CVE-2026-33504

Ory Hydra has a SQL injection via forged pagination tokens

CVSS 7.2 HIGHEPSS 0.3%CWE-89
In short

Ory Hydra's pagination system has a flaw that allows attackers who know a secret key to create fake pagination tokens containing malicious SQL commands. If an attacker can access the admin APIs that use pagination, they can execute unauthorized database queries.

Technical detail

SQL injection vulnerability in Ory Hydra's listOAuth2Clients, listOAuth2ConsentSessions, and listTrustedOAuth2JwtGrantIssuers Admin APIs due to improper token validation in pagination implementation. An attacker with knowledge of secrets.pagination or secrets.system can forge encrypted pagination tokens to inject arbitrary SQL. Attack vector requires network access to affected admin endpoints and knowledge of the encryption secret; impact includes unauthorized database query execution and potential data compromise.

Summary generated and translated by AI from the official description.
Ory Hydra is an OAuth 2.0 Server and OpenID Connect Provider. Prior to version 26.2.0, the listOAuth2Clients, listOAuth2ConsentSessions, and listTrustedOAuth2JwtGrantIssuers Admin APIs in Ory Hydra are vulnerable to SQL injection due to flaws in its pagination implementation. Pagination tokens are encrypted using the secret configured in `secrets.pagination`. If this value is not set, Hydra falls back to using `secrets.system`. An attacker who knows this secret can craft their own tokens, including malicious tokens that lead to SQL injection. This issue can be exploited when one or more admin APIs listed above are directly or indirectly accessible to the attacker; the attacker can pass a raw pagination token to the affected API; and the configuration value `secrets.pagination` is set and known to the attacker, or `secrets.pagination` is not set and `secrets.system` is known to the attacker. An attacker can execute arbitrary SQL queries through forged pagination tokens. As a first line of defense, immediately configure a custom value for `secrets.pagination` by generating a cryptographically secure random secret. Next, upgrade Hydra to the fixed version, 26.2.0 as soon as possible.
