OpenTelemetry.Resources.Azure has an unbounded HTTP response body read
CVE-2026-41483 · GHSA-vc24-j8c5-2vw4
- Affected
- NuGet opentelemetry.resources.azure <= 1.15.0-beta.1
- Fixed in
- 1.15.1-beta.1· Vendor fix available
- Issue
- OpenTelemetry.Resources.Azure reads unbounded HTTP response bodies from the Azure VM remote instance metadata service endpoint into memory. This would allow an attacker-controlled endpoint or one acting as a Man-in-the-Middle (MitM) to cause excessive memory allocation and possible process termination (via Out of Memory (OOM)). Details The AzureVmMetaDataRequestor class makes HTTP requests to the relevant Azure VM instance metadata service (http://169.254.169.254) to obtain metadata about the running process and its infrastructure. An attacker who controls the configured endpoint, or who can intercept traffic to them (MiTM), 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. Impact Denial of Service (DoS). An attacker can destabilize or crash the application by forcing unbounded memory…
Recommended action: Upgrade to 1.15.1-beta.1 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
