WWBN AVideo contains a cross-site request forgery vulnerability in sendEmail.json.php that allows authenticated administrators to send mail from the site's contact address by bypassing origin checks and captcha validation. Attackers can craft a malicious web page that, when visited by an authenticated admin, sends emails with attacker-controlled subject and body to arbitrary recipients, passing SPF/DKIM/DMARC validation for phishing and brand impersonation attacks.
AnalysisAI
Cross-site request forgery in WWBN AVideo's sendEmail.json.php endpoint enables network-based abuse of an authenticated administrator's session to dispatch arbitrary emails from the site's legitimate contact address. When an admin is tricked into visiting a malicious page while logged in, the attacker controls the email subject, body, and recipient list - and because the server sends the message itself, it passes SPF/DKIM/DMARC authentication, making it a viable phishing and brand impersonation vector. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim be an authenticated AVideo administrator with an active, valid session cookie - standard user accounts are insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N, score 5.3) accurately reflects a moderate-severity issue gated entirely on social engineering: the attacker needs no credentials of their own but must induce an authenticated admin to visit a malicious page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Administrators should consult the GitHub Security Advisory (https://github.com/WWBN/AVideo/security/advisories/GHSA-7h9v-f3gg-r3mq) and apply any patch or updated release published by WWBN; no specific fixed version was confirmed in the available intelligence, so the WWBN AVideo release page should be monitored for a patched build. … Detailed patch versions, workarounds, and compensating controls in full report. |
