OneCollector exporter reads unbounded HTTP response bodies

Summary When exporting telemetry to a back-end/collector over HTTP using the OpenTelemetry.Exporter.OneCollector exporter, if the request results in a unsuccessful request i.e. HTTP 4xx or 5xx, the response is read into memory with no upper-bound on the number of bytes consumed. This could cause...

Allocation of Resources Without Limits or Throttling

Overview OpenTelemetry.Exporter.Zipkin is a Zipkin Exporter for OpenTelemetry .NET. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to unbounded growth of the remote endpoint cache derived from span attributes. An attacker can cause...

OpenTelemetry's Zipkin remote endpoint cache could grow without bounds and increase memory pressure

Summary The Zipkin exporter remote endpoint cache accepted unbounded key growth derived from span attributes. In high-cardinality scenarios, this could increase process memory usage over time and degrade availability. Details - Introduce a bounded, thread-safe LRU cache for remote endpoints. -...

freerdp: FreeRDP has a heap-buffer-overflow in urb_select_interface

A heap buffer overflow has been discovered in FreeRDP. The URBDRC client uses server-supplied interface numbers as array indices without bounds checks, causing an out-of-bounds read in libusbudevselectinterface...

PT-2026-37094

Name of the Vulnerable Software and Affected Versions CoreDNS versions prior to 1.14.3 Description The DNS-over-QUIC DoQ server can be forced into unbounded goroutine and memory growth by a remote unauthenticated client. This occurs when a client opens numerous QUIC streams and sends only one byt...

nix: coroutine stack-to-heap overflow via unbounded recursion in NAR directory parser

A flaw was found in Nix. Unbounded recursion in the NAR Nix Archive parser could lead to a stack-to-heap overflow when the parser is run on a coroutine stack. The stack is allocated without a guard page, which means that a stack overflow could overwrite memory on the heap and could allow arbitrar...

CVE-2026-33524 Zserio: Integer Overflow in BitStreamReader and Unbounded Memory Allocation in Deserialization

Zserio is a framework for serializing structured data with a compact and efficient way with low overhead. Prior to 2.18.1, a crafted payload as small as 4-5 bytes can force memory allocations of up to 16 GB, crashing any process with an OOM error Denial of Service. This vulnerability is fixed in...

CVE-2026-42039

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. This vulnerability is fixed in 1.15.1 and...

CVE-2026-42036

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when responseType: 'stream' is used, Axios returns the response stream without enforcing maxContentLength. This bypasses configured response-size limits and allows unbounded downstream consumption. This...
