EUVD-2026-41500

By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages...

CVE-2026-11586

The CVE-2026-11586 issue affects curl’s WebSocket handling: curl auto-responds to PING frames and has no upper bound on memory allocation for unacknowledged frames, enabling memory exhaustion via rapid PING floods. Affected are curl versions prior to 8.21.0 (e.g., 8.16.0). Remediation: upgrade to...

CVE-2026-48044

A flaw was found in Envoy, an open source edge and service proxy. A remote attacker can exploit this vulnerability by sending a specially crafted, highly compressed zstd payload to an Envoy proxy with zstd decompression enabled. This can lead to massive memory allocation, causing severe memory...

CVE-2026-11946

A flaw was found in open62541. An unauthenticated remote attacker can exploit a vulnerability in the GetEndpoints Discovery Service by sending a malformed request with an excessively long, unvalidated endpointUrl field. This can lead to the server buffering large amounts of data indefinitely,...

CVE-2026-47262

A flaw was found in containerd, an open-source container runtime. A remote attacker could exploit this vulnerability by providing a maliciously crafted image. When a container is created from this image, it leads to uncontrolled resource consumption and memory exhaustion, causing the containerd...

CVE-2026-11946

An unauthenticated remote attacker can exhaust server memory via the GetEndpoints Discovery Service in open62541. The endpointUrl field of GetEndpointsRequest is not validated for length. An attacker can declare an arbitrarily large string up to 4.09 GB via the UInt32 length field delivered acros...

CVE-2026-11946

CVE-2026-11946 affects open62541 (1.4.0–1.4.16, 1.5.0–1.5.4, master). An unauthenticated remote attacker can exhaust server memory through GetEndpoints by sending an oversized endpointUrl in GetEndpointsRequest; length is not validated, allowing ~4.09 GB strings split across chunks, buffered in R...

CVE-2026-11946 GetEndpoints Memory Exhaustion in open62541

An unauthenticated remote attacker can exhaust server memory via the GetEndpoints Discovery Service in open62541. The endpointUrl field of GetEndpointsRequest is not validated for length. An attacker can declare an arbitrarily large string up to 4.09 GB via the UInt32 length field delivered acros...

CVE-2026-33592

An unauthenticated remote attacker can exhaust server memory via the FindServers Discovery Service in open62541. The serverUris field of FindServersRequest is not validated for length or array size. An attacker can declare an arbitrarily large string up to 3.9 GB delivered across intermediate...

CVE-2026-33592
