The vulnerability CVE-2025-30603 affects DEJAN CopyLink through version 1.1 and involves a CSRF flaw that enables stored XSS attacks. This means an attacker could trick an authenticated user into submitting a request that stores malicious script code, which then executes in the context of the victim's browser. The CVSS vector indicates the attack can be performed remotely over the network without privileges but requires user interaction. The impact includes partial confidentiality, integrity, and availability loss.

Successful exploitation could lead to stored XSS attacks, allowing an attacker to execute arbitrary scripts in the context of the victim's browser. This can result in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The CVSS score of 7.1 reflects a high severity but not critical.

No official patch or remediation guidance is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, users should consider implementing CSRF protections such as anti-CSRF tokens and input sanitization to mitigate stored XSS risks where possible.
