{"cve":"CVE-2025-55202","nvd":{"published":"2025-08-29T16:15:36.863","modified":"2026-10-19T17:10:00.173","status":"Analyzed","description":"Opencast is a free, open-source platform to support the management of educational audio and video content. In version 18.0 and versions before 17.7, the protections against path traversal attacks in the UI config module are insufficient, still partially allowing for attacks in very specific cases. The path is checked without checking for the file separator. This could allow attackers access to files within another folder which starts with the same path. This issue has been fixed in versions 17.7 and 18.1. To mitigate this issue, check for folders that start with the same path as the ui-config folder.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U","score":2.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-23"],"references":["https://github.com/opencast/opencast/commit/e2cc65d6fbe052ebb71d9f6b583bb54b181af009","https://github.com/opencast/opencast/pull/6979","https://github.com/opencast/opencast/security/advisories/GHSA-hq8m-v68g-8cf8"],"products":["apereo:opencast"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-55202","score":0.00385,"percentile":0.32308,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-hq8m-v68g-8cf8","url":"https://osv.dev/vulnerability/GHSA-hq8m-v68g-8cf8","summary":"Opencast has a partial path traversal vulnerability in UI config","modified":"2025-08-29T21:35:15.719551Z","packages":[{"ecosystem":"Maven","name":"org.opencastproject:opencast-user-interface-configuration","purl":"pkg:maven/org.opencastproject/opencast-user-interface-configuration","ranges":["<17.7"],"fixed":["17.7"]},{"ecosystem":"Maven","name":"org.opencastproject:opencast-user-interface-configuration","purl":"pkg:maven/org.opencastproject/opencast-user-interface-configuration","ranges":[">=18.0 <18.1"],"fixed":["18.1"]}]}],"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).
