A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap. This occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maximum frame size handling and payload allocation occurs before the opcode is validated.

CVE-2026-85201——
——0In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded memory allocation that may abort the Ankaios agent process. This results in loss of orchestration services for workloads managed by the affected agent.5hCVE-2025-526573.5 BAJ—
——0HCL MyXalytics was affected by Potential DOS Vulnerability. It allows users to input data without any restriction on the number of characters which can impact system performance or availability.5hCVE-2022-510085.3 MED—
——0PocketMine-MP before 4.12.3 fails to limit unauthenticated sessions, allowing attackers to exhaust player slots by creating sessions without sending LoginPacket. Attackers can flood the server with unauthenticated connections that occupy max-player slots, preventing legitimate players from joining.1dCVE-2026-857036.5 MED25.9%
——8A flaw has been found in ramon-victor freegpt-webui up to 098db3dfeb41555c2ca9269df0f13e10ec1c35dc. Affected by this issue is the function getJailbreak of the file server/backend.py of the component Jailbreak Mode. Executing a manipulation can lead to allocation of resources. The attack can be executed remotely. The exploit has been published and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. This vulnerability only affects products that are no longer supported by the maintainer.3dCVE-2026-848905.9 MED16.3%
——5undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding header. While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no configuration option to limit it. A malicious or faulty upstream can therefore return a small compressed payload, a compression bomb, that expands to hundreds of megabytes or more in client memory, an asymmetric resource consumption that can exhaust memory and crash the process. This affects undici versions from 7.15.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.3dCVE-2026-856647.5 ALT29.7%
——9Chroma 1.5.9 fails to validate maximum bounds on HNSW index parameters max_neighbors, ef_construction, and ef_search in collection-create requests. Unauthenticated attackers can supply arbitrarily large parameter values to exhaust server memory and cause denial of service during index compaction.3d
