CVE-2026-69193 error311 CVE debrief
CVE-2026-69193 is a vulnerability in FileRise, a self-hosted web-based file manager, that allows for rate limiting bypass via username rotation, enabling unlimited password spraying. This issue is fixed in version 3.21.0. The vulnerability arises from FileRise tracking failed logins only by the combination of source IP address and username, allowing a remote unauthenticated attacker to rotate usernames and obtain a fresh per-account attempt budget for each name. Defenders should assess exposure and prioritize upgrading to version 3.21.0 or later to prevent exploitation.

Who should care
Defenders responsible for FileRise installations should assess exposure and prioritize upgrading to version 3.21.0 or later. They should also review and update affected systems, monitor for suspicious activity, and verify inventory to prevent exploitation. Defenders should also consider compensating controls for exposed systems while remediation is scheduled and verified.
Why it matters
CVE-2026-69193 allows for rate limiting bypass via username rotation in FileRise, enabling unlimited password spraying. Defenders should prioritize upgrading to version 3.21.0 or later.
- Password spraying attacks may be performed against FileRise installations
- Defenders should verify inventory and upgrade to version 3.21.0 or later
Technical summary
FileRise tracks failed logins only by the combination of source IP address and username. A remote unauthenticated attacker can rotate usernames to obtain a fresh per-account attempt budget for each name, enabling password spraying from one source beyond the intended limit. Per-user limits still apply and can also produce distinguishable throttling behavior for targeted accounts. The affected surface is AuthModel::getFailedLoginKey(). This issue is fixed in version 3.21.0. Defenders should prioritize upgrading to version 3.21.0 or later to prevent exploitation.
Defensive priority

- Monitor for suspicious activity
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
