What we know

No known exploitation. CISA KEV, checked 23:19 UTC.
No public exploit code known. Exploit-DB, Metasploit, Nuclei, checked 23:18 UTC.
An attacker only needs network access to the target. No login needed. CVSS: network, no privileges.
It only works under certain conditions, which makes it harder to pull off. CVSS: high attack complexity.
Someone has to open, click or run something first. CVSS: user interaction required.

Description

Apache Wicket 10.10.0, 10.11.0 and 9.24.0 do not set the Content-Security-Policy headers on a page whose render request handler is wrapped in more than one IRequestHandlerDelegate. The framework unwraps only a single delegate level when deciding whether a request renders a page, so with a deeper chain, for example an application-provided delegating request mapper combined with CryptoMapper, the page is served without any CSP header even though CSP is enabled, and no error or warning is raised. The nonce-based protection Wicket applies to inline scripts and styles, together with any other CSP directives configured by the application, is thereby lost for those pages, exposing them to content injection the policy was meant to prevent. Applications on stock Wicket that do not wrap request handlers themselves are not affected. Versions before 10.10.0 and 9.24.0 handled nested delegates correctly. Users are recommended to upgrade to version 10.12.0 or 9.25.0, which fix the issue.
