From 1.77.0 until 1.107.2 and 2.24.0, web_fetch_tool, the WebFetch local fallback, and remote FileUrl media downloads buffer the complete HTTP response body before enforcing content-size controls. An attacker-influenced URL can stream an arbitrarily large response that exhausts process memory and crashes the worker; affected media types include ImageUrl, DocumentUrl, VideoUrl, and AudioUrl. SSRF protections remain effective, and the impact is limited to availability. This issue is fixed in versions 1.107.2 and 2.24.0."}], "lastModified": "2026-10-13T13:49:02.473", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:pydantic:pydantic_ai:*:*:*:*:*:python:*:*", "vulnerable": true, "matchCriteriaId": "F6DF9B54-930E-407D-B33D-CCCB5E5349CD", "versionEndExcluding": "1.107.2", "versionStartIncluding": "1.77.0"}, {"criteria": "cpe:2.3:a:pydantic:pydantic_ai:*:-:*:*:*:python:*:*", "vulnerable": true, "matchCriteriaId": "213182E9-509B-428C-987E-50233543D4EC", "versionEndExcluding": "2.24.0", "versionStartIncluding": "2.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
