{"id":"CVE-2024-45399","state":"PUBLISHED","title":"Indico has a Cross-Site-Scripting during account creation","description":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In Indico prior to version 3.3.4, corresponding to Flask-Multipass prior to version 0.5.5, there is a Cross-Site-Scripting vulnerability during account creation when redirecting to the `next` URL. Exploitation requires initiating the account creation process with a maliciously crafted link, and then finalizing the signup process. Because of this, it can only target newly created (and thus unprivileged) Indico users. Indico 3.3.4 upgrades the dependency on Flask-Multipass to version 0.5.5, which fixes the issue. Those who build the Indico package themselves and cannot upgrade can update the `flask-multipass` dependency to `>=0.5.5` which fixes the vulnerability. Otherwise one could configure one's web server to disallow requests containing a query string with a `next` parameter that starts with `javascript:`.","publishedAt":"2024-09-04T20:12:20.457Z","updatedAt":"2024-09-04T20:17:38.298Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["indico indico"],"affected":[{"vendor":"indico","product":"indico","versions":[{"version":"< 3.3.4","status":"affected"}]}],"references":["https://github.com/indico/indico/security/advisories/GHSA-rrqf-w74j-24ff","https://github.com/indico/flask-multipass/commit/0bdcf656d469e5f675cb56fd644d82fea3a97c2a","https://github.com/indico/indico/commit/7dcb573837b9fd09d95f74d1baeae225b164cc8f","https://github.com/indico/indico/releases/tag/v3.3.4"],"weaknesses":["CWE-79","CWE-1395"],"ingestedAt":"2026-10-29T20:07:47.831Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/45xxx/CVE-2024-45399.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-45399","state":"PUBLISHED","datePublished":"2024-09-04T20:12:20.457Z","dateUpdated":"2024-09-04T20:17:38.298Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-08-28T20:21:32.803Z"},"containers":{"cna":{"title":"Indico has a Cross-Site-Scripting during account creation","descriptions":[{"lang":"en","value":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask.
