CVE-2026-33503 Â (opens in a new tab)How to fix?
Upgrade github.com/ory/kratos/courier to version 26.2.0 or higher.
Overview
Affected versions of this package are vulnerable to SQL Injection in the listCourierMessages() function in handler.go. An attacker in possession of the configured secrets.pagination with access to the ListCourierMessages API can execute arbitrary SQL queries by forging a pagination token. Applications on which secrets.pagination configuration is not set are also vulnerable because they fall back to a default pagination secret.
Note: In the interim, if the package cannot be upgraded immediately, the effects of this vulnerability can be mitigated by generating a cryptographically secure pagination secret and not revealing it to untrusted parties.
