What is CVE-2026-107718?
CVE-2026-107718 is a medium-severity vulnerability in adonisjs http-server, published on 8 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. Prior to 8.2.3 and 9.3.0, AdonisJS HTTP Server inserts route parameter values into URLs without encodeURIComponent in the shared createURL() helper used by Router.makeUrl() and Response.redirect().toRoute(). If an application places attacker-controlled data in a dynamic first path segment and uses the generated route URL as a redirect destination, a value beginning with a slash can produce a scheme-relative external URL. Wildcard parameters are affected by the same missing encoding, while APIs intentionally accepting complete redirect URLs are not affected. An attacker can redirect users from a trusted application to an attacker-controlled site, facilitating phishing or abuse of authentication and OAuth flows. This issue is fixed in versions 8.2.3 and 9.3.0.
