CVE-2026-48597Public exploitNetwork attack vectorHinoki check available

VM crash via unbounded URL-scheme atom creation

Published Jun 2, 2026 · Updated Jun 2, 2026

Resource exhaustion in the Mint adapter in Tesla 1.3.0 through 1.18.2 allows attackers to crash the BEAM VM via crafted URL schemes. Tesla.Adapter.Mint.open_conn/2 passes every parsed scheme to String.to_atom/1 without an allowlist, permanently interning each novel value. Reachability requires untrusted request URLs or an attacker-controlled redirect when FollowRedirects is enabled; exhausting the bounded atom table terminates the application VM.
