Name of the Vulnerable Software and Affected Versions OpenTelemetry-Go versions 1.36.0 through 1.40.0 Description The OpenTelemetry-Go implementation is susceptible to a remote request amplification issue due to the way it handles multi-value baggage headers. Specifically, the extractMultiBaggage...
OpenTelemetry-Go security vulnerabilities
OpenTelemetry-Go is an open-source developer toolkit developed by OpenTelemetry - CNCF. Versions of OpenTelemetry-Go from 1.36.0 to 1.40.0 contain security vulnerabilities. These vulnerabilities stem from the independent parsing of each header field value within a multi-value baggage header and t...
CVE-2026-29181: Allocation of Resources Without Limits or Throttling
OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations by sending many baggage: header lines...
SUSE CVE-2026-31838
Istio is an open platform to connect, manage, and secure microservices. Prior to 1.29.1, 1.28.5, and 1.27.8, a vulnerability in Envoy RBAC header matching could allow authorization policy bypass when policies rely on HTTP headers that may contain multiple values. An attacker could craft requests...
BIT-ENVOY-2026-26308 Envoy has an RBAC Header Validation Bypass via Multi-Value Header Concatenation
Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, the Envoy RBAC Role-Based Access Control filter contains a logic vulnerability in how it validates HTTP headers when multiple values are present for the same header name. Instead of validating eac...
curl: Curl_compareheader() fails to match multi-value HTTP headers
Summary Curlcompareheader in lib/http.c fails to scan the full value of HTTP headers for substring matches. Due to an incorrect loop condition, only the first byte position of the header value is checked. This causes curl to miss connection options like close when they appear as non-first tokens ...

CVE-2026-26308
Envoy CVE-2026-26308 affects the Envoy RBAC filter. The issue arises from how multiple HTTP header values are validated: instead of validating each value separately, Envoy concatenates all values into a single comma-separated string, allowing bypass of Deny rules under RBAC. Affects versions prio...
