A flaw in Node.js node:sqlite allows a stale StatementSyncIterator created through DatabaseSync#createTagStore() to continue executing a cached prepared statement after it has been reset and rebound with new parameters. SQLTagStore resets cached statements using sqlite3reset() directly, bypassing the iterator invalidation mechanism introduced for StatementSync in recent releases This vulnerability affects Node.js 22.x, 24.x, and 26.x.
An incomplete fix has been identified in Node.js: HTTPS Agent TLS session reuse skips hostname verification across identity policies (incomplete fix of CVE-2026-48934). This vulnerability affects Node.js 22.x, 24.x, and 26.x.
A flaw in Node.js TLS host verification can cause an attacker to bypass certification validation.
This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
A flaw in Node.js TLS hostname handling can cause Node.js unicode dot separator handling can lead to tls wildcard-depth authentication bypass due to resolver and verifier hostname normalization mismat.
This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations.
This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
A flaw in Node.js HTTP/2 server API can cause servers to keep accepting data even after sending a GOAWAY frame. This vulnerability affects two supported release lines: Node.js 22 and Node.js 24.

Security researchers disclosed multiple critical vm2 sandbox escape vulnerabilities this week, including CVE-2026-26956 affecting Node.js 25. The flaws allow attackers running untrusted JavaScript inside vm2 to escape the sandbox and execute arbitrary code on the host system.

A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior could be exploited as a timing oracle to infer HMAC values.
Node.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional design decision.
This vulnerability affects 20.x, 22.x, 24.x, and 25.x.
A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly degrade performance of the Node.js process.
The most common trigger is any endpoint that calls JSON.parse() on attacker-controlled input, as JSON parsing automatically internalizes short strings into the affected hash table.
This vulnerability affects 20.x, 22.x, 24.x, and 25.x.
A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync.native() without the required read permission checks, while all comparable filesystem functions correctly enforce them.
As a result, code running under --permission with restricted --allow-fs-read can still use fs.realpathSync.native() to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.
This vulnerability affects 20.x, 22.x, 24.x, and 25.x processes using the Permission Model where --allow-fs-read is intentionally restricted.
An incomplete fix for CVE-2024-36137 leaves FileHandle.chmod() and FileHandle.chown() in the promises API without the required permission checks, while their callback-based equivalents (fs.fchmod(), fs.fchown()) were correctly patched.
As a result, code running under --permission with restricted --allow-fs-write can still use promise-based FileHandle methods to modify file permissions and ownership on already-open file descriptors, bypassing the intended write restrictions.
This vulnerability affects 20.x, 22.x, 24.x, and 25.x processes using the Permission Model where --allow-fs-write is intentionally restricted.
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up.
This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
A flaw in Node.js URL processing causes an assertion failure in native code when url.format() is called with a malformed internationalized domain name (IDN) containing invalid characters, crashing the Node.js process.
