## What is CVE-2026-54724?

CVE-2026-54724 is a medium-severity vulnerability in kiwitcms Kiwi, published on 15 Sep 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

Kiwi TCMS is an open source test management system. Prior to 16.1, the account confirmation endpoint accepted an unvalidated next parameter, allowing an unauthenticated attacker to create a URL on a trusted Kiwi TCMS hostname that redirects a victim to an arbitrary external domain. The trusted origin can support credential-harvesting pages, bypass email security filters and link-reputation checks that allowlist the organization's domain, or deliver malware through a convincing account-confirmation lure. This issue is fixed in version 16.1.

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.
