How to Fix CVE-2026-33504

To remediate this vulnerability, upgrade all affected Github.com/ory/hydra dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/ory/hydra fixed: Latest secure release 
Upgrade github.com/ory/hydra to Latest secure release
github.com/ory/hydra/v2 fixed: 2.3.1-0.20260320110106-0b84568fffcc 
Upgrade github.com/ory/hydra/v2 to 2.3.1-0.20260320110106-0b84568fffcc
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/ory/hydra

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-33504, inspect your project dependencies for Github.com/ory/hydra:

inspect dependencies for github.com/ory/hydra

Analyze the terminal output to locate any version of Github.com/ory/hydra in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.1-0.20260320110106-0b84568fffcc), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where 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. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Github.com/ory/hydra, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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**.
