CVE-2026-55620: Regex Fixpoint Loop Dos
Repeatedly applying regular expression substitution in a fixpoint loop until the string stops changing can cause quadratic O(N^2) running time on nested inputs, leading to CPU exhaustion Denial of Service (DoS). Replace the loop with a single-pass or stack-based parser.
