AI-suggested

Red Hat has released fixed versions of Red Hat Quay 3: 3.9.28, 3.10.28, 3.12.24, 3.14.10, 3.15.9, 3.16.7, 3.17.7, and 3.18.3. Users should update to these versions to fully remediate the vulnerability. Red Hat has already patched the Quay.io service. There is no complete workaround other than updating. If immediate update is not possible, restrict permissions to create namespaces containing underscores, rotate robot tokens for namespaces that collide with underscore-containing ones, and monitor registry activity for anomalous pulls or pushes. These interim steps reduce exposure but do not fix the underlying flaw.

Description

CVE-2026-110697 is a critical SQL injection vulnerability in Red Hat Quay 3's robot account listing function. It arises because user-controlled namespace names are used to construct SQL LIKE patterns without escaping wildcard characters, allowing an attacker to create a namespace with an underscore that matches other tenants' namespaces. This flaw enables cross-tenant credential theft by listing and retrieving robot account tokens from other tenants, which can then be used to perform unauthorized image operations. The vulnerability affects multi-tenant Quay deployments and can compromise container supply chains in OpenShift environments. Fixed versions have been released by Red Hat.
