CVE-2026-81564: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in joomshaper.com SP Page Builder (Free and Pro) extension for Joomla
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.
AI Analysis
Technical Summary
The SP Page Builder extension for Joomla (versions 4.0.0 to 6.9.0) contains a path traversal vulnerability in its media rename task. The vulnerability arises because the rename operation does not enforce directory boundary checks and only requires either a media record or a path to be present, not both. This allows an attacker to pair any valid media identifier with an unrelated filesystem path, bypassing validation and enabling arbitrary file renaming. The STR input filter does not sanitize traversal sequences, facilitating this attack vector.
Potential Impact
An attacker with high privileges can rename arbitrary files within the Joomla installation, including critical configuration files such as configuration.php. This can disrupt site functionality, potentially taking the site offline or causing other operational impacts. The CVSS 4.0 base score is 7.0 (high severity), reflecting network attack vector, low attack complexity, no user interaction, and high impact on integrity and availability.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory from joomshaper.com for current remediation guidance. Until a fix is available, restrict access to the media rename functionality to trusted administrators only and monitor for suspicious activity related to file renaming.
