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-2026-59726 exists.\n\nAffected product: ruvnet ruflo. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-59726/ (Markdown: https://insights.sbomify.com/CVE-2026-59726/index.md)","id":"CVE-2026-59726","markdown":"https://insights.sbomify.com/CVE-2026-59726/index.md","name":"CVE-2026-59726","record":{"aliases":["GHSA-c4hm-4h84-2cf3"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruflo MCP bridge","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands and read API keys via exposed MCP bridge endpoints in Ruflo's default Docker deployment.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Ruflo is an agent meta-harness for Claude Code and Codex.
