GHSA-MC5J-F6WX-H9QH Filament: Multi-factor authentication (app) recovery codes can still be used multiple times via concurrent submission

A flaw in the handling of recovery codes for app-based multi-factor authentication allows the same recovery code to be reused via concurrent submission. This issue does not affect email-based MFA. It also only applies when recovery codes are enabled. If an attacker gains access to both the user's...

CVE-2026-40211 Denial of service via crafted DoH3 queries

An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3 streams to trigger an out-of-memo...
