CVE-2026-42549 Flight: Path traversal in `make:controller` CLI creates arbitrary directories outside project root

Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the make:controller CLI command calls mkdir..., recursive: true on a path built from the user-supplied controller name, before Nette's class-name validation runs. The class-file write is correctly rejected by Nette when the name...

CVE-2026-42549

CVE-2026-42549 affects Flight PHP core prior to 3.18.1. The make:controller CLI calls mkdir(..., recursive: true) on a user-supplied controller path before Nette class-name validation, allowing creation of directories outside the project root via ../ traversal. The directory creation side effect ...

CVE-2026-42548 Flight: Reflected XSS via unvalidated JSONP callback in Flight::jsonp()

Flight is an extensible micro-framework for PHP. Prior to 3.18.1, Flight::jsonp concatenates the ?jsonp= query parameter directly into an application/javascript response body without validating that the value is a legal JavaScript identifier. An attacker can inject arbitrary JavaScript that...

CVE-2026-42548

Flight (PHP micro-framework) contains a reflected XSS in Flight::jsonp() prior to version 3.18.1, where the ?jsonp= parameter is concatenated into a JavaScript response without validating the callback name. This allows an attacker to inject arbitrary JavaScript that executes in the response origi...

CVE-2026-44248

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader method is called before the...

CVE-2026-42586

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the Netty Redis codec encoder RedisEncoder writes user-controlled string content directly to the network output buffer without validating or sanitizing CRLF \r\n characters. Since the...

CVE-2026-42582

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final, when decoding header blocks, the non-Huffman branch of io.netty.handler.codec.http3.QpackDecoderdecodeHuffmanEncodedLiteral may execute new bytelength for a string literal before verifying that length byt...

CVE-2026-42583

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength up to 32 MB per block before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload bytes - 22 bytes if...

CVE-2026-42580

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's chunk size parser silently overflows int, enabling request smuggling attacks. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final...

CVE-2026-42579

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's DNS codec does not enforce RFC 1035 domain name constraints during either encoding or decoding. This creates a bidirectional attack surface: malicious DNS responses can exploit t...
