An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-59148 exists.\n\nAffected packages and fixed versions:\n- @mockoon/cli (npm): affected all versions; fixed in 9.7.0\n- @mockoon/cli (npm): affected all versions; fixed in 9.7.0\n- @mockoon/commons-server (npm): affected all versions; fixed in 9.7.0\n- @mockoon/commons-server (npm): affected all versions; fixed in 9.7.0\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-2026-59148/ (Markdown: https://insights.sbomify.com/CVE-2026-59148/index.md)","id":"CVE-2026-59148","markdown":"https://insights.sbomify.com/CVE-2026-59148/index.md","name":"CVE-2026-59148","record":{"aliases":["GHSA-rqx4-3f6q-3x2v"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Mockoon API mocking tool","requires_auth":"none","summary":"Unauthenticated access to Mockoon's admin API allows attackers to steal secrets and modify mock server state due to missing authentication and permissive CORS settings.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"},{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-352","name":"Cross-Site Request Forgery"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Mockoon provides way to design and run mock APIs. Prior to 9.7.0, Mockoon's admin API in commons-server/src/libs/server/admin-api.ts is mounted on the same Express listener as user-defined mock routes, enabled by default in shipped runtimes, serves Access-Control-Allow-Origin: * with write methods allowed, and has no authentication. Any unauthenticated caller who can reach the mock server port can read MOCKOON_* environment variables, write arbitrary process environment variables through /mockoon-admin/env-vars, rewrite mock route bodies, statuses, and headers through PUT /mockoon-admin/environment, read transaction logs and SSE streams, and purge state.
