Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory. This affects WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0 and 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, WSO2 Open Banking AM 1.4.0 up to 2.0.0 and WSO2 Open Banking KM 1.4.0, up to 2.0.0.

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Multiple WSO2 products have been identified as vulnerable due to improper output encoding, a Stored Cross Site Scripting (XSS) attack can be carried out by an attacker injecting a malicious payload into the Registry feature of the Management Console.

Multiple WSO2 products have been identified as vulnerable due to an XML External Entity (XXE) attack abuses a widely available but rarely used feature of XML parsers to access sensitive information.

A reflected XSS issue exists in the Management Console of several WSO2 products. This affects API Manager 2.2.0, 2.5.0, 2.6.0, 3.0.0, 3.1.0, 3.2.0, and 4.0.0; API Manager Analytics 2.2.0, 2.5.0, and 2.6.0; API Microgateway 2.2.0; Data Analytics Server 3.2.0; Enterprise Integrator 6.2.0, 6.3.0, 6.4.0, 6.5.0, and 6.6.0; IS as Key Manager 5.5.0, 5.6.0, 5.7.0, 5.9.0, and 5.10.0; Identity Server 5.5.0, 5.6.0, 5.7.0, 5.9.0, 5.10.0, and 5.11.0; Identity Server Analytics 5.5.0 and 5.6.0; and WSO2 Micro Integrator 1.0.0.
