CVE-2026-86237
openagents-org openagents http.py test_default_model server-side request forgery
Description

A vulnerability was found in openagents-org openagents up to 0.8.19/0.9.3.post20. Impacted is the function test_default_model of the file sdk/src/openagents/sdk/transports/http.py. Performing a manipulation of the argument base_url results in server-side request forgery. The attack may be initiated remotely. The exploit has been made public and could be used. Endpoint and both sinks unchanged since filing; only the file moved (e277dd1a). Maintainer closed as inapplicable yet the identical unguarded code still ships in 0.9.3.post20. Sibling admin endpoints do call the shipped-but-unused-by-this-handler _require_admin().

Solution
Sanitize user-controlled input for base_url to prevent server-side request forgery.
  • Validate and sanitize all external input for base_url.
  • Implement strict allow-lists for permitted base_url values.
  • Update to a version with the vulnerability fixed.
  • Review access controls for admin endpoints.
