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-2026-65959 exists.\n\nAffected packages and fixed versions:\n- vitess.io/vitess (Go): affected all versions; fixed in 0.23.6, 0.24.3\n- vitess.io/vitess (Go): affected all versions up to 0.23.6; no fix listed\n- vitess.io/vitess (Go): affected all versions up to 0.23.6; no fix listed\n- vitess.io/vitess (Go): affected from 0.24.0-rc1 up to 0.24.2; no fix listed\n- vitess.io/vitess (Go): affected from 0.24.0-rc1 up to 0.24.2; no fix listed\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-2026-65959/ (Markdown: https://insights.sbomify.com/CVE-2026-65959/index.md)","id":"CVE-2026-65959","markdown":"https://insights.sbomify.com/CVE-2026-65959/index.md","name":"CVE-2026-65959","record":{"aliases":["AZL-96770","GHSA-mhc4-g3wh-cw7m","GO-2026-6356"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Vitess database clustering","requires_auth":"none","summary":"Remote attackers can access the vttablet debug endpoint to view sensitive VReplication SQL data and bypass security policies due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Vitess is a database clustering system for horizontal scaling of MySQL.
