Allocation of Resources Without Limits or Throttling vulnerability in ueberauth guardian Guardian.Permissions module allows a denial of service via BEAM atom-table exhaustion. This vulnerability is associated with program file lib/guardian/permissions.ex and program routines...

CVE-2026-55733

Allocation of Resources Without Limits or Throttling in ueberauth guardian allows denial of service via unbounded atom creation from attacker-controlled binary input. Guardian.Permissions.AtomEncoding encodes permission scopes by passing arbitrary binaries to String.toatom/1. When encode/3 in...

CVE-2026-54894

Allocation of Resources Without Limits or Throttling in ueberauth guardian allows denial of service via unbounded atom creation from attacker-influenced binary input. Guardian.Plug.Keys derives connection and session namespace keys by passing arbitrary binaries to String.toatom/1. basekey/1 in...

CVE-2026-55734

CVE-2026-55734 affects guardian: from 2.0.0 before 2.4.1. The vulnerability lies in Guardian.Permissions.encode_permissions!/1 (Elixir) where each map key is converted to an atom via String.to_atom(to_string(k)) before validation. If a key has an integer value, the encoding path bypasses validati...

CVE-2026-55734 guardian atom exhaustion in Guardian.Permissions.encode_permissions!/1

Allocation of Resources Without Limits or Throttling vulnerability in ueberauth guardian Guardian.Permissions module allows a denial of service via BEAM atom-table exhaustion. This vulnerability is associated with program file lib/guardian/permissions.ex and program routines...

CVE-2026-55733

CVE-2026-55733 concerns Guardian permissions AtomEncoding: when encoding permission scopes, external binary inputs are passed to String.to_atom/1 without allow-list checks, causing unbounded atom creation. Each unseen binary mints a permanent BEAM atom; the atom table is finite (~1,048,576 entrie...

CVE-2026-59250

Classic buffer overflow in the Erlang/OTP megaco flex scanner C driver allows a remote unauthenticated attacker to corrupt the driver's memory and potentially achieve remote code execution or a denial-of-service crash by sending a single text-encoded H.248/Megaco message containing an oversized...

CVE-2026-58227

The Erlang/OTP ssl application does not detect cycles when reconstructing an incomplete peer certificate chain during a TLS or DTLS handshake. In sslcertificate:handleincompletechain/5, the received chain is passed to sslcertificate:buildcertificatechain/5, which walks issuer relationships via...

CVE-2026-56811

The CVE-2026-56811 issue affects the Phoenix framework (Phoenix.Socket) where transports (WebSocket/LongPoll) allow an unbounded number of channel joins per transport, enabling a single unauthenticated client to exhaust BEAM processes and cause a denial-of-service across the node. Root cause is l...

CVE-2026-48853

A flaw was found in the grpc component of elixir-grpc. This vulnerability allows unauthenticated attackers to send specially crafted messages, leading to two critical outcomes. First, it can cause a Denial of Service DoS by crashing the Erlang virtual machine BEAM node. Second, under certain...

EEF-CVE-2026-54888 Uncontrolled recursion over deeply nested Markdown crashes the BEAM in mdex

Summary Uncontrolled Recursion vulnerability in leandrocp mdex allows denial of service via deeply nested Markdown input. mdex converts between an Elixir %MDEx.Document struct and Comrak's internal AST using two mutually recursive Rust functions, ex\document\to\comrak\ast and...
