This post is intended as a “technical two-pager” to summarize a security vulnerability called Regex-based Denial of Service (AKA Regex DoS, ReDoS). There are a variety of write-ups about ReDoS, but I’m not aware of a good one-stop-shop with a higher-level treatment of all aspects of the subject. I have included links at the end to more detailed treatments.
