Description:
- CVE-2026-9256: heap buffer overflow in ngx_http_script_regex_start_code() when a rewrite replacement contains overlapping captures with the redirect parameter or argument string; the per-capture length accumulation is refactored to also account for escape-uri expansion per capture region, preventing under-allocation of the rewrite output buffer
