Fix CVE-2026-40894: pin OpenTelemetry.Api to 1.15.3#209
Merged
Conversation
Akka.Hosting transitively pulls in OpenTelemetry.Api 1.9.0, which is affected by CVE-2026-40894 (GHSA-g94r-2vxg-569j) - excessive memory allocation in propagation header parsing. The repo treats NuGet audit findings (NU1902) as build errors, so this currently fails CI on every branch, including dev. Add a direct PackageReference to OpenTelemetry.Api in Termina.Demo.Streaming (the only project with the transitive dependency), pinned to the first patched release, 1.15.3. The direct reference overrides the transitive 1.9.0 without changing package resolution for any other project.
