| CVE-2026-41484 | 1 Opentelemetry | 1 Opentelemetry-dotnet-contrib | 2026-05-07 | 5.3 Medium |
| OpenTelemetry.Exporter.OneCollector is a .NET exporter that sends telemetry to a OneCollector back-end over HTTP. In versions 1.15.0 and earlier, when a request to the configured back-end or collector results in an unsuccessful HTTP 4xx or 5xx response, the HttpJsonPostTransport class reads the entire response body into memory with no upper bound on the number of bytes consumed in order to include the error response in operator logs. An attacker who controls the configured endpoint, or who can intercept traffic to it via a man-in-the-middle attack, can return an arbitrarily large response body. This causes unbounded heap allocation in the consuming process, leading to high transient memory pressure, garbage-collection stalls, or an OutOfMemoryException that terminates the process. As a workaround, use network-level controls such as firewall rules, mTLS, or a service mesh to prevent man-in-the-middle attacks on the configured back-end or collector endpoint. This issue is fixed in version 1.15.1, which limits the number of bytes read from the response body in an error condition to 4 MiB. | ||||
| CVE-2026-41483 | 1 Opentelemetry | 1 Opentelemetry-dotnet-contrib | 2026-05-07 | 5.9 Medium |
| OpenTelemetry.Resources.Azure is the .NET resource detector for Azure environments. In versions 1.15.0-beta.1 and earlier, the AzureVmMetaDataRequestor class makes HTTP requests to the Azure VM instance metadata service and reads the response body into memory without any size limit. An attacker who controls the configured endpoint, or who can intercept traffic to it via a man-in-the-middle attack, can return an arbitrarily large response body. This causes unbounded heap allocation in the consuming process, leading to high transient memory pressure, garbage-collection stalls, or an OutOfMemoryException that terminates the process. As a workaround, disable the Azure VM resource detector or use network-level controls such as firewall rules, mTLS, or a service mesh to prevent man-in-the-middle attacks on the Azure VM instance metadata endpoint. This issue is fixed in version 1.15.1-beta.1, which streams responses rather than buffering them entirely in memory and ignores responses larger than 4 MiB. | ||||
| CVE-2026-41310 | 1 Opentelemetry | 1 Opentelemetry-dotnet | 2026-05-07 | 5.3 Medium |
| OpenTelemetry.Exporter.Zipkin is the .NET Zipkin exporter for OpenTelemetry. In versions 1.15.2 and earlier, the Zipkin exporter remote endpoint cache accepts unbounded key growth derived from span attributes. In high-cardinality scenarios, a process using Zipkin export for client or producer spans could experience avoidable memory growth under sustained unique remote endpoint values, increasing process memory usage over time and degrading availability. This issue is fixed in version 1.15.3, which introduces a bounded, thread-safe LRU cache for remote endpoints with a fixed maximum size. | ||||
| CVE-2025-66369 | 1 Samsung Mobile | 1 Exynos | 2026-05-07 | 7.5 High |
| An issue was discovered in MM in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 980, 990, 850, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, W920, W930, W1000, Modem 5123, and Modem 5300. Incorrect handling of 5G NR NAS registration accept messages leads to a Denial of Service. | ||||
| CVE-2026-31677 | 1 Linux | 1 Linux Kernel | 2026-05-07 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - limit RX SG extraction by receive buffer budget Make af_alg_get_rsgl() limit each RX scatterlist extraction to the remaining receive buffer budget. af_alg_get_rsgl() currently uses af_alg_readable() only as a gate before extracting data into the RX scatterlist. Limit each extraction to the remaining af_alg_rcvbuf(sk) budget so that receive-side accounting matches the amount of data attached to the request. If skcipher cannot obtain enough RX space for at least one chunk while more data remains to be processed, reject the recvmsg call instead of rounding the request length down to zero. | ||||
| CVE-2026-23870 | 2026-05-06 | 7.5 High | ||
| A denial of service vulnerability could be triggered by sending specially crafted HTTP requests to server function endpoints, this could lead to server crashes, out-of-memory exceptions or excessive CPU usage; affecting the following packages: react-server-dom-webpack, react-server-dom-parcel, react-server-dom-turbopack (versions 19.0.0 through 19.0.5, 19.1.0 through 19.1.6, and 19.2.0 through 19.2.5). | ||||
| CVE-2026-42236 | 1 N8n | 1 N8n | 2026-05-06 | 7.5 High |
| n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, the MCP OAuth client registration endpoint accepted unauthenticated requests and stored client data without adequate resource controls. An unauthenticated remote attacker could exhaust server memory resources by sending large registration payloads, rendering the n8n instance unavailable. The MCP enable/disable toggle gates MCP access but did not restrict client registrations, meaning the endpoint is reachable regardless of whether MCP access is enabled on the instance. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1. | ||||
| CVE-2025-2559 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-05-06 | 4.9 Medium |
| A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could result in a denial of service condition, preventing legitimate users from accessing the system. | ||||
| CVE-2026-32689 | 1 Phoenixframework | 1 Phoenix | 2026-05-06 | N/A |
| Allocation of Resources Without Limits or Throttling vulnerability in phoenixframework phoenix allows a denial of service via the long-poll transport's NDJSON body handling. In 'Elixir.Phoenix.Transports.LongPoll':publish/4, when a POST request is received with Content-Type: application/x-ndjson, the request body is split on newline characters using String.split/2 with no limit on the number of resulting segments. An attacker can send a body consisting entirely of newline bytes, causing a 1:1 amplification into a list of empty binaries — a 1 MB body produces approximately one million list elements, an 8 MB body approximately 8.4 million. Each element is then walked by Enum.map, materializing another list of the same size. This exhausts BEAM memory and schedulers, crashing the node and terminating all active sessions. A session token required to reach the vulnerable endpoint is freely obtainable by any client via an unauthenticated GET request to the same URL with a matching Origin header, making this attack effectively unauthenticated. This issue affects phoenix: from 1.7.0 before 1.7.22 and 1.8.6. | ||||
| CVE-2026-32934 | 1 Coredns.io | 1 Coredns | 2026-05-06 | N/A |
| CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the DNS-over-QUIC (DoQ) server can be driven into unbounded goroutine and memory growth by a remote client that opens many QUIC streams and sends only 1 byte per stream. When the worker pool is full, CoreDNS still spawns a goroutine per accepted stream to wait for a worker token. Additionally, active workers block indefinitely in io.ReadFull() with no per-stream read deadline, allowing an attacker to pin all workers by sending a single byte so the read blocks waiting for the second byte of the DoQ length prefix. This enables an unauthenticated remote attacker to cause memory exhaustion and OOM-kill. This issue has been fixed in version 1.14.3. No known workarounds exist. | ||||
| CVE-2025-9784 | 1 Redhat | 16 Apache Camel Hawtio, Apache Camel Spring Boot, Build Of Apache Camel For Spring Boot and 13 more | 2026-05-06 | 7.5 High |
| A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS). | ||||
| CVE-2026-43096 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mshv: Fix infinite fault loop on permission-denied GPA intercepts Prevent infinite fault loops when guests access memory regions without proper permissions. Currently, mshv_handle_gpa_intercept() attempts to remap pages for all faults on movable memory regions, regardless of whether the access type is permitted. When a guest writes to a read-only region, the remap succeeds but the region remains read-only, causing immediate re-fault and spinning the vCPU indefinitely. Validate intercept access type against region permissions before attempting remaps. Reject writes to non-writable regions and executes to non-executable regions early, returning false to let the VMM handle the intercept appropriately. This also closes a potential DoS vector where malicious guests could intentionally trigger these fault loops to consume host resources. | ||||
| CVE-2026-7768 | 1 Fastify | 1 Fastify-accepts-serializer | 2026-05-06 | 7.5 High |
| @fastify/accepts-serializer cached serializer-selection results keyed by the request Accept header without a size limit or eviction policy. A remote unauthenticated client could send many distinct but matching Accept header variants to make the cache grow unbounded, eventually exhausting the Node.js heap and crashing the process. Versions <= 6.0.3 are affected. Update to 6.0.4 or later, which bounds the cache via an LRU with a default size of 100 entries, configurable through the new cacheSize plugin option. | ||||
| CVE-2026-7776 | 1 Hashicorp | 2 Boundary, Boundary Enterprise | 2026-05-06 | 7.5 High |
| Boundary Community Edition and Boundary Enterprise (“Boundary”) workers are vulnerable to a denial-of-service condition during node enrollment TLS handshakes. An attacker with network access to the worker authentication listener may open a connection and delay or withhold the client certificate during the TLS handshake, causing worker connection handling to block. This may prevent legitimate worker connections from being accepted or routed. This vulnerability, CVE-2026-7776, is fixed in Boundary 0.21.3, 0.20.3, 0.19.5. | ||||
| CVE-2026-29168 | 1 Apache | 1 Http Server | 2026-05-05 | 7.3 High |
| Allocation of Resources Without Limits or Throttling vulnerability in Apache HTTP Server's mod_md via OCSP response data. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue. | ||||
| CVE-2026-42437 | 1 Openclaw | 1 Openclaw | 2026-05-05 | 7.5 High |
| OpenClaw versions 2026.4.9 before 2026.4.10 contain a denial of service vulnerability in the voice-call realtime WebSocket path that accepts oversized frames without proper validation. Remote attackers can send oversized WebSocket frames to cause service unavailability for deployments exposing the webhook path. | ||||
| CVE-2025-70069 | 1 Assimp | 1 Assimp | 2026-05-05 | 7.5 High |
| An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXConverter.cpp and ConvertMeshMultiMaterial() method | ||||
| CVE-2025-70072 | 1 Assimp | 1 Assimp | 2026-05-04 | 6.5 Medium |
| An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXConverter.cpp, FBXConverter::ConvertMeshMultiMaterial() components | ||||
| CVE-2025-70071 | 1 Assimp | 1 Assimp | 2026-05-04 | 5.9 Medium |
| An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXParser.cpp, ParseVectorDataArray() | ||||
| CVE-2025-51846 | 2 Cryptpad, Xwiki | 2 Cryptpad, Cryptpad | 2026-05-04 | 7.5 High |
| CryptPad 2025.3.1 allows unbounded WebSocket frame flood. A remote, unauthenticated attacker can significantly degrade or deny service for all users of a CryptPad instance. Fixed in 2026.2.2. | ||||
