By manipulating the batch argument sent to the file, an attacker can inject arbitrary JavaScript that is reflected back to the victim\u2019s browser. This reflected cross\u2011site scripting would allow a malicious actor to execute code within the context of any user who views the affected page, potentially stealing session cookies, credentials, or injecting malicious content. The weakness is based on improper input handling and rendering, making the application vulnerable to client\u2011side attacks.", "risk_and_exploitability": "The CVSS score for this issue is 5.3, indicating moderate severity. EPSS information is not available, and the vulnerability is not listed in CISA\u2019s KEV catalog, so it does not receive additional alerting.
