CVE-2026-48862

Mint’s HTTP/2 client is vulnerable to unbounded growth of conn.streams due to PUSH_PROMISE handling. In Mint.HTTP2.decode_push_promise_headers_and_add_response/5, a :reserved_remote entry is created for every promised stream ID, and assert_valid_promised_stream_id/2 only checks that the ID is eve...

Name of the Vulnerable Software and Affected Versions mint versions 0.2.0 through 1.8.x Description An issue exists where attacker-controlled HTTP/2 servers can exhaust memory in a client via PUSH PROMISE flooding. In the file lib/mint/http2.ex, the function decode push promise headers and add...

Mint 安全漏洞

Mint is a functional underlying HTTP client library developed by Elixir Mint. Versions of Mint from 0.2.0 to 1.9.0 contained security vulnerabilities. These vulnerabilities stemmed from the HTTP/2 server’s ability to insert unlimited entries through the PUSHPROMISE frame, which could lead to memo...

vm2 sandbox escape via JSPI-backed Promise `.finally()` species bypass

Summary A sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI WebAssembly.promising / WebAssembly.Suspending. In the tested configuration, a JSPI-backed Promise can reach...

CVE-2026-44001

A flaw was found in vm2 before 3.11.0. Sandboxed code can crash the host Node.js process via a Promise constructor that triggers an unhandled rejection propagating to the host; the CVE-2026-22709 fix only sanitized .then/.catch callbacks, not the executor path. Fixed in 3.11.0...

CVE-2026-44001

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 v3.10....

CVE-2026-44000

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox boundary violation in vm2 allows host object identity to cross into the sandbox through host Promise resolution. When a host-side Promise that resolves to a host object is exposed to the sandbox, the value delivered to the...
