{"id":"CVE-2025-45055","details":"Silverpeas 6.4.2 contains a stored cross-site scripting (XSS) vulnerability in the event management module. An authenticated user can upload a malicious SVG file as an event attachment, which, when viewed by an administrator, executes embedded JavaScript in the admin's session. This allows attackers to escalate privileges by creating a new administrator account. The vulnerability arises from insufficient sanitization of SVG files and weak CSRF protections.","modified":"2026-08-12T03:51:35.980905576Z","published":"2025-06-09T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/45xxx/CVE-2025-45055.json"},"references":[{"type":"WEB","url":"https://medium.com/@mingihongkim/privilege-escalation-via-svg-injection-in-silverpeas-6-4-2-b5ab1d5b6955"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/45xxx/CVE-2025-45055.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-45055"},{"type":"FIX","url":"https://github.com/Silverpeas/Silverpeas-Core/pull/1394"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/silverpeas/silverpeas-core","events":[{"introduced":"a4af07530d880b59a73e393a22c9d572afd09f09"},{"last_affected":"a4af07530d880b59a73e393a22c9d572afd09f09"}],"database_specific":{"cpe":"cpe:2.3:a:silverpeas:silverpeas:6.4.2:*:*:*:*:*:*:*","extracted_events":[{"introduced":"6.4.2"},{"last_affected":"6.4.2"}],"source":"CPE_STRING"}}],"versions":["6.4.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-45055.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"}]}
