  • Sep 17, 2026The OpenFeature Operator allows users to expose feature flags to applications.CVE-2026-54495 · Other software · open-feature · reported by GitHubMedium 4.3

    The OpenFeature Operator allows users to expose feature flags to applications. In version 0.9.2 and earlier, a tenant who can create a controller-owned workload can use the openfeature.dev/featureflagsource annotation with NAMESPACE/NAME syntax to reference a FeatureFlagSource or InProcessConfiguration in another namespace. On multi-tenant clusters that use namespaces as trust boundaries, the cluster-scoped operator reads that resource and materializes spec.envVars literal values, spec.httpSyncBearerToken, sync URIs, and supporting ConfigMaps into the tenant's workload. Single-tenant clusters are not impacted, secretKeyRef and configMapKeyRef values remain namespace-local, and creating a FeatureFlagSource is not required.

  • Apr 14, 2023The OpenFeature Operator allows users to expose feature flags to applications.CVE-2023-29018 · Other software · open-feature · reported by GitHubHigh 8

    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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
