AI-analyzed exploit summary This repository describes an information disclosure vulnerability in Planka v2.0.0-rc.4 and below, where missing X-Frame-Options and CSP frame-ancestors headers allow the application to be embedded in malicious iframes, enabling UI redressing attacks.

Description

PLANKA 2.0.0 lacks X-Frame-Options and CSP frame-ancestors headers, allowing the application to be embedded within malicious iframes. While this does not lead to unintended modification of projects or tasks, it exposes users to Phishing attacks. Attackers can frame the legitimate Planka application on a malicious site to establish false trust (UI Redressing), potentially tricking users into entering sensitive information or credentials into overlaid fake forms. NOTE: this is disputed by the Supplier because "PLANKA uses SameSite=Strict cookies, preventing authentication in cross-origin contexts. No session can be established. No credential interception or unauthorized actions are possible. Browser Same-Origin Policy prevents the parent page from accessing iframe content. Clickjacking is not applicable on the login page. Any credential capture would require attacker-controlled input and user interaction equivalent to phishing. The security outcome depends entirely on the user's trust in the parent page. An attacker can achieve the same effect with a fully fake login page. Embedding the legitimate page adds no risk, as browsers do not show URL, certificate, or padlock indicators in cross-origin iframes."
