Tesla vulnerable to atom exhaustion via untrusted URL scheme

Summary In the Mint adapter for the Tesla HTTP client library, Tesla.Adapter.Mint.openconn/2 passes the URL scheme of every outgoing request through String.toatom/1 with no allow-list validation. Because BEAM atoms are permanent never garbage-collected and the atom table is bounded at roughly...

CVE-2026-53426

Allocation of Resources Without Limits or Throttling vulnerability in leandrocp MDEx allows Excessive Allocation. MDEx.parsedocument/2 accepts a :json, json source. In lib/mdex.ex, the private jsontonode/1 function passes the attacker-controlled nodetype value to Module.concat/1, which calls...

CVE-2026-53426

Summary: CVE-2026-53426 affects the MDEx JSON parser. An attacker-controlled node_type in JSON fed to MDEx.parse_document/2 causes repeated String.to_atom/1 calls via Module.concat/1, creating permanent atoms and eventually exhausting the BEAM atom table. Consequence is unauthenticated denial-of-...

Hackney vulnerable to atom-table exhaustion via unrecognized URL schemes

Summary CVE-2026-47067 is an atom table exhaustion vulnerability CWE-770 in hackney's URL parser src/hackneyurl.erl. hackneyurl:parseurl/1 converts every URL scheme it encounters into a BEAM atom via binarytoatom/2. Because BEAM atoms are never garbage-collected and the atom table has a hard limi...
