CVE-2025-10642

Vulnerability

Analysis

CVE-2025-10642 describes a reflected cross-site scripting (XSS) vulnerability in the chat_forum project by wangchenyi1996. The flaw resides in the file /q.php, where the path argument is not properly sanitized before being reflected in the server's response [1]. This allows an attacker can craft a malicious URL containing JavaScript code in the path parameter, and when a victim visits that URL, the script executes in the context of the victim's browser session.

Exploitation

The attack is remotely exploitable and does not require authentication. The only prerequisite is that the victim clicks on a crafted link (e.g., sent via email, social media, or embedded in another page). Because the product operates on a rolling release basis, there are no fixed version numbers; the vulnerability exists in all commits up to 80bdb92f5b460d36cab36e530a2c618acef5afd2 [1]`.

Impact

Successful exploitation allows an attacker to execute arbitrary JavaScript in the victim's browser. This can lead to session hijacking, defacement, or theft of sensitive data displayed on the page. The CVSS v3 base score is 3.5 (Low), reflecting the need for user interaction and the limited scope of impact (confidentiality and integrity only).

Mitigation

As of the publication date (2025-09-18), no official patch has been released. Users are advised to apply input validation on the path parameter or upgrade to a commit after the vulnerable range if available. The project maintainer has not yet addressed this issue in the public repository.
