CVE-2026-72747 WWBN CVE debrief
AVideo stored cross-site scripting via unauthenticated registration. The vulnerability allows unauthenticated attackers to inject malicious JavaScript, which can be executed in administrators' browser sessions when they visit the users management page. This occurs because AVideo fails to sanitize the phone field during user registration, allowing the injected script to persist in the database. The vulnerability has a CVSS score of 5.1 and MEDIUM severity, indicating a moderate risk. Defenders should prioritize verifying and sanitizing user input, especially phone fields, during registration to prevent potential XSS attacks.

- Administrators' management pages may be vulnerable to XSS attacks if not properly sanitized.
- The vulnerability has a CVSS score of 5.1 and MEDIUM severity, indicating a moderate risk.
Technical summary
AVideo fails to sanitize the phone field during user registration, allowing unauthenticated attackers to inject malicious JavaScript that persists in the database. When administrators visit the users management page, the unsanitized phone value is rendered via innerHTML, executing the injected script in the admin's browser session. The vulnerability has a CVSS score of 5.1 and MEDIUM severity, indicating a moderate risk. Defenders should prioritize verifying and sanitizing user input, especially phone fields, during registration to prevent potential XSS attacks. AVideo's failure to sanitize user input allows attackers to inject malicious scripts, which can be executed in administrators' browser sessions.
Defensive priority
Administrators should prioritize verifying and sanitizing user input, especially phone fields, during registration to prevent potential XSS attacks.
Recommended defensive actions
- Verify and sanitize user input, especially phone fields, during registration to prevent potential XSS attacks.
- Review and update administrators' management pages to ensure proper rendering and sanitization of user-provided data.
- Consider implementing additional security measures, such as Content Security Policy (CSP), to mitigate XSS attacks.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
