CVE-2026-19078 (GCVE-0-2026-19078)

Vulnerability from cvelistv5 – Published: 2026-08-11 15:34 – Updated: 2026-08-11 15:56

Title

Ose-oauth-server: oauth-server: open redirect vulnerability enables phishing via unvalidated parameter.

Summary

A flaw was found in the oauth-server component. This open redirect vulnerability occurs when the 'then' parameter in the grant approval handler is not properly validated. A remote attacker can craft a malicious URL that, when approved or denied by an authenticated user, redirects them to an attacker-controlled website. This could enable phishing attacks, potentially tricking users into revealing sensitive information.

Severity

4.3 (Medium)

  "details": "A flaw was found in the oauth-server component. This open redirect vulnerability occurs when the \u0027then\u0027 parameter in the grant approval handler is not properly validated. A remote attacker can craft a malicious URL that, when approved or denied by an authenticated user, redirects them to an attacker-controlled website. This could enable phishing attacks, potentially tricking users into revealing sensitive information.",
