Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-77602 exists.\n\nAffected packages and fixed versions:\n- openc3 (RubyGems): affected from 5.1.0; fixed in 7.3.0\n- openc3 (RubyGems): affected from 5.1.0; fixed in 7.3.0\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-2026-77602/ (Markdown: https://insights.sbomify.com/CVE-2026-77602/index.md)","id":"CVE-2026-77602","markdown":"https://insights.sbomify.com/CVE-2026-77602/index.md","name":"CVE-2026-77602","record":{"aliases":["GHSA-jjq7-m736-w977"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenC3 COSMOS","requires_auth":"low_privilege","summary":"Authenticated non-admin users can achieve remote code execution and privilege escalation by injecting malicious content into user-writable configuration overlays.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems.
