DescriptionCVE.org

Unauthenticated Cross Site Scripting (XSS) in Affiliates Manager <= 2.9.53 versions.

AnalysisAI

Unauthenticated Cross-Site Scripting in the Affiliates Manager WordPress plugin (versions ≤2.9.53) allows remote attackers without credentials to inject arbitrary JavaScript that executes in the browser context of site visitors or authenticated administrators. The CVSS scope change (S:C) indicates the injected script breaks out of the plugin's trust boundary and operates under the victim's session, enabling session hijacking or unauthorized privileged actions. …

Vulnerability AssessmentAI

Exploitation No authentication is required - the vulnerability is confirmed exploitable by unauthenticated remote attackers (PR:N per CVSS vector and 'Unauthenticated' per CVE description). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS score of 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L reflects a network-exploitable, low-complexity attack requiring no privileges, constrained primarily by the need for victim interaction (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a URL targeting the vulnerable WordPress site with a malicious JavaScript payload embedded in a parameter processed by the Affiliates Manager plugin, then delivers it via a phishing email to a logged-in WordPress administrator. When the admin loads the link, the script executes under the admin's authenticated browser session, allowing the attacker to exfiltrate session cookies, create new administrator accounts, or install a malicious plugin - achieving persistent site compromise without ever authenticating directly.
Remediation Update the Affiliates Manager plugin to a version above 2.9.53 immediately via the WordPress admin dashboard under Plugins > Installed Plugins > Update. … Detailed patch versions, workarounds, and compensating controls in full report.
