DescriptionCVE.org

Unauthenticated Broken Authentication in Flutterwave WooCommerce <= 3.3.0 versions.

AnalysisAI

Broken authentication in the Flutterwave WooCommerce WordPress plugin (versions <= 3.3.0) allows unauthenticated remote attackers to bypass authentication controls via an alternate path or channel (CWE-288), resulting in limited integrity and availability impact. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no credentials, no user interaction, and no special network position, making it trivially accessible to any internet-connected attacker targeting WordPress sites running this payment gateway plugin. …

Vulnerability AssessmentAI

Exploitation No authentication is required (CVSS PR:N confirmed), the attack is executable over the network without special positioning (AV:N), requires no user interaction (UI:N), and has low attack complexity (AC:L), consistent with a default installation of the plugin on any internet-facing WordPress/WooCommerce site. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 6.5 (Medium) reflects a network-exploitable flaw with no prerequisites (AV:N/AC:L/PR:N/UI:N/S:U), but with constrained impact (C:N/I:L/A:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker enumerates a target WordPress site for the Flutterwave WooCommerce plugin (e.g., via plugin-specific asset fingerprinting), then crafts an HTTP request directly to the alternate authentication path - such as a webhook callback or payment notification endpoint - without supplying valid credentials. The plugin processes the request without enforcing authentication, allowing the attacker to trigger unintended functionality, potentially manipulating payment state or disrupting store availability. …
Remediation Update the Flutterwave WooCommerce plugin to a version beyond 3.3.0 via the WordPress plugin dashboard or by downloading the latest release from the WordPress plugin repository. … Detailed patch versions, workarounds, and compensating controls in full report.
