CVE-2026-75430_PowerJob_worker_deployContainer_RCE

PowerJob Worker Unauthenticated Remote Code Execution via /worker/deployContainer Arbitrary JAR Loading 1. Summary The PowerJob Worker exposes the deployContainer handler on its HTTP transport port 27777 with no authentication whatsoever. An attacker submits an arbitrary URL; the Worker downloads...

CVE-2026-90466

Path traversal of 'trustedjarpaths' in Impala 4.5.2 allows an attacker-controlled JAR to be loaded via a relative path where the prefix matches a path specified in 'trustedjarpaths'. The startup flag 'trustedjarpaths' references URIs for loading files from local or remote filesystems. Path...

Path traversal of 'trusted jar paths' in Impala 4.5.2 allows an attacker-controlled JAR to be loaded via a relative path where the prefix matches a path specified in 'trusted jar paths'. The startup flag 'trusted jar paths' references URIs for loading files from local or remote filesystems. Path...

Fastjson 1.2.83 Remote Code Execution

Fastjson versions 1.2.68 through 1.2.83 contain a remote code execution vulnerability that can allow an attacker to cause a vulnerable application to load attacker-controlled Java classes. This proof of concept generates a malicious JAR containing a reverse shell payload, serves the JAR over HTTP...

DEBIAN-CVE-2026-12252

In nltk/nltk versions 3.9.3 and earlier, five Stanford interface classes StanfordPOSTagger, StanfordNERTagger, StanfordParser, StanfordDependencyParser, and StanfordNeuralDependencyParser are vulnerable to untrusted JAR code execution. These classes accept user-controllable JAR paths and execute...

EUVD-2026-30512

SzafirHost verifies the signature of the downloaded JAR file using class JarInputStream reading from the beginning of the file, but loads classes using class JarFile/URLClassLoader reading the Central Directory from the end. It can lead to remote code execution by allowing an attacker to combine ...

EUVD-2026-9875

NLTK versions =3.9.2 are vulnerable to arbitrary code execution due to improper input validation in the StanfordSegmenter module. The module dynamically loads external Java .jar files without verification or sandboxing. An attacker can supply or replace the JAR file, enabling the execution of...

IntelliJ IDEA Validate JSP File JAR Loading

The vulnerability of the Validate JSP File function in the IntelliJ IDEA integrated development environment is related to the transmission of critical information in open text. Exploiting this vulnerability allows a malicious actor to download arbitrary JAR files remotely...

Deserialization of untrusted data

An attacker can use SnakeYAML to deserialize java.net.URLClassLoader and make it load a JAR from a specified URL, and then deserialize javax.script.ScriptEngineManager to load code using that ClassLoader. This unbounded deserialization can likely lead to remote code execution. The code can be run...
