To prevent this, I went to the extension area and tried to extend the register method, for this I wanted to do it using the sanitizeInput function that I know in the source codes of the strap. But the sanitizeInput function does not filter out private fields.\n\n```js\n const { auth } = ctx.state;\n const data = ctx.request.body;\n const userSchema = strapi.getModel(\"plugin::users-permissions.user\");\n\n sanitize.contentAPI.input(data, userSchema, { auth });\n```\n\nhere's the solution I've temporarily kept to myself, code snippet\n\n```js\n const body = ctx.request.body;\n\n const { attributes } = strapi.getModel(\"plugin::users-permissions.user\");\n\n const sanitizedData = _.omitBy(body, (data, key) => {\n  const attribute = attributes[key];\n\n  if (_.isNil(attribute)) {\n   return false;\n  }\n\n  //? If you want, you can throw an error for fields that we does not expect.\n\n  // if (_.isNil(attribute))\n  //  throw new ApplicationError(`Unexpected value ${key}`);\n\n  // if private value is true, we do not want to send it to the database.\n  return attribute.private;\n });\n\n return sanitizedData;\n```","aliases":[{"alias":"CVE-2023-39345"},{"alias":"GHSA-gc7p-j5xm-xxh2"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/67619?format=json","purl":"pkg:npm/%40strapi/plugin-users-permissions@4.13.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540strapi/plugin-users-permissions@4.13.1"},{"url":"http://public2.vulnerablecode.io/api/packages/67608?format=json","purl":"pkg:npm/%40strapi/strapi@4.13.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540strapi/strapi@4.13.1"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/61932?format=json","purl":"pkg:npm/strapi@4.0.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-jpqv-dukr-fyhu"},{"vulnerability":"VCID-qcu6-ntuc-byea"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/strapi@4.0.0"},{"url":"http://public2.vulnerablecode.io/api/packages/67618?format=json","purl":"pkg:npm/%40strapi/plugin-users-permissions@4.0.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-jpqv-dukr-fyhu"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540strapi/plugin-users-permissions@4.0.0"},{"url":"http://public2.vulnerablecode.io/api/packages/61970?format=json","purl":"pkg:npm/%40strapi/strapi@4.0.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-jpqv-dukr-fyhu"},{"vulnerability":"VCID-qcu6-ntuc-byea"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540strapi/strapi@4.0.0"}],"references":[{"reference_url":"https://strapi.io/blog/security-disclosure-of-vulnerabilities-sept-2023","reference_id":"","reference_type":"","scores":[],"url":"https://strapi.io/blog/security-disclosure-of-vulnerabilities-sept-2023"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-39345","reference_id":"CVE-2023-39345","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-39345"},{"reference_url":"https://github.com/advisories/GHSA-gc7p-j5xm-xxh2","reference_id":"GHSA-gc7p-j5xm-xxh2","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-gc7p-j5xm-xxh2"},{"reference_url":"https://github.com/strapi/strapi/security/advisories/GHSA-gc7p-j5xm-xxh2","reference_id":"GHSA-gc7p-j5xm-xxh2","reference_type":"","scores":[],"url":"https://github.com/strapi/strapi/security/advisories/GHSA-gc7p-j5xm-xxh2"}],"weaknesses":[{"cwe_id":1035,"name":"OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities","description":"Weaknesses in this category are related to the A9 category in the OWASP Top Ten 2017."},{"cwe_id":937,"name":"OWASP Top Ten 2013 Category A9 - Using Components with Known Vulnerabilities","description":"Weaknesses in this category are related to the A9 category in the OWASP Top Ten 2013."},{"cwe_id":287,"name":"Improper Authentication","description":"When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct."}],"exploits":[],"severity_range_score":null,"exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-jpqv-dukr-fyhu"}
