It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-26455 and fix it if it is affected.\n\nWhat it is: CVE-2023-26455 is a medium-severity missing authorization vulnerability in Open-Xchange Open-Xchange Appsuite, published on 2 Nov 2023. 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-2023-26455 in the wild and no public exploit code.\n\nAffected product: Open-Xchange Open-Xchange Appsuite. 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-2023-26455/ (Markdown: https://insights.sbomify.com/CVE-2023-26455/index.md)","id":"CVE-2023-26455","markdown":"https://insights.sbomify.com/CVE-2023-26455/index.md","name":"CVE-2023-26455","record":{"aliases":["GHSA-9wv2-mrrp-v8g7"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OX App Suite","requires_auth":"high_privilege","summary":"Attackers with local or adjacent network access can modify calendar items via an unauthenticated RMI service in OX App Suite.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[{"product":"open-xchange_appsuite","vendor":"open-xchange"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"RMI was not requiring authentication when calling ChronosRMIService:setEventOrganizer.
