CVE-2024-4148Public exploitNetwork attack vector

Service crash via inefficient evaluator filter regex

Published Jun 1, 2024 · Updated Jan 30, 2025

Regular expression denial of service in Lunary before 1.3.4 allows remote attackers to crash the application with a crafted request. The evaluator creation endpoint accepts filters as a string and passes them to deserializeLogic, where crafted regular-expression content consumes excessive processing time. No authentication or user interaction is required, and exploitation interrupts the Lunary service without affecting data confidentiality or integrity.
