Detailsinfo

A vulnerability, which was classified as problematic, was found in PLANKA 2.0.0. This affects an unknown function. The manipulation with an unknown input leads to a cross-domain policy vulnerability. CWE is classifying the issue as CWE-942. The product uses a cross-domain policy file that includes domains that should not be trusted. This is going to have an impact on integrity. The summary by CVE is:

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."

This vulnerability is uniquely identified as CVE-2025-65922 since 11/18/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/06/2026).

The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
