Newly released CVEs across every platform — sleek to read, verbose on demand, and served raw as markdown for AI and agent ingestion. Severity reads as depth: the deeper the contact, the graver the threat.
Depth = severity + exploitation
CVE-2026-106071Low· 3.6PoCA flaw in Node.js Permission Model filesystem enforcement can grant access to paths that do not match a wildcard `--allow-fs-read` or `--allow-fs-write` rule. When the requested path is shorter than the prefix of a wildcard grant, the r…
CVE-2026-106072Medium· 6.7PoCA flaw in Node.js TLS hostname verification allows a certificate with only a DNS SAN to authenticate an IP endpoint when the client connects using a non-canonical IPv4 spelling, such as `0177.0.0.1`, `0x7f.0.0.1`, `2130706433` or `127.1`…
CVE-2026-106073Low· 3.3PoCA flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync()` without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered `fs.realpathSync.native()`. As a result, c…
CVE-2026-106070Low· 3.7PoCA flaw in the Node.js `zlib.ZipFile` API can cause it to return bytes that do not belong to the requested entry after the local and central header validation fails. When `zipEntry.modified` is read on an archive whose local header does …
CVE-2026-105483High· 7.4PoCA flaw in Node.js TLS hostname verification allows a certificate without a matching IP address SAN to authenticate a connection to an IPv4 address when the host is written with non-ASCII characters, such as fullwidth digits (`１２７.0.0.1`)…
CVE-2026-106074Medium· 4.8PoCA flaw in Node.js `crypto` causes the internal entropy caches used by `crypto.randomUUID()`, `crypto.randomUUIDv7()`, and `crypto.randomInt()` to be saved into user-land startup snapshots (`--build-snapshot`) and single executable applic…
CVE-2026-106069High· 7.4PoCA flaw in Node.js TLS hostname verification can cause a server certificate to be validated against a different IP address than the one the client connected to, when the host is a non-canonical IPv4 literal with a leading zero, such as `0…
CVE-2026-105482High· 7.4PoCA flaw in Node.js DNS resolution allows hostnames containing a NUL byte to be silently truncated by the dns.resolve*() functions and dns.reverse(). This is an incomplete fix of CVE-2026-48930, which only covered dns.lookup() and the net/…
CVE-2026-105481Medium· 6.5PoCA flaw in Node.js HTTP Agent connection reuse can cause a client to accept as valid a response that was sent before the client has sent the request. This is an incomplete fix of CVE-2026-48931. The guard that destroys idle keep-alive so…
CVE-2026-84890Medium· 5.9undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding header. While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no confi…
CVE-2026-85152High· 7.4undici 8.10.0 omits the destination origin from the cache and request-deduplication keys when the cache or deduplicate interceptor is composed directly onto a Client or Pool. Because the internal cache key falls back to an empty origin s…
CVE-2026-85024Medium· 5.9undici bundles a WebSocket client whose permessage-deflate size-limit cleanup removes all listeners from the internal zlib inflate stream, including its error listener, while that stream can still emit. When a remote peer sends a compres…
CVE-2026-85014Medium· 5.9undici's experimental WebSocketStream client crashes the whole Node.js process when a remote peer closes the TCP connection without a WebSocket close handshake. On an unclean close the internal socket-close handler calls abort on the wri…
CVE-2026-85008Low· 3.7undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as POST, PUT, or DELETE is n…
CVE-2026-84961High· 7.4undici's BalancedPool constructor passes its entire options object through an internal deep-clone that serializes and reparses the value as JSON. Because JSON cannot represent functions, any function-valued TLS option, such as a caller-s…
CVE-2026-84947Low· 3.7⚖ disputedundici's dump interceptor reads and discards a response body up to a configurable maximum size. When a response declares a Content-Length that exceeds the maximum, the interceptor aborts cleanly, but when a response has no Content-Length…
CVE-2026-84933Medium· 6.5undici's cache interceptor does not handle the Set-Cookie response header anywhere in its cache path, so it neither refuses to store nor strips that header. In shared cache mode, which is the default, an otherwise cacheable response that…
CVE-2026-19534High· 7.5undici's WebSocket client crashes the whole Node.js process during the opening handshake when a server responds with a subprotocol that the client never requested. A default WebSocket connection sends no subprotocol, but if the server's …
CVE-2026-18540Low· 3.7undici's retry interceptor can append the body of a ranged retry response to bytes already delivered from an earlier partial response while still presenting the original response's status and headers. This happens when an upstream server…
CVE-2026-18149Medium· 5.9undici's retry handler can leave an already-exposed response body pending forever. When a server returns a successful response that declares a Content-Length, sends only part of the body, and closes the connection, the retry handler retr…
CVE-2026-48931Low· 3.7A flaw in Node.js HTTP Agent can cause a client to accept as valid a response that is send before the client has sent the request. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 2…
CVE-2026-21711Medium· 5.3A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket (UDS) server operations without the required permission checks, while all comparable network paths correctly enforce them. As a result, code running unde…
CVE-2026-21710High· 7.5PoCA flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received with a header named `__proto__` and the application accesses `req.headersDistinct`. When this occurs, `dest["__proto__"]` resolves to `O…
CVE-2026-21712Medium· 6.5A 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.
CVE-2026-21717Medium· 5.9PoCA 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, …
The beta is over. VulnSea now runs at vulnsea.com, every old beta link redirects to the same page, and your account, API keys and watchlists came with it. Plus a round of hardening, faster pages, and new request limits agents should know about.
A summary of everything that shipped over the last two weeks — the whole corpus is open, agents get change feeds, alias resolution and EPSS movers, and the data now includes CVE.org, vendor CSAF, aggregated exploits and per-source scores.
A step-by-step guide to plugging VulnSea into automated and agentic workflows — poll the delta, triage without burning tokens, match an SBOM, and let an MCP-native model do the reasoning.
