AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Flatboard Pro prior to 3.2.2 allows stored XSS via footer_text and announcement parameters in config.php due to insufficient input validation.

Vulnerability

CVE-2025-40723 is a stored cross-site scripting (XSS) vulnerability affecting Flatboard Pro versions prior to 3.2.2. The flaw exists in the config.php file, where the footer_text and announcement parameters are not properly validated or sanitized, allowing an attacker to inject arbitrary HTML and JavaScript code [1].

Exploitation

To exploit this vulnerability, an attacker must have access to the configuration page (config.php), typically requiring administrator-level privileges. Once the malicious payload is saved, it is stored and executed whenever other users view pages that include the injected content, such as the footer or announcement area [1].

Impact

Successful exploitation enables an attacker to execute arbitrary JavaScript in the context of a victim's browser. This can lead to session hijacking, defacement, theft of sensitive information, or further attacks against other users of the forum [1].

Mitigation

The vulnerability has been addressed by the Flatboard Pro team in version 3.2.2. Users are strongly advised to upgrade to the latest version to mitigate the risk [1].
