  "summary": "OpenID Connect client Atom Exhaustion in provider configuration worker ets table location",
  "details": "### Impact\n\nDOS by Atom exhaustion is possible by calling `oidcc_provider_configuration_worker:get_provider_configuration/1` or `oidcc_provider_configuration_worker:get_jwks/1`.\n\nSince the name is usually provided as a static value in the application using `oidcc`, this is unlikely to be exploited.\n\n### Details\n\nExample to illustrate the vulnerability.\n\n```erlang\n{ok, Claims} =\n  oidcc:retrieve_userinfo(\n    Token,\n    myapp_oidcc_config_provider,\n    <<\"client_id\">>,\n    <<\"client_secret\">>,\n    #{}\n  )\n```\n\nThe vulnerability is present in `oidcc_provider_configuration_worker:get_ets_table_name/1`.\nThe function `get_ets_table_name` is calling `erlang:list_to_atom/1`.\n\nhttps://github.com/erlef/oidcc/blob/018dbb53dd752cb1e331637d8e0e6a489ba1fae9/src/oidcc_provider_configuration_worker.erl#L385-L388\n\nThere might be a case (Very highly improbable) where the 2nd argument of\n`oidcc_provider_configuration_worker:get_*/1` is called with a different atom each time which eventually leads to\nthe atom table filling up and the node crashing.\n\n### Patches\n\nPatched in `3.0.2`, `3.1.2` & `3.2.0-beta.3`\n\n### Workarounds\n\nMake sure only valid provider configuration worker names are passed to the functions.\n\n### References\n\n* https://erlef.github.io/security-wg/secure_coding_and_deployment_hardening/atom_exhaustion.html\n",
