This flaw, classified as CWE\u2011434, permits an attacker to submit a file with a dangerous content type. While the CVE does not confirm execution of code, an attacker could potentially deliver a malicious payload that may be processed by the application, creating risks for confidentiality, integrity, or availability. The vulnerability is limited to the form upload interface and does not affect other components directly.", "risk_and_exploitability": "The CVSS score of 5.5 reflects moderate severity, indicating that the flaw can impact non\u2011privileged users who can access the upload interface. EPSS data is not available, and the vulnerability is not listed in CISA\u2019s KEV catalog. The likely attack path is a simple network request from a user with manager access; an attacker could upload a dangerous file, potentially leading to further compromise if the file is processed or executed by the application."}}}}, "created": "2026-03-25T21:46:42.629900+00:00", "updated": "2026-03-25T21:46:42.629957+00:00", "vendors": []}
