CVE-2019-16409 secureassets and versionedfiles modules can expose versions of protected files
- Severity:
- Medium (?)
- Identifier:
- CVE-2019-16409
- Versions Affected:
- ^4.0
- Versions Fixed:
- 4.3.5, 4.4.4
- Release Date:
- 2019-09-24
Users who migrated from a 3.x site that used the versionedfiles module will have its _versions folders left as artefacts in their public filesystems, leaving all the unpublished versions of old files publicly accessible under a guessable URL. This module was superseded by the file versioning functionality provided by the core 4.x recipe, meaning these _versions folders have no ongoing functional utility and should be deleted or blocked from web requests.
Base CVSS Score: 5.9
CWP CVSS Score: 5.9
