CVE-2026-33213: Redash

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

Redash is a package for data visualization and sharing. From 5.0.2 to 26.3.0, the get_next_path() function in Redash's authentication module stripped the scheme and netloc from user-supplied next parameters but did not normalize multiple leading slashes, allowing a crafted login URL such as /login?next=////evil.com to redirect users to an external attacker-controlled site after authentication.

Affected products

• Redash Redash: from 5.0.2, before 26.03.1 (fixed in 26.03.1)
