CVE-2023-50572Public exploit

Process crash via unbounded multiline output splitting

Published Dec 29, 2023 · Updated Aug 2, 2024

Resource exhaustion in JLine GroovyEngine 3.24.1 allows local users to crash the hosting Java process via crafted multiline input. DefaultPrinter.highlightAndPrint splits the entire rendered string into an unbounded array of lines before highlighting and printing it, allowing crafted Groovy content to exhaust heap memory. Execution requires a hosting application to pass attacker-controlled content to GroovyEngine and process its output; the resulting OOM can terminate that Java process.
