An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41255 exists.\n\nAffected packages and fixed versions:\n- ckan (PyPI): affected from 2.10.0; fixed in 2.10.10, 2.11.5\n- ckan (PyPI): affected from 2.10.0; fixed in 2.10.10\n- ckan (PyPI): affected from 2.10.0; fixed in 2.10.10\n- ckan (PyPI): affected from 2.11.0; fixed in 2.11.5\n- ckan (PyPI): affected from 2.11.0; fixed in 2.11.5\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-2026-41255/ (Markdown: https://insights.sbomify.com/CVE-2026-41255/index.md)","id":"CVE-2026-41255","markdown":"https://insights.sbomify.com/CVE-2026-41255/index.md","name":"CVE-2026-41255","record":{"aliases":["GHSA-mcvf-jxcw-vj73","PYSEC-2026-2418"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CKAN data portal","requires_auth":"none","summary":"An unauthenticated request can permanently disable CSRF protection for a server worker, allowing attackers to bypass CSRF defenses in CKAN data portals.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ckan","vendor":"okfn"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.10 and 2.11.5, Access to the views via tokens or unauthenticated requests marked the endpoint as not requiring CSRF protection. The marking was a member variable in flask-wtf.csrf.CSRFProtect(), which was stored as a module level variable in the flask_app middleware. This API was never intended for request level changes, it is primarily a decorator for static configuration. An unauthenticated request could hit a protected endpoint, exempting it from CSRF protection for the life of the particular server process. (e.g. one worker of uwsgi).
