NewCVE-2026-69208 (opens in a new tab)How to fix?
Upgrade org.http4s:http4s-server_2.12 to version 0.23.35 or higher.
Overview
org.http4s:http4s-server_2.12 is a base library for building http4s servers.
Affected versions of this package are vulnerable to Missing Release of Memory after Effective Lifetime via the DigestAuth process. An attacker can cause the application to exhaust system memory by repeatedly triggering unauthenticated challenges, leading to unbounded growth of the nonce map and eventual denial of service.
Note: This is only exploitable if the application uses DigestAuth on at least one route.
Workaround
This vulnerability can be mitigated by fronting the protected routes with a rate limiter to slow the leak or by periodically restarting the service.
