CVE-2026-81564: Joomla Extension - joomshaper.com - Missing Directory Confinement in Media Rename Allowing Arbitrary File Rename in SP Page Builder (Free and Pro) 4.0.0 - 6.9.0
Joomla Extension - joomshaper.com - Missing Directory Confinement in Media Rename Allowing Arbitrary File Rename in SP Page Builder (Free and Pro) 4.0.0 - 6.9.0 - The media rename task applied neither of the directory boundary checks used by the folder operations in the same controller, and its validation guard required only that either a media record exist for the supplied identifier or that the supplied path be present in #spmedia, rather than both. The identifier and the path were consequently never checked against one another, so any valid media identifier could be paired with an unrelated filesystem path, and the STR input filter left traversal sequences intact. An attacker could rename files elsewhere in the installation, including renaming configuration.php to take the site offline.

Event History
Frequently Asked Questions
Does the supplied file path need to belong to the media record identified in the request?
No. The rename validation did not verify that the supplied identifier and path referred to one another. A valid media identifier could be combined with an unrelated filesystem path.
What makes paths outside the intended media area reachable?
The media rename task did not apply the directory-boundary checks used by folder operations in the same controller. Its STR input filtering also left traversal sequences intact.
Can this affect availability rather than only media files?
Yes. The issue can rename files elsewhere in the installation. The described impact includes renaming configuration.php, which can take the site offline.
