CVE-2026-107914 Details

Description

Backdrop CMS 1.34 before 1.34.5 and 1.35 before 1.35.1 doesn't sufficiently protect configuration exports when delivering a compressed archive. This vulnerability is mitigated by the fact that an export must have been previously requested by someone with the "Synchronize, import, and export configuration" permission. NOTE: CVE-2026-107914 refers to the vulnerability in which config.admin.inc does not ensure that a file_unmanaged_delete operation occurs. Therefore, many archives could persist: config.tar.gz, config_0.tar.gz, config_1.tar.gz, etc. There is a separate config.module issue that could allow remote access by an anonymous user, but only for the one filename config.tar.gz.
