CVE-2026-5630 describes a cross-site scripting (XSS) vulnerability discovered in gpt-researcher, specifically impacting versions 3.4.0 through 3.4.3. This flaw resides within the Report API component, allowing an attacker to inject malicious scripts. The vulnerability is remotely exploitable and a public proof-of-concept exists, highlighting the potential for immediate exploitation. The project maintainers have not yet responded to the reported issue.
Successful exploitation of CVE-2026-5630 allows an attacker to inject arbitrary JavaScript code into the gpt-researcher application. This could lead to a variety of malicious outcomes, including session hijacking, defacement of the application's user interface, and redirection to phishing sites. The attacker could potentially steal sensitive user data, such as API keys or authentication tokens, if the application handles such information. Given the remote nature of the vulnerability and the availability of a public exploit, the risk of exploitation is significant. The impact is amplified if the gpt-researcher application is exposed to the public internet or integrated with other systems.
CVE-2026-5630 was publicly disclosed on 2026-04-06. A proof-of-concept exploit is publicly available, indicating a relatively high probability of exploitation. The vulnerability has been added to the NVD database. The lack of response from the project maintainers increases the risk of continued exploitation.

The primary mitigation for CVE-2026-5630 is to upgrade to a patched version of gpt-researcher. As of this writing, no patched version has been released. Until a patch is available, consider implementing input validation and sanitization on the Report API endpoint to prevent the injection of malicious scripts. Web application firewalls (WAFs) configured to detect and block XSS payloads can provide an additional layer of defense. Monitor application logs for suspicious activity, such as unusual JavaScript execution patterns. Since no patch is available, careful review of the backend/server/app.py file for potential vulnerabilities is recommended.
