An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-50248 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ckan (PyPI): affected from 2.0; fixed in 2.9.10, 2.10.3\n- ckan (PyPI): affected from 2.0; fixed in 2.9.10\n- ckan (PyPI): affected from 2.0; fixed in 2.9.10\n- ckan (PyPI): affected from 2.10.0; fixed in 2.10.3\n- ckan (PyPI): affected from 2.10.0; fixed in 2.10.3\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-2023-50248/ (Markdown: https://insights.sbomify.com/CVE-2023-50248/index.md)","id":"CVE-2023-50248","markdown":"https://insights.sbomify.com/CVE-2023-50248/index.md","name":"CVE-2023-50248","record":{"aliases":["GHSA-7fgc-89cx-w8j5","PYSEC-2026-1249"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CKAN data portal","requires_auth":"high_privilege","summary":"An authenticated attacker with dataset creation permissions can cause a server out-of-memory denial of service by submitting a specially crafted field to the dataset form.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ckan","vendor":"okfn"}],"cvss":{"score":4.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"CKAN is an open-source data management system for powering data hubs and data portals.
