CVE-2026-33504
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOry 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOry Hydra prior to v26.2.0 contains SQL injection flaws in the pagination implementation of three Admin APIs (listOAuth2Clients, listOAuth2ConsentSessions, listTrustedOAuth2JwtGrantIssuers). Pagination tokens are encrypted with secrets.pagination (or secrets.system as fallback); an attacker with knowledge of this secret can forge malicious tokens to inject arbitrary SQL.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Ory Hydra versionRun `hydra version` or inspect the container image/tag to determine the installed versionAffected if The version is prior to v26.2.0 (e.g., 26.1.0, 26.0.0, older) or cannot be determined as 26.2.0+
-
Verify Admin API is exposedConfirm that the Hydra Admin API is accessible (typically on port 4445 or via HYDRA_ADMIN_URL configuration). The vulnerable endpoints are: /admin/clients, /admin/oauth2/consent/sessions, /admin/trusted OAuth2/jwt-grant/issuersAffected if The Admin API is publicly or externally accessible without strict access controls
-
Inspect secrets.pagination configurationCheck the Hydra configuration file (e.g., config.yaml) or environment variables for the `secrets.pagination` setting. Look for whether it is set to a cryptographically secure random value or if the fallback `secrets.system` is being usedAffected if secrets.pagination is not set, is set to a weak/predictable value, or secrets.system is being used as the pagination secret fallback
You are affected if Hydra version is below 26.2.0 AND the Admin API is accessible AND the pagination secret (secrets.pagination) is not properly configured to a secure random value.

dbcve · scoped26.2.0
Immediately set a cryptographically secure random value for secrets.pagination and upgrade to Hydra 26.2.0 or later to patch the SQL injection vulnerability.
26.2.0
- As an immediate first line of defense, configure a custom value for `secrets.pagination` in your Hydra configuration by generating a cryptographically secure random secret.
- Upgrade Hydra to version 26.2.0 or later.
