Description

Joomla Extension - joomshaper.com - Authenticated Privileged SQL Injection in the Content Plugin of SP Page Builder (Free and Pro) 5.2.1 - 6.9.0 - plgContentSppagebuilder::onContentAfterSave() read jform[attribs][sppagebuilder_article_id] from the request and concatenated it directly into the WHERE view_id = ... clause of a query against #__sppagebuilder without quoting or type casting. Joomla's ARRAY input filter does not sanitise element values, as InputFilter::clean() returns (array) $source with the elements untouched, so the entire payload could be delivered in a single POST field. The affected block also executed before the com_content.article context test, so it ran on every onContentAfterSave event regardless of which component triggered the save. An attacker could perform time-based blind SQL injection to read arbitrary database contents, including the #__users and #__session tables.

Analysis

Technical impact

An authenticated Joomla user can exploit a SQL injection flaw in the SP Page Builder extension’s content plugin. The plugin reads the sppagebuilder_article_id field from the request and concatenates it directly into a WHERE clause without sanitization read arbitrary database tables, including the users and session tables, thereby compromising user credentials and session data.

Because the injection is time‑based and blind, an attacker does not need direct access to the database but can retrieve sensitive data through response timing. The attack can be carried out in a normal administrative or editorial context, making it a significant threat to sites running the affected plugin.
