{"id":"CVE-2024-24769","kind":"vulnerability","aliases":["CVE-2024-24769","GHSA-5549-c5q7-fj65"],"related":[],"title":"Vantage6: No limit on emails sent for password/MFA reset","description":"vantage6 is an open-source infrastructure for privacy preserving analysis. Prior to version 5.0.0, users can reset their MFA token via API routes that send them an email. Currently the number of emails that is sent is not limited. This gives attackers the option to flood someones mailbox with a lot of emails, and would have adverse effects on the SMTP server which may be seen as spam sender. Note resetting the MFA token requires a correct password, so the potential impact for this is very low. Version 5.0.0 fixes the issue. No known workarounds are available.","summary":"Vantage6 does not limit how many password or MFA reset emails the API sends. An attacker who knows a valid password can flood a user's mailbox and get the SMTP server flagged as a spam sender.","severity":"low","cvss":2.1,"epss":0.00278,"exploited":false,"exploited_at":null,"products":[{"name":"vantage6","fixed":["5.0.0"],"affected":"< 5.0.0","ecosystem":"pypi"}],"ecosystems":["pypi"],"tags":["cwe-400","package","python","self-hosted","vantage6"],"not_affected_if":["no-mfa-reset-route-exposed","version-5-or-later"],"how_to_check":"- Check the installed `vantage6` version with `pip show vantage6`\n- Look for the affected version range below 5.0.0 in your Python environments","fix":"- `vantage6` `5.0.0` (fixed version per the advisory range; the advisory itself states no patches were available at the time)","status":"open","published_at":"2026-06-05T15:21:59+00:00","first_seen_at":"2026-11-03T16:20:23+00:00","triaged_at":"2026-11-03T16:21:26+00:00","updated_at":"2026-11-03T16:21:46+00:00","category":"package","confidence":0.7,"triage":{"at":"2026-11-03T16:21:26Z","model":"claude-haiku-5-5","output":{"fix":"- `vantage6` `5.0.0` (fixed version per the advisory range; the advisory itself states no patches were available at the time)","reach":"internet","title":"Vantage6: password and MFA reset emails have no sending limit","impact":"low","summary":"Vantage6 does not limit how many password or MFA reset emails the API sends.
