    CVE-2026-31866 (GCVE-0-2026-31866)

    Vulnerability from nvd – Published: 2026-03-11 17:49 – Updated: 2026-03-12 13:50
    VLAI
    Title
    Allocation of Resources Without Limits or Throttling in flagd
    Summary
    flagd is a feature flag daemon with a Unix philosophy. Prior to 0.14.2, flagd exposes OFREP (/ofrep/v1/evaluate/...) and gRPC (evaluation.v1, evaluation.v2) endpoints for feature flag evaluation. These endpoints are designed to be publicly accessible by client applications. The evaluation context included in request payloads is read into memory without any size restriction. An attacker can send a single HTTP request with an arbitrarily large body, causing flagd to allocate a corresponding amount of memory. This leads to immediate memory exhaustion and process termination (e.g., OOMKill in Kubernetes environments). flagd does not natively enforce authentication on its evaluation endpoints. While operators may deploy flagd behind an authenticating reverse proxy or similar infrastructure, the endpoints themselves impose no access control by default. This vulnerability is fixed in 0.14.2.

    CVE-2023-29018 (GCVE-0-2023-29018)

    Vulnerability from nvd – Published: 2023-04-14 18:47 – Updated: 2025-02-06 18:42
    VLAI
    Title
    OpenFeature Operator vulnerable to Cluster-level Privilege Escalation
    Summary
    The OpenFeature Operator allows users to expose feature flags to applications. Assuming the pre-existence of a vulnerability that allows for arbitrary code execution, an attacker could leverage the lax permissions configured on `open-feature-operator-controller-manager` to escalate the privileges of any SA in the cluster. The increased privileges could be used to modify cluster state, leading to DoS, or read sensitive data, including secrets. Version 0.2.32 mitigates this issue by restricting the resources the `open-feature-operator-controller-manager` can modify.

    flagd is a feature flag daemon with a Unix philosophy. Prior to 0.14.2, flagd exposes OFREP (/ofrep/v1/evaluate/...) and gRPC (evaluation.v1, evaluation.v2) endpoints for feature flag evaluation. These endpoints are designed to be publicly accessible by client applications. The evaluation context included in request payloads is read into memory without any size restriction. An attacker can send a single HTTP request with an arbitrarily large body, causing flagd to allocate a corresponding amount of memory. This leads to immediate memory exhaustion and process termination (e.g., OOMKill in Kubernetes environments). flagd does not natively enforce authentication on its evaluation endpoints.

Prior to 0.14.2, flagd exposes OFREP (/ofrep/v1/evaluate/...) and gRPC (evaluation.v1, evaluation.v2) endpoints for feature flag evaluation. These endpoints are designed to be publicly accessible by client applications. The evaluation context included in request payloads is read into memory without any size restriction. An attacker can send a single HTTP request with an arbitrarily large body, causing flagd to allocate a corresponding amount of memory. This leads to immediate memory exhaustion and process termination (e.g., OOMKill in Kubernetes environments). flagd does not natively enforce authentication on its evaluation endpoints. While operators may deploy flagd behind an authenticating reverse proxy or similar infrastructure, the endpoints themselves impose no access control by default. This vulnerability is fixed in 0.14.2."

    CVE-2023-29018 (GCVE-0-2023-29018)

    Title
    OpenFeature Operator vulnerable to Cluster-level Privilege Escalation
    Summary
    The OpenFeature Operator allows users to expose feature flags to applications. Assuming the pre-existence of a vulnerability that allows for arbitrary code execution, an attacker could leverage the lax permissions configured on `open-feature-operator-controller-manager` to escalate the privileges of any SA in the cluster. The increased privileges could be used to modify cluster state, leading to DoS, or read sensitive data, including secrets. Version 0.2.32 mitigates this issue by restricting the resources the `open-feature-operator-controller-manager` can modify.
