CVE-2026-33503
Ory Kratos has a SQL injection via forged pagination tokens
In short
Ory Kratos allows attackers to inject malicious SQL code through fake pagination tokens in its admin API. If the system uses a default or known encryption secret, anyone can create harmful tokens to manipulate the database.
Technical detail
SQL injection vulnerability in ListCourierMessages Admin API via crafted pagination tokens encrypted with a known or default secret. An attacker with knowledge of the pagination encryption secret can construct malicious tokens that bypass input validation, leading to unauthorized database queries and potential data exfiltration or manipulation. Affects versions prior to 26.2.0.
Summary generated and translated by AI from the official description.
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.
