CVE-2026-69208

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...

CVE-2026-85595

An authentication bypass vulnerability was discovered in Traefik's digestAuth middleware. When an incoming request contains a username that does not exist in the configured authentication store, the application fails to reject the request and instead evaluates the credential against an empty stri...

PT-2026-92378

The DigestAuth server middleware's stale-nonce cleanup uses an inverted comparison: it removes fresh nonces and stops at the first stale one. Because a new nonce is created for every unauthenticated challenge, an attacker can drive the nonce map to grow without bound until the JVM runs out of hea...

CVE-2026-85595

Traefik versions before v2.11.55 contain an authentication bypass in the digestAuth middleware . The root cause is that unknown usernames receive an empty secret instead of being rejected, allowing an attacker to compute a valid digest response using that empty secret and arbitrary credentials. T...
