GHSA-2W6W-674Q-4C4Q Handlebars.js has JavaScript Injection via AST Type Confusion

Summary Handlebars.compile accepts a pre-parsed AST object in addition to a template string. The value field of a NumberLiteral AST node is emitted directly into the generated JavaScript without quoting or sanitization. An attacker who can supply a crafted AST to compile can therefore inject and...

Detecting Data Poisoning in Code Generation LLMs Via Black-Box, Vulnerability-Oriented Scanning

Code generation large language models LLMs are increasingly integrated into modern software development workflows. Recent work has shown that these models are vulnerable to backdoor and poisoning attacks that induce the generation of insecure code, yet effective defenses remain limited. Existing...

Name of the Vulnerable Software and Affected Versions re2c versions up to 4.4 Description A flaw exists in re2c that can lead to a null pointer dereference. The issue is located in the check and merge special rules function within the src/parse/ast.cc file. This manipulation can be exploited...

Detecting PowerShell-Based Fileless Cryptojacking Attacks Using Machine Learning

With the emergence of remote code execution RCE vulnerabilities in ubiquitous libraries and advanced social engineering techniques, threat actors have started conducting widespread fileless cryptojacking attacks. These attacks have become effective with stealthy techniques based on PowerShell-bas...

Regular Expression Denial of Service (ReDoS)

Overview minimatch is a minimal matching utility. Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS in the AST class, caused by catastrophic backtracking when an input string contains many characters in a row, followed by an unmatched character. Detail...

CVE-2026-25533

Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.10.1, the existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the error objects does not cover the peculiar...

CVE-2022-23628

OPA is an open source, general-purpose policy engine. Under certain conditions, pretty-printing an abstract syntax tree AST that contains synthetic nodes could change the logic of some statements by reordering array literals. Example of policies impacted are those that parse and compare web paths...

CodeQL zero to hero part 5: Debugging queries

When you're first getting started with CodeQL, you may find yourself in a situation where a query doesn't return the results you expect. Debugging these queries can be tricky, because CodeQL is a Prolog-like language with an evaluation model that's quite different from mainstream languages like...

VerilogLAVD: LLM-Aided Rule Generation for Vulnerability Detection in Verilog

Timely detection of hardware vulnerabilities during the early design stage is critical for reducing remediation costs. Existing early detection techniques often require specialized security expertise, limiting their usability. Recent efforts have explored the use of large language models LLMs for...

Breaking Obfuscation: Cluster-Aware Graph with LLM-Aided Recovery for Malicious JavaScript Detection

With the rapid expansion of web-based applications and cloud services, malicious JavaScript code continues to pose significant threats to user privacy, system integrity, and enterprise security. But, detecting such threats remains challenging due to sophisticated code obfuscation techniques and...

github.com/expr-lang/expr: Memory Exhaustion in Expr Parser with Unrestricted Input

A flaw was found in Expr. This vulnerability allows excessive memory usage and potential out-of-memory OOM crashes via unbounded input strings, where a malicious or inadvertent large expression can cause the parser to construct an extremely large Abstract Syntax Tree AST, consuming excessive memo...

H2O 资源管理错误漏洞

H2O is an in-memory platform for distributed, scalable machine learning open-sourced by H2O.ai. A resource management error vulnerability exists in H2O version 3.46.0.1, which stems from the runtool command exposing classes in the water.tools package via the ast parser, which could lead to a deni...

Memory Exhaustion in Expr Parser with Unrestricted Input

Impact If the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree AST node for each part of the expression. In scenarios where input size isn’t limited, a malicious or inadvertent extremely large expression c...
