Mô tả CVE
liboauth2 is vulnerable to Server-Side Request Forgery in oauth2_jose_jwks_aws_alb_resolve() function. The AWS ALB verifier reads both signer and kid from the unverified JWT
header. If signer matches the configured ARN, kid is appended to
alb_base_url without URL encoding or path sanitization, and the HTTP GET
is issued before signature verification. This allows an attacker to force
the server to send a GET request to an attacker-chosen internal path.
This issue was fixed in version 2.3.0
