Security Bulletin: 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, affects watsonx.data

Summary In scenarios where input size isn't limited, a malicious or inadvertent extremely large expression can consume excessive memory as the parser builds a huge AST. This can ultimately lead toexcessive memory usage and an Out-Of-Memory OOM crash of the process. This issue is relatively uncomm...

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...
