CVE-2026-53683
Description
reset_password.html parses query string parameters and uses the 'url' parameter as a redirection target (window.location = url) after password reset, optionally delayed by a 'delay' parameter. No validation or allowlisting is performed on url, enabling an attacker to redirect users to an arbitrary external site after completion of the password-reset workflow.
Statement
Rated Moderate because exploitation requires a victim to follow a crafted link, and the direct technical impact is limited to a client-side redirect with no data disclosure or modification. The practical risk is phishing/social-engineering enablement rather than a direct technical compromise.
Mitigation
Eliminate arbitrary URL redirects. If a post-reset return URL is required, allowlist same-origin paths only, or validate against a strict allowlist of trusted hosts and the HTTPS scheme. Prefer server-generated, signed return tokens instead of raw URLs, and ensure the UI uses safe navigation helpers that reject dangerous schemes and external origins.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
