A flaw was found in npm-prismjs. An attacker can craft a string that will take a very long time to highlight when used to work with un-trusted text resulting in ReDoS. This can affect the system availability. There is no known risk of privilege escalation on data compromise.
Mitigation
As a workaround, do not use ASCIIDoc or ERB to highlight untrusted text.
