CVE-2024-21677Network attack vector

Unauthenticated file compromise through plugin path traversal

Published Mar 19, 2024 · Updated Mar 13, 2025

Path traversal in Atlassian Confluence Data Center allows remote attackers to compromise files through user-assisted requests. The flaw resides in the bundled Confluence Cloud Migration Assistant plugin, but Atlassian has not disclosed the affected handler, input field, or filesystem operation. Successful exploitation requires no authentication but does require user interaction and compromises file confidentiality, integrity, and service availability.
