CVE-2025-67618 describes a Reflected Cross-Site Scripting (XSS) vulnerability discovered in ArtstudioWorks Brookside. This vulnerability allows an attacker to inject malicious scripts into web pages viewed by other users, potentially leading to account compromise and data theft. The vulnerability impacts versions of Brookside from n/a up to and including 1.4. A patch is expected to be released by the vendor.
The primary impact of this Reflected XSS vulnerability lies in the attacker's ability to execute arbitrary JavaScript code within the context of a victim's browser session. This can be leveraged to steal sensitive information such as cookies, session tokens, and personally identifiable information (PII). An attacker could also redirect users to malicious websites, deface the Brookside application, or even gain control of the user's account. The scope of the attack is limited to users who interact with the vulnerable web page, but the potential for widespread impact exists if the application is widely used.
CVE-2025-67618 was publicly disclosed on 2026-03-19. The vulnerability is currently rated as HIGH severity (CVSS 7.1). No public proof-of-concept (POC) code has been released at the time of writing, but the relatively straightforward nature of Reflected XSS vulnerabilities suggests that a POC is likely to emerge. It is not currently listed on the CISA KEV catalog.

The immediate mitigation for CVE-2025-67618 is to upgrade Brookside to a patched version as soon as it becomes available. Until a patch is released, consider implementing input validation and output encoding on all user-supplied data to prevent the injection of malicious scripts. Web Application Firewalls (WAFs) can be configured to filter out potentially malicious requests containing XSS payloads. Regularly review and update Brookside's security configuration to minimize the attack surface. After upgrading, verify the fix by attempting to inject a simple XSS payload into a vulnerable input field and confirming that the script is not executed.
