Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2022-41968 and fix it if it is affected.\n\nWhat it is: CVE-2022-41968 is a low-severity denial of service vulnerability in Nextcloud Nextcloud Server, published on 1 Dec 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-41968 in the wild and no public exploit code.\n\nAffected product: Nextcloud Nextcloud Server. 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-2022-41968/ (Markdown: https://insights.sbomify.com/CVE-2022-41968/index.md)","id":"CVE-2022-41968","markdown":"https://insights.sbomify.com/CVE-2022-41968/index.md","name":"CVE-2022-41968","record":{"aliases":["GHSA-m92j-xxc8-hq3v"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Server","requires_auth":"low_privilege","summary":"An attacker can cause denial of service by sending excessive data to the database due to missing validation on calendar name lengths.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nextcloud_server","vendor":"nextcloud"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Nextcloud Server is an open source personal cloud server.
