CVE-2024-48913: Hono

Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.

Hono, a web framework, prior to version 4.6.5 is vulnerable to bypass of cross-site request forgery (CSRF) middleware by a request without Content-Type header. Although the CSRF middleware verifies the Content-Type Header, Hono always considers a request without a Content-Type header to be safe. This can allow an attacker to bypass CSRF protection implemented with Hono CSRF middleware. Version 4.6.5 fixes this issue.

Affected products

• Hono Hono: before 4.6.5 (fixed in 4.6.5)
