Overview
Affected versions of this package are vulnerable to Replay Attack through the getUserByOIDCToken() process in FacebookProvider.php. An attacker can impersonate a victim account by replaying a captured, valid Facebook OIDC id_token to userFromToken() without providing a matching session nonce. The affected code verifies the token signature, audience, and issuer but does not bind the token to the expected nonce value, so an unexpired token issued for the same Facebook App ID is accepted as authentic. This lets an unauthenticated attacker gain unauthorized access to the target user’s account and the application session created from that token.
