In NLnet Labs Unbound 1.6.2 up to and including 1.25.1, when Unbound is configured with the 'respip' module in front of the validator together with a 'response-ip' redirect rule or an RPZ file with an RPZ-IP trigger, the rewriting handler does not check the security status of the upstream answer and can instead rewrite a BOGUS A/AAAA answer to point to an operator's configured IP. If the validator finds an expired or otherwise invalid RRSIG on an answer whose A record falls within a 'response-ip'/RPZ configuration, the answer is still rewritten and given a hard coded security level of INSECURE. This results in the client receiving an INSECURE NOERROR reply rewritten by the operator's configured IP. A malicious actor can exploit the possible poisonous effect by spoofing a BOGUS A/AAAA answer that falls inside the operator's configured subnet rewrites. Such DNSSEC protected answers are then insecurely redirected to the operator's configured target.

CVE-2026-46415 is an improper access control vulnerability in the caddy-defender plugin for Caddy. Versions prior to 0.10.1 use the immediate peer IP address (RemoteAddr) instead of the resolved client IP when behind trusted proxies, allowing clients from blocked IP ranges to bypass IP-based blocking. This affects deployments using trusted proxies, CDNs, or load balancers. The issue is fixed in version 0.10.1 by using the resolved client IP when available. No complete workaround exists in affected versions except enforcing IP blocking at the proxy or edge layer. Deployments without intermediate proxies are not affected.
