When a victim later loads the affected pages, the injected script runs in the victim\u2019s browser, potentially allowing session hijacking, data theft, or further client\u2011side attacks. The impact is primarily client\u2011side compromise, leading to possible theft of sensitive information or malicious interactions governed by the privileges of the logged\u2011in user.", "risk_and_exploitability": "The CVSS base score of 5.1 indicates moderate severity. The EPSS score below 1% suggests that exploitation is currently unlikely, and the vulnerability is not present in CISA\u2019s Known Exploited Vulnerabilities catalog. The likely attack vector requires the attacker to first authenticate to AgentFlow, after which they can inject the persistent script. Once injected, the script will execute on every page load for any user viewing that content, providing the attacker with repeat access to client\u2011side capabilities."}}}}, "created": "2026-02-10T11:34:26.157227+00:00", "updated": "2026-04-17T21:00:12.708112+00:00", "vendors": ["flowring", "flowring$PRODUCT$agentflow"]}
