Caddyserver

Caddyserver's vulnerability profile centers on Caddy, a single widely deployed web server and reverse proxy, whose positioning in the request path and TLS termination role makes its flaws consequential across diverse deployment contexts. Vulnerabilities affecting the vendor skew strongly toward critical-severity outcomes, have a moderate tendency toward confirmed in-the-wild exploitation, and frequently acquire public exploit code; the recurring weakness classes—including sensitive-information disclosure, improper authentication, case-sensitivity handling errors, input-validation gaps, and open-redirect flaws—reflect the authentication, TLS, and HTTP-parsing logic inherent to a modern web-server implementation. Defenders should prioritize Caddy updates and inventory deployments serving internet-facing services; live severity, exploitation, and exposure counts are shown alongside this summary.
