{"cve":"CVE-2026-107293","nvd":{"published":"2026-10-08T17:17:14.933","modified":"2026-10-13T14:30:39.803","status":"Analyzed","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":2.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-212","CWE-532"],"references":["https://github.com/pydantic/pydantic-ai/commit/fe9dbed7b7ccf7e7128b5786886e4441f6f5594f","https://github.com/pydantic/pydantic-ai/pull/7357","https://github.com/pydantic/pydantic-ai/releases/tag/v2.27.1","https://github.com/pydantic/pydantic-ai/security/advisories/GHSA-3gh4-cghq-f8v4"],"products":["pydantic:pydantic_ai"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107293","score":0.00297,"percentile":0.22129,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3gh4-cghq-f8v4","url":"https://osv.dev/vulnerability/GHSA-3gh4-cghq-f8v4","summary":"Pydantic AI OpenTelemetry instrumentation: retry prompt content is not redacted when `include_content=False`","modified":"2026-10-15T14:56:22.971904466Z","packages":[{"ecosystem":"PyPI","name":"pydantic-ai","purl":"pkg:pypi/pydantic-ai","ranges":[">=0.3.4 <1.107.4"],"fixed":["1.107.4"]},{"ecosystem":"PyPI","name":"pydantic-ai","purl":"pkg:pypi/pydantic-ai","ranges":[">=2.0.0b1 <2.27.1"],"fixed":["2.27.1"]},{"ecosystem":"PyPI","name":"pydantic-ai-slim","purl":"pkg:pypi/pydantic-ai-slim","ranges":[">=0.3.4 <1.107.4"],"fixed":["1.107.4"]},{"ecosystem":"PyPI","name":"pydantic-ai-slim","purl":"pkg:pypi/pydantic-ai-slim","ranges":[">=2.0.0b1 <2.27.1"],"fixed":["2.27.1"]}]},{"id":"PYSEC-2026-4274","url":"https://osv.dev/vulnerability/PYSEC-2026-4274","summary":"Pydantic AI OpenTelemetry instrumentation: retry prompt content is not redacted when `include_content=False`","modified":"2026-10-15T14:56:22.971904466Z","packages":[{"ecosystem":"PyPI","name":"pydantic-ai","purl":"pkg:pypi/pydantic-ai","ranges":[">=0.3.4 <1.107.4",">=2.0.0b1 <2.27.1"],"fixed":["1.107.4","2.27.1"]}]},{"id":"PYSEC-2026-4283","url":"https://osv.dev/vulnerability/PYSEC-2026-4283","summary":"Pydantic AI OpenTelemetry instrumentation: retry prompt content is not redacted when `include_content=False`","modified":"2026-10-15T14:56:22.971904466Z","packages":[{"ecosystem":"PyPI","name":"pydantic-ai-slim","purl":"pkg:pypi/pydantic-ai-slim","ranges":[">=0.3.4 <1.107.4",">=2.0.0b1 <2.27.1"],"fixed":["1.107.4","2.27.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
