## What is CVE-2026-81564?

CVE-2026-81564 is a high-severity path traversal vulnerability in joomshaper.com SP Page Builder (Free and Pro) extension for Joomla, published on 14 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official 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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
