At a glance
CVE-2023-2996 is a medium-severity Improper Input Validation vulnerability in the Jetpack WordPress plugin, affecting versions 2.0 – 12.1 · 102 branches. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 10.0.1; sites on affected versions should update now. Disclosed May 2023, reported by Miguel Neto.
Vulnerability Overview
The Jetpack plugin for WordPress is vulnerable to arbitrary file manipulation in versions up to, and including, 12.1. This is due to insufficient validation on data being supplied to the media API endpoint. This makes it possible for authenticated attackers, with author-level permissions and above, to modify arbitrary files in the WordPress Installation.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity.
CWE-20: Improper Input Validation
Reaching this weakness in Jetpack 2.0 – 12.1 · 102 branches takes an account at Author level or above. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.
The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Jetpack the fix is 10.0.1: builds 2.0 – 12.1 · 102 branches are affected, anything from 10.0.1 onward is not.
Remediation
Update to one of the following versions, or a newer patched version: 10.0.1, 10.1.1, 10.2.2, 10.3.1, 10.4.1, 10.5.2, 10.6.2, 10.7.1, 10.8.1, 10.9.2, 11.0.1, 11.1.3, 11.2.1, 11.3.3, 11.4.1, 11.5.2, 11.6.1, 11.7.2, 11.8.5, 11.9.2, 12.0.1, 12.1.1, 2.0.9, 2.1.7, 2.2.10, 2.3.10, 2.4.7, 2.5.5, 2.6.6, 2.7.5, 2.8.5, 2.9.6, 3.0.6, 3.1.5, 3.2.5, 3.3.6, 3.4.6, 3.5.6, 3.6.4, 3.7.5, 3.8.5, 3.9.9, 4.0.6, 4.1.3, 4.2.4, 4.3.4, 4.4.4, 4.5.2, 4.6.2, 4.7.3, 4.8.4, 4.9.2, 5.0.2, 5.1.3, 5.2.4, 5.3.3, 5.4.3, 5.5.4, 5.6.4, 5.7.4, 5.8.3, 5.9.3, 6.0.3, 6.1.4, 6.2.4, 6.3.6, 6.4.5, 6.5.3, 6.6.4, 6.7.3, 6.8.4, 6.9.3, 7.0.4, 7.1.4, 7.2.4, 7.3.4, 7.4.4, 7.5.6, 7.6.3, 7.7.5, 7.8.3, 7.9.3, 8.0.2, 8.1.3, 8.2.5, 8.3.2, 8.4.4, 8.5.2, 8.6.3, 8.7.3, 8.8.4, 8.9.3, 9.0.4, 9.1.2, 9.2.3, 9.3.4, 9.4.3, 9.5.4, 9.6.3, 9.7.2, 9.8.2, 9.9.2
How does WordSec protect against this?
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Jetpack 10.0.1 closes this, and updating the plugin is the step that ends it.
