystem":"npm","purl":"pkg:npm/auth0-lock"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"11.33.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-7ww6-75fj-jcj7/GHSA-7ww6-75fj-jcj7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
