Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55108 exists.\n\nAffected packages and fixed versions:\n- github.com/oam-dev/kubevela (Go): affected all versions; fixed in 1.9.14, 1.10.9, 1.11.0-alpha.4\n- github.com/oam-dev/kubevela (Go): affected all versions; fixed in 1.9.14\n- github.com/oam-dev/kubevela (Go): affected all versions; fixed in 1.9.14\n- github.com/oam-dev/kubevela (Go): affected from 1.10.0-alpha.1; fixed in 1.10.9\n- github.com/oam-dev/kubevela (Go): affected from 1.10.0-alpha.1; fixed in 1.10.9\n- github.com/oam-dev/kubevela (Go): affected from 1.11.0-alpha.1; fixed in 1.11.0-alpha.4\n- github.com/oam-dev/kubevela (Go): affected from 1.11.0-alpha.1; fixed in 1.11.0-alpha.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55108/ (Markdown: https://insights.sbomify.com/CVE-2026-55108/index.md)","id":"CVE-2026-55108","markdown":"https://insights.sbomify.com/CVE-2026-55108/index.md","name":"CVE-2026-55108","record":{"aliases":["GHSA-fmgp-q6jx-gg3x","GO-2026-6312"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"KubeVela application delivery","requires_auth":"low_privilege","summary":"An attacker with ComponentDefinition permissions can cause a denial of service by triggering an unbounded file read via symlinks, exhausting memory and crashing the controller.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"KubeVela is an open source application delivery platform. Prior to 1.9.14, from 1.10.0-alpha.1 until 1.10.9, and from 1.11.0-alpha.1 until 1.11.0-alpha.4, the Terraform remote configuration loader in pkg/controller/utils/capability.go, GetTerraformConfigurationFromRemote, clones a repository supplied through a core.oam.dev/v1beta1 ComponentDefinition and follows repository-controlled variables.tf or main.tf symlinks. A user with permission to create or update ComponentDefinition objects can point variables.tf to /dev/zero through terraform.path, after which os.Stat and os.ReadFile follow the link and read an unbounded stream before ParseTerraformVariables or HCL parsing can reject the content. The read can exhaust memory, OOM-kill the cluster-wide vela-core controller, cause repeated Pod restarts, and pressure node memory when no effective container limit is configured.
