Vulnerability in org.http4s:http4s-ember-server_2.12 (CVE-2026-69208)
Summary
Vulnerability in org.http4s:http4s-ember-server_2.12 (CVE-2026-69208). Risk of unauthorized operations or information disclosure. Exploitable via DigestAuth. Mitigation: upgrade to 0.23.35 or later.
Original description
The description as published by the source.
Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, the DigestAuth server middleware removes fresh nonces and stops eviction at the first stale nonce because its stale-nonce comparison is inverted. On an application that protects at least one route with DigestAuth, an unauthenticated attacker can repeatedly trigger authentication challenges, causing the persistent nonce map to grow until the JVM exhausts heap memory. This issue is fixed in versions 0.23.35 and 1.0.0-M47.
