Because no validation is performed, an attacker who is authenticated can configure that URL to point to internal services, cloud metadata endpoints, or localhost resources. By forcing the application to contact those targets, the attacker can gather internal network information, extract credentials from cloud metadata services, or interact with database or admin interfaces. This SSRF flaw allows the attacker to potentially read or manipulate data inside the environment, affecting confidentiality and integrity of the internal infrastructure. The flaw is represented by CWE\u2011918.", "risk_and_exploitability": "The CVSS score of 5.8 indicates a moderate severity. The EPSS score is not available, so exploitation probability is unknown. It is not listed in the CISA KEV catalog.

The most straightforward attack vector is an authenticated user setting a webhook URL that points to an internal service or cloud metadata endpoint."}}}}, "created": "2026-04-20T17:30:12.650052+00:00", "updated": "2026-04-20T17:30:12.650062+00:00", "vendors": []}
