Hybrid Manager - LTS: Missing Authentication for Critical Functionality

Published Updated By the CyberSecBulletin desk

CVE-2025-14038 is a high-severity missing authentication for critical functionality vulnerability in Hybrid Manager - LTS from EnterpriseDB, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.3.3 as the first without the flaw, so updating Hybrid Manager - LTS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.23% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Hybrid Manager - LTS to 1.3.3 or a later version.
  2. Update Hybrid Manager - Innovation to 2025.12 or a later version.
  3. Update Hybrid Manager to 1.3.3 or 2025.12.0, whichever matches your release line, or a later version.
  4. Read the advisory on enterprisedb.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

EDB Hybrid Manager contains a flaw that allows an unauthenticated attacker to directly access certain gRPC endpoints. This could allow an attacker to read potentially sensitive data or possibly cause a denial-of-service by writing malformed data to certain gRPC endpoints. This flaw has been remediated in EDB Hybrid Manager 1.3.3, and customers should consider upgrading to 1.3.3 as soon as possible. The flaw is due to a misconfiguration in the Istio Gateway, which manages authentication and authorization for the affected endpoints. The security policy relies on an explicit definition of required permissions in the Istio Gateway configuration, and the affected endpoints were not defined in the configuration. This allowed requests to bypass both authentication and authorization within a Hybrid Manager service. All versions of Hybrid Manager - LTS should be upgraded to 1.3.3, and all versions of Hybrid Manager - Innovation should be upgraded to 2025.12.

The underlying weakness: Missing Authentication for Critical Functionality

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

How developers prevent this class of flaw

  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
  • When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
