Severity

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

The Kuadrant operator's internal WebAssembly shim has a flaw that allows crafted HTTPRoute match values to bypass gateway policy overrides. A user with access to create or modify an HTTPRoute can provide a malicious path, header, or query match value. This affects the Red Hat Connectivity Link and Red Hat OpenShift AI products.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Until a fixed release is available, restrict HTTPRoute creation and modification for routes attached to the shared Gateway, and review or remove routes with match values that trigger the predicate injection. Where possible, enforce authentication and rate limiting at the backend as additional controls. An admission policy could reject confirmed exploit patterns, but validate it against legitimate routes; Gateway API match values can contain special characters. These measures reduce exposure but do not fix the shim. The backend and admission-policy measures are compensating controls; their effectiveness depends on the deployment and the specific route behavior

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher description

A flaw was found in the internal WebAssembly (WASM) shim used by the Kuadrant operator. When generating the CEL predicate that determines whether Gateway-level authentication and rate limiting should run, the shim does not correctly escape values from HTTPRoute match fields. A user who can create or modify an HTTPRoute attached to a shared Gateway can provide a crafted path, header, or query match value that causes the predicate to skip those checks. The request is still forwarded to the route’s backend.
