CVE-2026-76838

CVE-2026-76838 is a high-severity vulnerability in Hi.Events that allows for server-side request forgery (SSRF) via unvalidated webhook redirects. The vulnerability exists because the Hi.Events application does not revalidate a webhook destination at dispatch time, allowing an attacker to cause the server to make unintended requests. This issue was addressed in version 1.11.1-beta.
