{"id":"CVE-2023-37901","aliases":["GHSA-fmqq-25x9-c6hm","PYSEC-2023-129"],"url":"https://o3.security/vulnerability/CVE-2023-37901","summary":"Cross-Site-Scripting via confirmation prompts","details":"### Impact\nThere is a Cross-Site-Scripting vulnerability in confirmation prompts commonly used when deleting content from Indico.\nExploitation requires someone with at least submission privileges (such as a speaker) and then someone else to attempt to delete this content.\n\nConsidering that event organizers may want to delete suspicious-looking content when spotting it, there is a non-negligible risk of such an attack to succeed. The risk of this could be further increased when combined with some some social engineering pointing the victim towards this content.\n\n### Patches\nYou need to update to [Indico 3.2.6](https://github.com/indico/indico/releases/tag/v3.2.6) as soon as possible.\nSee [the docs](https://docs.getindico.io/en/stable/installation/upgrade/) for instructions on how to update.\n\n### Workarounds\nOnly let trustworthy users manage categories, create events or upload materials (\"submission\" privileges on a contribution/event). This should already be the case in a properly-configured setup when it comes to category/event management.\n\nNote that a conference doing a Call for Abstracts actively invites external speakers (who the organizers may not know and thus cannot fully trust) to submit content, hence the need to update to a a fixed version ASAP in particular when using such workflows.\n\nFor more information\n\nIf you have any questions or comments about this advisory:\n\n* Open a thread in [our forum](https://talk.getindico.io/)\n* Email us privately at [indico-team@cern.ch](mailto:indico-team@cern.ch)","published":"2023-07-21T18:14:25.481Z","modified":"2026-08-12T03:51:35.811613751Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"indico","fixedVersion":"3.2.6"}],"fix":{"url":"https://github.com/indico/indico/commit/2ee636d318653fb1ab193803dafbfe3e371d4130","label":"indico/indico@2ee636d"},"references":[{"type":"WEB","url":"https://docs.getindico.io/en/stable/installation/upgrade/"},{"type":"WEB","url":"https://github.com/indico/indico/releases/tag/v3.2.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/37xxx/CVE-2023-37901.json"},{"type":"ADVISORY","url":"https://github.com/indico/indico/security/advisories/GHSA-fmqq-25x9-c6hm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-37901"},{"type":"FIX","url":"https://github.com/indico/indico/commit/2ee636d318653fb1ab193803dafbfe3e371d4130"},{"type":"WEB","url":"https://docs.getindico.io/en/stable/installation/upgrade"},{"type":"PACKAGE","url":"https://github.com/indico/indico"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/indico/PYSEC-2023-129.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.811613751Z"}}
