{"id":"CVE-2025-6623","kind":"vulnerability","aliases":["CVE-2025-6623"],"related":[],"title":"Carbon console: XML input enables script injection into victims' browsers","description":"The carbon console accepts user-supplied XML input without sufficiently encoding potentially executable content, allowing for the injection of malicious scripts.\n\nSuccessful 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.","summary":"The carbon console accepts user-supplied XML without encoding executable content, so injected scripts run in a victim's browser. An attacker can redirect users to malicious sites or alter the page interface, but session cookies are httpOnly and cannot be stolen this way.","severity":"medium","cvss":4.3,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["carbon-console","other"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-19T17:16:59+00:00","first_seen_at":"2026-10-23T21:57:18+00:00","triaged_at":"2026-10-25T04:39:35+00:00","updated_at":"2026-10-25T04:39:35+00:00","category":"other","confidence":0.5,"triage":{"at":"2026-10-25T04:39:35Z","model":"claude-haiku-5-5","output":{"fix":"unknown","reach":"internet","title":"Carbon console: XML input enables script injection into victims' browsers","impact":"medium","summary":"The carbon console accepts user-supplied XML without encoding executable content, so injected scripts run in a victim's browser.
