It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-11389 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-2026-11389/ (Markdown: https://insights.sbomify.com/CVE-2026-11389/index.md)","id":"CVE-2026-11389","markdown":"https://insights.sbomify.com/CVE-2026-11389/index.md","name":"CVE-2026-11389","record":{"aliases":["GHSA-v63h-ppxr-x489"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"RTI Connext Professional","requires_auth":"low_privilege","summary":"An out-of-bounds read and type confusion vulnerability in RTI Connext Professional core libraries allows attackers to overread buffers, potentially leading to information disclosure or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"RTI","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"},{"id":"CWE-685","name":"Function Call With Incorrect Number of Arguments"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds Read, Function Call With Incorrect Number of Arguments, Access of Resource Using Incompatible Type ('Type Confusion') vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers.
