An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18461 in the wild and no public exploit code.\n\nAffected product: RTI Connext Professional. 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-2026-18461/ (Markdown: https://insights.sbomify.com/CVE-2026-18461/index.md)","id":"CVE-2026-18461","markdown":"https://insights.sbomify.com/CVE-2026-18461/index.md","name":"CVE-2026-18461","record":{"aliases":["GHSA-hxc8-pv67-w823"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RTI Connext Professional","requires_auth":"none","summary":"Format string injection in RTI Connext Professional core libraries allows attackers to execute code or cause denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"RTI","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"Use of Externally-Controlled Format String vulnerability in RTI Connext Professional (Core Libraries) allows Format String Injection.
