Chainguard: py3.10-opentelemetry-semantic-conventions-ai: security update to 0.5.1-r2

medium Tenable Self-Hosted Container Security Plugin ID 477150

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenTelemetry Python provides the Python API and SDK for OpenTelemetry. Prior to 1.45.1, the
 opentelemetry-api function TraceState.from_header in opentelemetry/trace/span.py, reached through
 TraceContextTextMapPropagator.extract, parses inbound W3C tracestate headers with an unbounded optional-
 whitespace regular expression. A malformed header containing a long run of spaces or tabs without a
 following comma causes quadratic backtracking before the member-count limit is applied. Services using the
 default W3C Trace Context propagator can therefore spend excessive CPU time on one unauthenticated request
 when the HTTP server, parser, gateway, or custom carrier accepts a sufficiently large header. The
 processing can occupy a synchronous worker or delay unrelated requests on the same asynchronous event
 loop. The impact is limited to availability and does not expose or modify telemetry data or allow code
 execution. This issue is fixed in version 1.45.1. (CVE-2026-114603)

Solution

Update the py3.10-opentelemetry-semantic-conventions-ai library and its related packages to version 0.5.1-r2 or later.
