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-2026-88763 in the wild and no public exploit code.\n\nAffected product: Red Hat Service Interconnect 2 for RHEL 8. 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-2026-88763/ (Markdown: https://insights.sbomify.com/CVE-2026-88763/index.md)","id":"CVE-2026-88763","markdown":"https://insights.sbomify.com/CVE-2026-88763/index.md","name":"CVE-2026-88763","record":{"aliases":["GHSA-j54j-r8q7-v2hq","RHSA-2026:82316"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Red Hat Service Interconnect","requires_auth":"none","summary":"An attacker can crash the skupper-router by sending a crafted AMQP message, causing a denial of service for interconnected services.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"A flaw was found in the skupper-router component of Red Hat Service Interconnect, which is used to provide secure communication between distributed services.
