The Parse function processes arbitrarily large or invalid baggage headers a...

CVE-2026-44902 opentelemetry-js: Prometheus exporter process crash via malformed HTTP request

opentelemetry-js is the OpenTelemetry JavaScript Client. Prior to 0.217.0, a single malformed HTTP request crashes any Node.js process running the OpenTelemetry JS Prometheus exporter. The metrics endpoint default 0.0.0.0:9464 has no error handling around URL parsing, so a request with an invalid...

GO-2026-4985 Oversized OTLP HTTP response bodies can cause memory exhaustion in go.opentelemetry.io/otel/exporters/otlp

The OTLP HTTP exporters traces, metrics, and logs do not limit the size of the HTTP response body read from the collector. A malicious or misconfigured collector can send a large response body, leading to excessive memory consumption and potential process termination OOM...

Important: Red Hat Security Advisory: opentelemetry-collector security update

An update for opentelemetry-collector is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating,...

Amazon Linux 2023 : docker (ALAS2023-2026-1659)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1659 advisory. Moby is an open source container framework. Prior to version 29.3.1, a security vulnerability has been detected that allows plugins privilege validation to be bypassed during docker plugin...

RHEL 10 : opentelemetry-collector (RHSA-2026:19135)

The remote Redhat Enterprise Linux 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2026:19135 advisory. Collector with the supported components for a Red Hat build of OpenTelemetry Security Fixes: net/url: Incorrect parsing of IPv6 host...

Spring Office Hours Podcast: S5E16 - May Release Train Shift & What's Coming in Spring Boot 4.1

Join Dan Vega and DaShaun Carter for the latest updates from the Spring Ecosystem. In this episode, Dan and DaShaun break down the recently announced shift of the May release train from May 11-22 to June 1-5, and what that means for your upgrade planning across the Spring portfolio. They also dig...

GHSA-43G7-CWR8-Q3JH OpenTelemetry eBPF Instrumentation: Memcached payload length overflow can crash OBI

Summary A remotely reachable integer overflow in OBI's memcached text protocol parser can crash the OBI process and cause denial of service. When parsing memcached storage commands such as set, add, replace, append, prepend, or cas, OBI accepts extremely large values and adds the payload delimite...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the memcached text protocol parser when handling storage commands with extremely large values. An attacker can cause the process to crash and disrupt telemetry collection by sending crafted memcached...

OpenTelemetry eBPF Instrumentation: MongoDB parser panics on malformed wire messages

Summary Malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated...

GHSA-962Q-HWM5-52X5 OpenTelemetry eBPF Instrumentation: CappedConcurrentHashMap leaks keys after removals

Summary The custom CappedConcurrentHashMap introduced for Java TLS state tracking never removes keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, repeated connection churn can therefore grow the queue without bound and exhaust heap memory. Details Th...

GHSA-R6C9-G6Q5-QRF9 OpenTelemetry eBPF Instrumentation: CPU-mismatch fallback uses 256-byte buffer with 8KB size

Summary The per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can read beyond the fallback buffer and leak adjacent memory into telemetry. Details...

GHSA-89C6-VPCJ-7VJ4 OpenTelemetry eBPF Instrumentation: Unbounded BPF internal metrics replay can exhaust CPU

Summary OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the metrics exporter to spend excessive CPU time in a tight loop every collection interval. Details The vulnerable loop is in...

Excessive Iteration

Overview Affected versions of this package are vulnerable to Excessive Iteration in the prombpf.go process. An attacker can cause excessive CPU consumption by generating a high volume of probe activity, which leads to unbounded replay of internal metrics during each collection interval. Remediati...

GHSA-WP73-MWGF-4JQ9 OpenTelemetry eBPF Instrumentation: Unsafe fastelf parsing allows malformed ELF to crash agent

Summary OBI's replacement ELF parser trusts section offsets, counts, and string offsets from the executable file. A crafted local ELF can make OBI dereference invalid section pointers or slice past string tables, causing the agent to panic while determining the process language. Details...
