This vulnerability affects an unknown part of the component ListCourierMessages Admin API. The manipulation with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes: Ory Kratos is an identity, user management and authentication system for cloud services. Prior to version 26.2.0, the ListCourierMessages Admin API in Ory Kratos is vulnerable to SQL injection due to flaws in its pagination implementation. Pagination tokens are encrypted using the secret configured in `secrets.pagination`. An attacker who knows this secret can craft their own tokens, including malicious tokens that lead to SQL injection. If this configuration value is not set, Kratos falls back to a default pagination encryption secret. Because this default value is publicly known, attackers can generate valid and malicious pagination tokens manually for installations where this secret is not set. As a first line of defense, immediately configure a custom value for `secrets.pagination` by generating a cryptographically secure random secret. Next, upgrade Kratos** to a fixed version, 26.2.0 or later, as soon as possible. The advisory is shared for download at github.com. This vulnerability was named CVE-2026-33503 since 03/20/2026. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1505. Upgrading to version 26.2.0 eliminates this vulnerability.
