Answer in brief
CVE-2026-48597 records a High severity (CVSS 8.2) vulnerability in Atom table exhaustion via untrusted URL scheme in Tesla.Adapter.Mint. The current sources do not mark it as known exploited. The current feed maps tesla (erlang), elixir-tesla/elixir-tesla/tesla (generic), elixir-tesla/tesla (generic). Check affected ranges and fixed versions before updating.

Allocation of Resources Without Limits or Throttling vulnerability in elixir-tesla tesla allows denial of service via atom table exhaustion in Tesla.Adapter.Mint. Tesla.Adapter.Mint.open_conn/2 converts the URL scheme of every outgoing request to a BEAM atom via String.to_atom(uri.scheme) with no allow-list validation. BEAM atoms are never garbage-collected and the atom table is bounded (approximately 1,048,576 entries by default). An attacker who can influence the URL of a Tesla request — either via an application-level URL-forwarding feature (webhook, proxy, importer) or via a Location header returned by a server when Tesla.Middleware.FollowRedirects is in the pipeline — can mint one fresh permanent atom per request by varying the scheme string. After enough requests the atom table fills and the VM crashes, taking down the entire application. This issue affects tesla: from 1.3.0 before 1.18.3.
