High CVSS 8.3

CVE-2026-49226

NVD analysis in progress

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.4, Vvveb backend post operations allow a low-privileged Author to access posts owned by another Author. The admin/controller/content/posts.php controller permits filter[admin_id] to replace the server-selected admin_id restriction and accepts a caller-controlled post_id for duplicate and delete actions, while admin/sql/sqlite/post.sql does not consistently enforce post.admin_id. An attacker can view post metadata, discover post identifiers, duplicate posts, or delete posts and related content, exposing private drafts and causing content pollution, data loss, or business disruption. This issue is fixed in version 1.0.8.4.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read some data, modify or destroy data and take the service offline.
Weakness
Changing an identifier in the request grants access to another user’s data.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.
