The uploadfile parameter is not properly validated, allowing an attacker to supply arbitrary values that cause the application server to issue HTTP requests to any target URL.

EPSS data is not available, but the public availability of exploit code suggests that the flaw is likely to be used by threat actors.

Based on typical SSRF behavior, an attacker might be able to retrieve data from internal services if the server\u2019s outbound policy does not restrict access, or otherwise direct traffic to arbitrary destinations. The vulnerability is not listed in the CISA KEV catalog, yet its remote nature and public exploit code warrant prompt remediation."}}}}, "created": "2026-04-19T15:15:15.539476+00:00", "updated": "2026-04-19T15:15:15.656960+00:00", "vendors": ["phpems", "phpems$PRODUCT$phpems"]}
