CVE-2026-1605 (GCVE-0-2026-1605)
Vulnerability from cvelistv5 – Published: 2026-03-05 09:39 – Updated: 2026-06-30 12:07
VLAI
EPSS
Summary
In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed.
This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response.
In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak.
Severity
7.5 (High)

Title
Apache ZooKeeper: Reverse-DNS fallback enables hostname verification bypass in ZooKeeper ZKTrustManager
Summary
Hostname verification in Apache ZooKeeper ZKTrustManager falls back to reverse DNS (PTR) when IP SAN validation fails, allowing attackers who control or spoof PTR records to impersonate ZooKeeper servers or clients with a valid certificate for the PTR name. It's important to note that attacker must present a certificate which is trusted by ZKTrustManager which makes the attack vector harder to exploit. Users are recommended to upgrade to version 3.8.6 or 3.9.5, which fixes this issue by introducing a new configuration option to disable reverse DNS lookup in client and quorum protocols.

Title
Netty: HTTP Request Smuggling via Chunked Extension Quoted-String Parsing
Summary
Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, Netty incorrectly parses quoted strings in HTTP/1.1 chunked transfer encoding extension values, enabling request smuggling attacks. Versions 4.1.132.Final and 4.2.10.Final fix the issue.
Severity

Title
Netty HTTP/2 CONTINUATION Frame Flood DoS via Zero-Byte Frame Bypass
Summary
Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, a remote user can trigger a Denial of Service (DoS) against a Netty HTTP/2 server by sending a flood of `CONTINUATION` frames. The server's lack of a limit on the number of `CONTINUATION` frames, combined with a bypass of existing size-based mitigations using zero-byte frames, allows an user to cause excessive CPU consumption with minimal bandwidth, rendering the server unresponsive. Versions 4.1.132.Final and 4.2.10.Final fix the issue.

Summary
Jackson Core: Document length constraint bypass in blocking, async, and DataInput parsers
Details
Summary
Jackson Core 3.x does not consistently enforce StreamReadConstraints.maxDocumentLength. Oversized JSON documents can be accepted without a StreamConstraintsException in multiple parser entry points, which allows configured size limits to be bypassed and weakens denial-of-service protections.
Details
Three code paths where maxDocumentLength is not fully enforced:
1. Blocking parsers skip validation of the final in-memory buffer
Blocking parsers validate only previously processed buffers, not the final in-memory buffer:
ReaderBasedJsonParser.java:255UTF8StreamJsonParser.java:208
Relevant code:
_currInputProcessed += bufSize;
_streamReadConstraints.validateDocumentLength(_currInputProcessed);
This means the check occurs only when a completed buffer is rolled over. If an oversized document is fully contained in the final buffer, parsing can complete without any document-length exception.
2. Async parsers skip validation of the final chunk on end-of-input
Async parsers validate previously processed chunks, but do not validate the final chunk on end-of-input:
NonBlockingByteArrayJsonParser.java:49NonBlockingByteBufferJsonParser.java:57NonBlockingUtf8JsonParserBase.java:75
Relevant code:
_currInputProcessed += _origBufferLen;
_streamReadConstraints.validateDocumentLength(_currInputProcessed);
public void endOfInput() {
_endOfInput = true;
}
endOfInput() marks EOF but does not perform a final validateDocumentLength(...) call, so an oversized last chunk is accepted.
3. DataInput parser path does not enforce maxDocumentLength at all
JsonFactory.java:457
Relevant construction path:
int firstByte = ByteSourceJsonBootstrapper.skipUTF8BOM(input);
return new UTF8DataInputJsonParser(readCtxt, ioCtxt,
readCtxt.getStreamReadFeatures(_streamReadFeatures),
readCtxt.getFormatReadFeatures(_formatReadFeatures),
input, can, firstByte);
UTF8DataInputJsonParser does not call StreamReadConstraints.validateDocumentLength(...), so maxDocumentLength is effectively disabled for createParser(..., DataInput) users.
Note: This issue appears distinct from the recently published nesting-depth and number-length constraint advisories because it affects document-length enforcement.
PoC

import java.nio.charset.StandardCharsets;
import tools.jackson.core.JsonParser;
import tools.jackson.core.ObjectReadContext;

public class Poc {
public static void main(String[] args) throws Exception {
JsonFactory factory = JsonFactory.builder()

.build();
byte[] doc = "{\"a\":1,\"b\":2}".getBytes(StandardCharsets.UTF_8);
try (JsonParser p = factory.createNonBlockingByteArrayParser(ObjectReadContext.empty())) {
ByteArrayFeeder feeder = (ByteArrayFeeder) p.nonBlockingInputFeeder();
feeder.feedInput(doc, 0, doc.length);
feeder.endOfInput();
while (p.nextToken() != null) { }
}
System.out.println("Parsed successfully");
}
}
- Expected result: Parsing should fail because the configured document-length limit is 10, while the input is longer than 10 bytes.
- Actual result: The document is accepted and parsing completes.

import java.nio.charset.StandardCharsets;

byte[] doc = "{\"a\":1,\"b\":2}".getBytes(StandardCharsets.UTF_8);
try (JsonParser p = factory.createParser(new ByteArrayInputStream(doc))) {
while (p.nextToken() != null) { }
}
System.out.println("Parsed successfully");
}
}
Impact
Applications that rely on maxDocumentLength as a safety control for untrusted JSON can accept oversized inputs without error. In network-facing services this weakens an explicit denial-of-service protection and can increase CPU and memory consumption by allowing larger-than-configured request bodies to be processed.

Summary
jose4j is vulnerable to DoS via compressed JWE content
Details
In jose4j before 0.9.6, an attacker can cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression.

Vulnerability from github – Published: 2026-03-04 21:23 – Updated: 2026-03-06 21:58
VLAI
Summary
jackson-core has Nesting Depth Constraint Bypass in `UTF8DataInputJsonParser` potentially allowing Resource Exhaustion
Details
Summary
The UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints.
A similar issue was found in ReaderBasedJsonParser.
This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS).
The related fix for com.fasterxml.jackson.core:jackson-core, CVE-2025-52999, was not fully applied to tools.jackson.core:jackson-core until the 3.1.0 release. It is recommended that 3.0.x users upgrade.
Patches
jackson-core contains a configurable limit for how deep Jackson will traverse in an input document. This check was missing in a few places in tools.jackson.core:jackson-core.
The change is in https://github.com/FasterXML/jackson-core/pull/1554. jackson-core will throw a StreamConstraintsException if the limit is reached.
jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs.
Workarounds
Users should avoid parsing input files from untrusted sources.

Summary
jackson-core: Number Length Constraint Bypass in Async Parser Leads to Potential DoS Condition
Details
Summary
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.

return sb.toString().getBytes(StandardCharsets.UTF_8);
}
}
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.

Summary
Logback allows an attacker to instantiate classes already present on the class path
Details
ACE vulnerability in configuration file processing by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.
The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a configuration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.
