Technical description

basic-ftp is an FTP client for Node.js. Prior to 6.2.4, the MLSD directory-listing parser in src/parseListMLSD.ts uses untrusted fact names from the FTP server as keys in the plain-object factHandlersByName dictionary without checking that the resolved property is an own handler. A fact named __proto__ therefore resolves to Object.prototype, bypasses the missing-handler guard, and is called as though it were a function, producing a TypeError. The error propagates through Client.list() and APIs that depend on it because it is not an FTPError. A malicious or compromised FTP server, or an on-path attacker on a plaintext FTP session, can make the affected operation reject, and the Node.js process terminates under the default behavior in Node.js 15 and later only if the application leaves that rejection unhandled. This issue is fixed in version 6.2.4.

———basic-ftp is an FTP client for Node.js. Prior to 6.2.3, FTPContext.send() throws when a command contains carriage return, line feed, or NUL characters, but calls made from response handlers execute synchronously inside the control socket's data event without an exception boundary. In Client.login(), an attacker-influenced password reaches the PASS command after a server sends a 331 response, and in a resumed download an attacker-influenced remote path reaches the RETR command after a 350 response to REST. The resulting exception does not reject client.access() or downloadTo(), escapes ordinary promise error handling, and terminates the Node.js process, while the validation guard still prevents command injection. This issue is fixed in version 6.2.3.5h CVE-2026-1263435.3 MED

———@hono/node-server allows running the Hono application on Node.js. From 2.0.0 until 2.1.6, the WebSocket upgrade handler waits for the Hono application to finish asynchronous middleware or handler work without first attaching an error listener to the socket. If an unauthenticated client resets the TCP connection during that window, the socket emits an unhandled ECONNRESET error and terminates the Node.js process. If a global uncaughtException handler suppresses termination, the pending upgrade waiter is not released and repeated requests can grow the heap. This affects applications that enable WebSocket support and perform asynchronous work on the upgrade path. This issue is fixed in version 2.1.6.5h CVE-2026-1061468.6 HIG

———In Progress® Telerik® UI for ASP.NET MVC versions `2012.2.710` through `2026.3.1015`, server-side filter processing does not properly validate descriptor types, null values, or stack state in FilterNodeVisitor and does not catch FilterParserException within the affected assembly. An unauthenticated remote attacker can exploit this if the application exposes an endpoint reachable without authentication that accepts crafted filter parameters. Affected requests can trigger uncaught cast, null-reference, or empty-stack exceptions and return HTTP 500. The report does not demonstrate worker-process termination or disruption of unrelated requests. The issue is fixed in version `2026.4.1111`.9h CVE-2026-1238622.9 LOW

——0An uncatchable exception in the Node.js zlib streaming API lets a peer crash a process by disconnecting while data is being compressed. zlib.params() queues a flush and completes its work in that write's callback; if the stream is destroyed first, as pipeline() does when the peer goes away, Writable still invokes the callback with an error, but the callback ignores its arguments and asserts that the native handle still exists. The handle is gone, so an ERR_INTERNAL_ASSERTION is thrown from inside stream internals and bypasses the stream's error event, the params() callback, and the pipeline() callback, terminating the process. An application is affected only if it calls deflate.params() while streaming to a peer, which is uncommon. This vulnerability affects Node.js 26.x, 24.x, and 22.x.9h CVE-2026-1265707.6 HIG

——11Padloc 4.0.0 before 4.3.1 contains a prototype pollution vulnerability that allows SCIM token holders to modify Object.prototype by sending crafted SCIM PATCH paths to ScimServer._handleScimUsersPatch(). Attackers can supply paths like __proto__.x or constructor.prototype.x passed to setPath() to pollute the shared server process, disrupting requests for all other organizations.6h CVE-2026-1265464.3 MED
