Doc Text:	A flaw was found in pydantic-ai. An information disclosure vulnerability occurs when OpenTelemetry instrumentation is configured to omit message contents, as retry prompts generated during output validation are still exported to the telemetry backend. A user with read access to telemetry logs can view validation feedback and model outputs that were intended to be suppressed.	Story Points:	---

Description OSIDB Bzimport 2026-10-08 17:01:47 UTC

Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 0.3.4 until 1.107.4 and 2.27.1, OpenTelemetry instrumentation configured with InstrumentationSettings(include_content=False) can export retry prompts outside tool calls in gen_ai.input.messages and pydantic_ai.all_messages. Agents using NativeOutput, PromptedOutput, or output validators on text output can therefore disclose validation feedback, including invalid model values quoted by that feedback, to readers of the telemetry backend. Tool-call retries and deployments that do not use include_content=False are not affected by this specific path. This issue is fixed in versions 1.107.4 and 2.27.1.
