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...

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...

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...

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-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...

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...

Name of the Vulnerable Software and Affected Versions OpenTelemetry eBPF Instrumentation versions prior to 0.9.0 Description The Postgres protocol parser incorrectly assumes that BIND message payloads contain a valid NUL-terminated portal name. When processing a crafted empty or unterminated...

CVE-2026-2652

A vulnerability in mlflow/mlflow versions 3.9.0 and earlier allows unauthenticated access to certain FastAPI routes when the server is started with authentication enabled --app-name basic-auth and served via uvicorn ASGI. The FastAPI permission middleware only enforces authentication on /gateway/...

CVE-2026-42602

The CVE affects opentelemetry-collector-contrib’s azureauthextension in versions 0.124.0–0.150.0. The root cause is that Authenticate performs a token equality check against a token minted by the collector’s own credential, using the client-supplied Host header to set the scope, and does not vali...
