      "value": "Giskard is an open-source testing framework for AI models. In versions prior to 1.0.2b1, the RegexMatching check passes a user-supplied regular expression pattern directly to Python's re.search() without any timeout or complexity guard. A crafted regex pattern can trigger catastrophic backtracking, causing the process to hang indefinitely. Exploitation requires write access to a check definition and subsequent execution of the test suite. This issue has been fixed in giskard-checks version 1.0.2b1."

      "value": "Giskard es un framework de pruebas de código abierto para modelos de IA. En versiones anteriores a la 1.0.2b1, la comprobación RegexMatching pasa un patrón de expresión regular proporcionado por el usuario directamente a re.search() de Python sin ningún tiempo de espera o protección contra la complejidad. Un patrón de regex manipulado puede desencadenar un retroceso catastrófico, haciendo que el proceso se cuelgue indefinidamente. La explotación requiere acceso de escritura a una definición de comprobación y la ejecución posterior de la suite de pruebas. Este problema se ha solucionado en la versión 1.0.2b1 de giskard-checks."
