A flaw was found in mistune. This algorithmic complexity vulnerability allows an unauthenticated remote attacker to cause a Denial of Service (DoS) by submitting specially crafted Markdown input containing long sequences of unmatched bracket characters. When parsing this malformed input, the inline link parser consumes excessive CPU resources, rendering processing workers unresponsive.
