Ory Hydra has a SQL injection via forged pagination tokens

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

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.

## Description Following Admin APIs in Ory Hydra are vulnerable to SQL injection due to flaws in its pagination implementation: - listOAuth2Clients - listOAuth2ConsentSessions - listTrustedOAuth2JwtGrantIssuers 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. ## Preconditions This issue can be exploited when the following conditions are met: - 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 - 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 ## Impact An attacker can execute arbitrary SQL queries through forged pagination tokens. ## Mitigation As a first line of defense, immediately configure a custom value for `secrets.pagination` by generating a cryptographically secure random secret, for example: ``` openssl rand -base64 32 ``` Next, upgrade **Hydra** to the fixed version **as soon as possible**.
