Last modified

CVE-2025-6623 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. The carbon console accepts user-supplied XML input without sufficiently encoding potentially executable content, allowing for the injection of malicious scripts. Successful exploitation allows a remote attacker to execute arbitrary JavaScript in the context of a victim's browser, leading to actions such as redirecting the user to a malicious website or modifying the web page's user interface. Session hijacking is not possible as sensitive session cookies are protected by the httpOnly flag.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
