Deeper analysis
A cross-site scripting vulnerability tracked as CVE-2022-30690 affects the image403 functionality in WWBN AVideo version 11.6 and the development master commit 3f7c0364. The flaw, assigned CWE-79, permits arbitrary JavaScript execution when a specially crafted HTTP request is processed, carrying a CVSS 3.1 score of 6.1.
An unauthenticated attacker can exploit the issue by inducing an authenticated user to submit the malicious request, resulting in JavaScript execution within the context of the victim's session. This enables limited impacts on confidentiality and integrity without requiring elevated privileges beyond social engineering the target user.
Public references point to Talos Intelligence advisory TALOS-2022-1539 for detailed analysis and to the AVideo updateDb.v12.0.sql script as the mechanism for applying remediation changes. The EPSS score rose from lower values after the 2022 disclosure to a peak of 0.1514 in December 2025 before receding to the current 0.0981, indicating a later surge in exploitation interest that warrants renewed attention.
