CVE-2026-105605 Details
Description
Joomla Extension - dj-extensions.com - IDOR vulnerability allowing cross-account ad access in DJ-Classifieds < 3.11.3 - A “duplicate my ad” convenience feature on the new-ad form (site/models/additem.php) loaded an existing advert by its raw numeric ID with no check that the ad belonged to the requesting user, and no check of whether it was published, blocked, or still a pending draft. Any logged-in user, regardless of role, could request the new-ad form with another ad’s ID and have that ad’s full content, including the seller’s phone number, address, email, and price, rendered into the response, even for ads that had never been published. Advert IDs are small sequential integers.
An Insecure Direct Object Reference (IDOR) vulnerability has been identified in the Joomla DJ-Classifieds extension, versions prior to 3.11.3. This vulnerability allows logged-in users to access and duplicate ads from other users' accounts without permission. The issue arises because the 'duplicate my ad' feature on the new-ad form retrieves an existing advert using its numeric ID, without verifying if the ad belongs to the user making the request or checking the ad's publication status. As a result, users can access sensitive information such as the seller's phone number, address, email, and price, even for unpublished ads.
