{"id":"CVE-2025-30343","details":"A directory traversal issue was discovered in OpenSlides before 4.2.5. Files can be uploaded to OpenSlides meetings and organized in folders. The interface allows users to download a ZIP archive that contains all files in a folder and its subfolders. If an attacker specifies the title of a file or folder as a relative or absolute path (e.g., ../../../etc/passwd), the ZIP archive generated for download converts that title into a path. Depending on the extraction tool used by the user, this might overwrite files locally outside of the chosen directory.","modified":"2026-08-12T03:51:33.751344201Z","published":"2025-03-21T00:00:00Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"fixed":"4.2.5"}],"source":"AFFECTED_FIELD"},{"source":"DESCRIPTION","extracted_events":[{"fixed":"4.2.5"}]}],"cna_assigner":"mitre","cwe_ids":["CWE-24"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30343.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30343.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30343"},{"type":"ADVISORY","url":"https://www.x41-dsec.de/lab/advisories/x41-2025-001-OpenSlides"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openslides/openslides","events":[{"introduced":"0"},{"fixed":"89d3f5b68366d630219b4d4c4e43c747e7815ec1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.2.5"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:openslides:openslides:*:*:*:*:*:*:*:*"}}],"versions":["4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.22","4.1.21","4.1.20","4.1.19","4.1.18","4.1.17","4.1.16","4.1.15","4.1.14","4.1.13","4.1.12","4.1.11","4.1.7","4.1.0","4.0.0","1.3","1.2","1.1","1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-30343.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N"}]}
