## 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.

Weakness: CWE-601 (URL Redirection to Untrusted Site)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
