Open Redirect in Kiwi TCMS account confirmation endpoint

IdentifiersCVE-2026-54724CWE-601

CVE-2026-54724 is an open redirect vulnerability in Kiwi TCMS affecting the account confirmation endpoint. The issue is caused by insufficient validation of a user-controllable next parameter, which allows an attacker to supply an arbitrary external URL that is used as the post-confirmation redirect target. As a result, a victim following a legitimate-looking Kiwi TCMS account confirmation link can be redirected off-site to attacker-controlled infrastructure. Based on the provided content, affected versions include all versions through 12.4.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an unauthenticated attacker to abuse trusted Kiwi TCMS URLs for phishing and social-engineering operations. Victims may be redirected to attacker-controlled domains for credential harvesting, malware delivery, or other follow-on attacks. The vulnerability can also help bypass link-reputation checks or email security controls by embedding the malicious destination behind a legitimate Kiwi TCMS domain.

Mitigation

If you can’t patch tonight, do this now.

Until a fixed release is applied, restrict the account confirmation endpoint so that any next parameter is limited to relative local paths or an explicit allowlist of trusted same-origin destinations. Where code changes are not immediately possible, consider filtering or blocking requests containing external redirect targets, monitoring for suspicious confirmation links, and warning users not to trust post-confirmation redirects to external domains.

Remediation

Patch, then assume compromise.

Upgrade Kiwi TCMS to a version newer than 12.4 once a vendor-fixed release is available. If a patched version has been released by the vendor, deploy that release across all affected instances and verify that the account confirmation flow rejects or safely normalizes untrusted external redirect targets supplied via the next parameter.
