It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-42283 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/loft-sh/devspace (Go): affected all versions; no fix listed\n- github.com/loft-sh/devspace (Go): affected from 6.3.20; fixed in 6.3.21\n- github.com/loft-sh/devspace (Go): affected from 6.3.20; fixed in 6.3.21\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-2026-42283/ (Markdown: https://insights.sbomify.com/CVE-2026-42283/index.md)","id":"CVE-2026-42283","markdown":"https://insights.sbomify.com/CVE-2026-42283/index.md","name":"CVE-2026-42283","record":{"aliases":["GHSA-hqwm-7x7x-8379","GO-2026-5433"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DevSpace UI Server","requires_auth":"none","summary":"A malicious website can access DevSpace UI server endpoints via cross-origin WebSocket connections, potentially exposing sensitive data.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"devspace","vendor":"devspace"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"DevSpace is a client-only developer tool for cloud-native development with Kubernetes. Prior to 6.3.21, DevSpace's UI server WebSocket accepts connections from all origins by default, and therefore several endpoints are exposed via this WebSocket. When a developer runs the DevSpace UI and at the same time uses a browser to access the internet, a malicious website they visit can use their browser to establish a cross-origin WebSocket connection to ws://127.0.0.1:8090.
