{"cve":"CVE-2020-5228","nvd":{"published":"2020-01-30T20:15:10.310","modified":"2026-06-17T03:21:04.077","status":"Modified","description":"Opencast before 8.1 and 7.6 allows unauthorized public access to all media and metadata by default via OAI-PMH. OAI-PMH is part of the default workflow and is activated by default, requiring active user intervention of users to protect media. This leads to users unknowingly handing out public access to events without their knowledge. The problem has been addressed in Opencast 7.6 and 8.1 where the OAI-PMH endpoint is configured to require users with `ROLE_ADMIN` by default. In addition to this, Opencast 9 removes the OAI-PMH publication from the default workflow, making the publication a conscious decision users have to make by updating their workflows.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-862"],"references":["https://github.com/opencast/opencast/blob/1fb812c7810c78f09f29a7f455ff920417924307/etc/security/mh_default_org.xml#L271-L276","https://github.com/opencast/opencast/security/advisories/GHSA-6f54-3qr9-pjgj","https://github.com/opencast/opencast/blob/1fb812c7810c78f09f29a7f455ff920417924307/etc/security/mh_default_org.xml#L271-L276","https://github.com/opencast/opencast/security/advisories/GHSA-6f54-3qr9-pjgj"],"products":["apereo:opencast"],"source":"nvd","synced_at":"2026-10-19T21:01:01.339895972+00:00"},"epss":{"cve":"CVE-2020-5228","score":0.00977,"percentile":0.62161,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-6f54-3qr9-pjgj","url":"https://osv.dev/vulnerability/GHSA-6f54-3qr9-pjgj","summary":"Unauthenticated Access Via OAI-PMH","modified":"2026-09-10T03:49:25.227365468Z","packages":[{"ecosystem":"Maven","name":"org.opencastproject:opencast-oaipmh-api","purl":"pkg:maven/org.opencastproject/opencast-oaipmh-api","ranges":["<7.6"],"fixed":["7.6"]},{"ecosystem":"Maven","name":"org.opencastproject:opencast-oaipmh-api","purl":"pkg:maven/org.opencastproject/opencast-oaipmh-api","ranges":[">=8.0 <8.1"],"fixed":["8.1"]}]}],"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).
