TL;DR Summary

An 18-year-old heap buffer overflow in NGINX's rewrite_module (CVE-2026-42945) can cause denial of service and, under specific rewrite configurations, unauthenticated remote code execution. Patches are available in NGINX Open Source 1.31.0 and 1.30.1 and related F5 products; real-world exploitability is debated, but the DoS risk makes patching or applying mitigations urgent, especially where ASLR is disabled to enable RCE in PoC tests.
