  "summary": "pomerium_signature is not verified in middleware in github.com/pomerium/pomerium",
  "details": "### Impact\nSome API endpoints under /.pomerium/ do not verify parameters with pomerium_signature. This could allow modifying parameters intended to be trusted to Pomerium. \n\nThe issue mainly affects routes responsible for sign in/out, but does not introduce an authentication bypass.\n\n### Patches\nPatched in v0.13.4\n\n### For more information\nIf you have any questions or comments about this advisory\n* Open an issue in [pomerium](http://github.com/pomerium/pomerium)\n* Email us at [security@pomerium.com](mailto:security@pomerium.com)",
