CVE-2026-81564 Details
Description
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.
A vulnerability exists in the Joomla extension SP Page Builder, both Free and Pro versions, within the directory confinement of the media rename task. This issue allows for arbitrary file renaming, as the task fails to apply proper directory boundary checks. The validation only requires that either a media record exists for the provided identifier or that the path is present in the SP Media table, rather than ensuring both criteria are met. As a result, any valid media identifier can be matched with an unrelated filesystem path, leaving traversal sequences intact. An attacker could exploit this to rename files elsewhere in the installation, potentially causing disruption by, for example, renaming the configuration.php file to take the site offline.
