Affiliate Broken Access Control in Affiliates Manager <= 2.9.49 versions.

AnalysisAI

Broken Access Control in the Affiliates Manager WordPress plugin (versions <= 2.9.49) allows an authenticated low-privilege user to perform unauthorized affiliate management actions, achieving high integrity impact due to missing authorization checks (CWE-862). The CVSS vector (PR:L, AV:N, AC:L) confirms exploitation is network-accessible with minimal complexity, requiring only a valid low-privilege account. No active exploitation has been identified at time of analysis, and no patched version has been independently confirmed from the available intelligence.

Technical ContextAI

Affiliates Manager is a WordPress plugin that provides affiliate program management functionality, including tracking, payouts, and affiliate account administration. CWE-862 (Missing Authorization) indicates the plugin fails to verify whether the authenticated requestor holds the appropriate WordPress capability or role before executing sensitive affiliate-related operations. This class of flaw is common in WordPress plugins where REST API endpoints or admin-ajax handlers perform privileged actions without capability checks. The CVSS PR:L metric confirms the flaw is reachable by any authenticated WordPress user - such as a subscriber or a registered affiliate - not just editors or administrators. The 'Authentication Bypass' tag from Patchstack further indicates the missing check allows crossing a role boundary, effectively letting lower-privileged users exercise functions reserved for higher roles.

RemediationAI

Consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/affiliates-manager/vulnerability/wordpress-affiliates-manager-plugin-2-9-49-broken-access-control-vulnerability for the patched release version and update the plugin immediately once available. No specific patched version number was confirmed in the provided intelligence data - do not assume version 2.9.50 or higher is safe without verifying against the vendor changelog. As a compensating control while awaiting a patch, disable the Affiliates Manager plugin entirely on sites where affiliate functionality is non-critical. On sites where the plugin must remain active, restrict new user registrations and affiliate account creation to prevent untrusted users from obtaining the low-privilege foothold required for exploitation. Audit existing low-privilege user accounts for unusual affiliate management activity. These controls reduce exposure but do not eliminate the underlying flaw.
