Replay Attack
Overview org.http4s:http4s-server2.12 is a base library for building http4s servers. Affected versions of this package are vulnerable to Replay Attack through improper handling of the DigestAuth process. An attacker can execute authenticated requests as another user by replaying a previously...

CVE-2026-69206
Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, DigestAuth replay protection records lastNc plus one instead of the highest nonce-count value it has accepted. When a legitimate client sends noncontiguous nc values because of parallel or retried requests, the stored...
Http4s: DigestAuth nonce map grows unbounded
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...

Missing Release of Memory after Effective Lifetime
Overview 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...

GHSA-9XWW-74XV-GJFP Http4s: DigestAuth allows replay of captured requests
The DigestAuth replay defence stores lastNc + 1 rather than the nonce-count nc value it just accepted. When a legitimate client sends non-contiguous nc values parallel or retried requests, as browsers do, the server's counter lags behind the highest nc seen, and a captured Authorization header ca...

CVE-2026-69206
Http4s (a Scala HTTP service framework) has a DigestAuth replay vulnerability prior to versions 0.23.35 and 1.0.0-M47 . The replay protection records lastNc + 1 instead of the highest accepted nonce-count value. When a legitimate client sends noncontiguous nc values (due to parallel or retried re...
