| Doc Text: |
A flaw was found in marked, a markdown parser and compiler. An unauthenticated attacker can exploit this Denial of Service (DoS) vulnerability by providing a specific 3-byte input sequence (a tab, a vertical tab, and a newline). This input triggers an infinite recursion loop during parsing, leading to unbounded memory allocation and causing the host Node.js application to crash due to Memory Exhaustion (OOM).
