An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-66256 in the wild and no public exploit code.\n\nAffected product: Apache Shindig Common. 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-2026-66256/ (Markdown: https://insights.sbomify.com/CVE-2026-66256/index.md)","id":"CVE-2026-66256","markdown":"https://insights.sbomify.com/CVE-2026-66256/index.md","name":"CVE-2026-66256","record":{"aliases":["GHSA-pwr8-4vxm-3h37"],"analysis":{"component_type":"server_software","fix_type":"end_of_life","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Shindig","requires_auth":"high_privilege","summary":"Attackers with REST API access can trigger arbitrary code execution via unsafe deserialization in the retired Apache Shindig server.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"shindig","vendor":"apache"}],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"** UNSUPPORTED WHEN ASSIGNED ** Deserialization of Untrusted Data vulnerability in Apache Shindig.\n\nThis issue affects Apache Shindig: all versions.\n\nUsers with access to the Shindig REST API can send specially-crafted requests to trigger arbitrary code execution on the server.\n\nAs this project is retired, we do not plan to release a version that fixes this issue.
