  1. CVE-2026-87742 7.5 Élevée

    Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2 · Red Hat Exploit Intelligence · Red Hat Enterprise Linux AI (RHEL AI) 3

    A flaw was found in quarkus-websockets-next. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by streaming messages over a single connection faster than the application can process them. Due to unbounded message buffering and a lack of read backpressure, this rapidly exhausts heap space, leading to a java.lang.OutOfMemoryError that crashes the Java Virtual Machine (JVM).

  2. CVE-2026-81829 5.3 Moyenne

    Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2 · Red Hat Exploit Intelligence · Red Hat build of Apicurio Registry 3

    A flaw was found in SmallRye JWT's AwsAlbKeyResolver, which is used by applications to verify JSON Web Tokens signed by AWS Application Load Balancers. When the AWS_ALB key provider is configured, the resolver constructs the key-fetch URL by directly concatenating the attacker-controlled kid header value from an inbound JWT without sanitizing path traversal characters or query-string separators. This allows an unauthenticated remote attacker to force the application server to issue GET requests to arbitrary paths on the same origin as the configured key endpoint. As a result, non-public endpoints or internal data reachable on that origin may be read by the attacker before JWT signature verification takes place.
