{"cve":"CVE-2023-41881","nvd":{"published":"2023-10-11T20:15:10.617","modified":"2026-06-17T06:22:59.860","status":"Modified","description":"vantage6 is privacy preserving federated learning infrastructure. When a collaboration is deleted, the linked resources (such as tasks from that collaboration) should be deleted. This is partly to manage data properly, but also to prevent a potential (but unlikely) side-effect that affects versions prior to 4.0.0, where if a collaboration with id=10 is deleted, and subsequently a new collaboration is created with id=10, the authenticated users in that collaboration could potentially see results of the deleted collaboration in some cases. Version 4.0.0 contains a patch for this issue. There are no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200","CWE-708"],"references":["https://github.com/vantage6/vantage6/blob/0682c4288f43fee5bcc72dc448cdd99bd7e57f76/docs/release_notes.rst#400","https://github.com/vantage6/vantage6/pull/748","https://github.com/vantage6/vantage6/security/advisories/GHSA-rf54-7qrr-96j6","https://github.com/vantage6/vantage6/blob/0682c4288f43fee5bcc72dc448cdd99bd7e57f76/docs/release_notes.rst#400","https://github.com/vantage6/vantage6/pull/748"],"products":["vantage6:vantage6"],"source":"nvd","synced_at":"2026-10-19T21:39:34.467980132+00:00"},"epss":{"cve":"CVE-2023-41881","score":0.00354,"percentile":0.29099,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rf54-7qrr-96j6","url":"https://osv.dev/vulnerability/GHSA-rf54-7qrr-96j6","summary":"vantage6 does not properly delete linked resources when deleting a collaboration","modified":"2026-09-10T03:49:24.763224817Z","packages":[{"ecosystem":"PyPI","name":"vantage6","purl":"pkg:pypi/vantage6","ranges":["<4.0.0"],"fixed":["4.0.0"]}]},{"id":"PYSEC-2023-200","url":"https://osv.dev/vulnerability/PYSEC-2023-200","summary":"","modified":"2023-11-08T04:13:26.641446Z","packages":[{"ecosystem":"PyPI","name":"vantage6","purl":"pkg:pypi/vantage6","ranges":["<4.0.0"],"fixed":["4.0.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
