Script execution via nested command URI
Published Mar 4, 2025 · Updated Nov 3, 2025
Improper input validation in LibreOffice 24.8 before 24.8.5 and 25.2 before 25.2.1 allows attackers to execute scripts via a browser link. The vnd.libreoffice.command URI handler accepts an embedded inner URL and forwards arbitrary arguments to internal macros instead of rejecting the nested command. A browser must pass the crafted link to LibreOffice; successful processing runs an internal macro in the local user's application context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=24.8 << 24.8.5
- Affected versionversion=25.2 << 25.2.1
