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). This vulnerability is fixed in 2.10.10 and 2.11.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-352"],"references":["https://github.com/Shirshaw64p/security-advisories/tree/main/CVE-2026-41255","https://github.com/ckan/ckan/security/advisories/GHSA-mcvf-jxcw-vj73","https://github.com/ckan/ckan/security/advisories/GHSA-mcvf-jxcw-vj73"],"products":["okfn:ckan"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-41255","score":0.00124,"percentile":0.02109,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mcvf-jxcw-vj73","url":"https://osv.dev/vulnerability/GHSA-mcvf-jxcw-vj73","summary":"CKAN has CSRF exemption primed by anonymous requests","modified":"2026-07-13T16:43:10.423197768Z","packages":[{"ecosystem":"PyPI","name":"ckan","purl":"pkg:pypi/ckan","ranges":[">=2.10.0 <2.10.10"],"fixed":["2.10.10"]},{"ecosystem":"PyPI","name":"ckan","purl":"pkg:pypi/ckan","ranges":[">=2.11.0 <2.11.5"],"fixed":["2.11.5"]}]},{"id":"PYSEC-2026-2418","url":"https://osv.dev/vulnerability/PYSEC-2026-2418","summary":"CKAN has CSRF exemption primed by anonymous requests","modified":"2026-07-13T16:31:42.479091391Z","packages":[{"ecosystem":"PyPI","name":"ckan","purl":"pkg:pypi/ckan","ranges":[">=2.10.0 <2.10.10",">=2.11.0 <2.11.5"],"fixed":["2.10.10","2.11.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
