The value of this variable is a URL which typically includes a private IP address, private domain name, and/or port.\n\nThis vulnerability allows an unauthenticated attacker to make a HTTP GET request from the Privacy Center that discloses the value of this server-side URL.\n\n### Impact\n\nDisclosure of server-side configuration giving an attacker information on server-side ports, private IP addresses, and/or private domain names.\n\n### Patches\nThe vulnerability has been patched in Fides version `2.39.2`. Users are advised to upgrade to this version or later to secure their systems against this threat.\n\n### Workarounds\nThere are no workarounds.\n\n### Proof of Concept\n\n1. Set the value of the environment variable `FIDES_PRIVACY_CENTER__SERVER_SIDE_FIDES_API_URL` of your Fides Privacy Center container before start-up to a private value such as `https://some.private.domain.name/api/v1` and start the Privacy Center application.\n\n2. Once the application is up, perform a HTTP GET request of the Privacy Center's main page e.g. `https://privacy.example.com` . The value of `SERVER_SIDE_FIDES_API_URL` is returned in the response's body.\n\n\n```\n~ ❯ curl -s https://privacy.example.com/ | \\\ngrep '__NEXT_DATA__' | \\\nsed 's/.*<script id=\"__NEXT_DATA__\" type=\"application\\/json\">//;s/<\\/script>.*//' | \\\njq '.props.serverEnvironment.settings.SERVER_SIDE_FIDES_API_URL'\n\"https://some.private.domain.name/api/v1\"\n```","affected":[{"package":{"name":"ethyca-fides","ecosystem":"PyPI","purl":"pkg:pypi/ethyca-fides"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.19.0"},{"fixed":"2.39.2"}]}],"versions":["2.19.0","2.19.1","2.20.0","2.20.1","2.20.2","2.21.0","2.22.0","2.22.1","2.23.0","2.23.1","2.23.2","2.23.3","2.24.0","2.24.1","2.25.0","2.26.0","2.26.3","2.27.0","2.28.0","2.29.0","2.30.0","2.30.1","2.31.0","2.32.0","2.33.0","2.33.1","2.34.0","2.35.0","2.35.1","2.36.0","2.37.0","2.38.0","2.38.1","2.39.0","2.39.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/07/GHSA-53q7-4874-24qg/GHSA-53q7-4874-24qg.json"}}],"references":[{"type":"WEB","url":"https://github.com/ethyca/fides/security/advisories/GHSA-53q7-4874-24qg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31223"},{"type":"WEB","url":"https://github.com/ethyca/fides/commit/0555080541f18a5aacff452c590ac9a1b56d7097"},{"type":"WEB","url":"https://github.com/ethyca/fides/commit/cd510216b281de5443ec1c126add95cc5be0970a"},{"type":"PACKAGE","url":"https://github.com/ethyca/fides"}],"database_specific":{"cwe_ids":["CWE-497"],"github_reviewed":true,"github_reviewed_at":"2024-07-05T20:40:06Z","nvd_published_at":"2024-07-03T18:15:05Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
