An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-47725 exists.\n\nAffected packages and fixed versions:\n- github.com/juev/nebula-mesh (Go): affected all versions; fixed in 0.3.3\n- github.com/juev/nebula-mesh (Go): affected all versions; fixed in 0.3.3\n- github.com/juev/nebula-mesh (Go): affected all versions; fixed in 0.3.3\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-2026-47725/ (Markdown: https://insights.sbomify.com/CVE-2026-47725/index.md)","id":"CVE-2026-47725","markdown":"https://insights.sbomify.com/CVE-2026-47725/index.md","name":"CVE-2026-47725","record":{"aliases":["GHSA-273q-qgh5-wrj6","GO-2026-5049"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Nebula mesh control plane","requires_auth":"none","summary":"Attackers can force authenticated users to perform unwanted actions on the nebula-mesh web interface due to missing CSRF tokens on mutating endpoints.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network.
