What is CVE-2026-82476?

Memos versions up to 0.30.0 are vulnerable to Server-Side Request Forgery (SSRF) due to the omission of the 100.64.0.0/10 carrier-grade NAT address range from its security measures. This oversight allows unauthenticated attackers to exploit the application, bypassing IP validation, and making requests to internal network resources. Consequently, attackers can access sensitive data from cloud metadata services and retrieve confidential information, such as page titles and descriptions.

Affected Version(s)

memos 0 <= 0.30.0
