CVE-2026-56810— Elixir Mint Mint 资源管理错误漏洞

mint buffers an entire chunked response chunk in memory in Mint.HTTP1.decode_body/5

Allocation of Resources Without Limits or Throttling vulnerability in elixir-mint mint (Mint.HTTP1 module) allows a denial of service via an oversized chunked transfer-encoded response. This vulnerability is associated with program files lib/mint/http1.ex and program routines 'Elixir.Mint.HTTP1':decode_body/5, 'Elixir.Mint.HTTP1':add_body_to_buffer/2. When Mint decodes a chunked HTTP response body, it accumulates each partial fragment of the current chunk in the connection's data_buffer (an unbounded iolist) via add_body_to_buffer/2 and does not emit the data to the caller until the full declared chunk length has been received. The chunk size is taken directly from the server and parsed with no upper bound, so a malicious or compromised server can announce one enormous chunk (for example a size line of 7FFFFFFF, about 2 GiB) and then send the body bytes slowly without ever completing the chunk. The client buffers every received byte while it waits for a completion that never arrives, and because no data responses are produced until the chunk finishes, a caller that otherwise streams large content-length bodies safely gains no protection. An unauthenticated remote server (reachable whenever a client follows redirects, fetches user-supplied URLs, or processes webhooks) can drive the client's memory arbitrarily high and trigger an out-of-memory condition. This issue affects mint: from 0.5.0 before 1.9.1.

不加限制或调节的资源分配

Elixir Mint Mint 资源管理错误漏洞

elixir-mint mint是elixir-mint的HTTP客户端库。 Elixir Mint Mint 0.5.0版本至1.9.1之前版本存在资源管理错误漏洞，该漏洞源于资源未限速（Mint.HTTP1模块）问题，当解码分块传输编码响应时，未对块大小设限，导致恶意或受感染的服务器可造成拒绝服务。
