AVideo with YPTSocket plugin enabled contains a cross-site scripting vulnerability allowing unauthenticated attackers to execute arbitrary JavaScript in other users' browsers via the websocket callback mechanism. Attackers can send crafted socket messages with callback names resolving to global functions like avideoConfirmHTML that accept untrusted data and assign it to innerHTML, achieving script execution in the victim's origin without authentication or user interaction.
AnalysisAI
Unauthenticated cross-site scripting in AVideo's YPTSocket plugin allows remote attackers to execute arbitrary JavaScript in the browsers of connected users by sending crafted WebSocket messages. The attack leverages the plugin's WebSocket callback dispatch mechanism, which resolves attacker-controlled callback names to global JavaScript functions (e.g., avideoConfirmHTML) that assign untrusted message data directly to innerHTML without sanitization. …

Vulnerability AssessmentAI
| Exploitation | The YPTSocket plugin must be installed and enabled on the AVideo instance - this is a non-default optional plugin, not part of the core AVideo installation, which limits the exposed population. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 with vector AV:N/AC:L/AT:N/PR:N/UI:N/SC:L/SI:L/SA:N reflects a realistic picture: network-reachable, no prerequisites, no victim click required, but impact bounded to the subsequent (victim browser) system with low confidentiality and integrity ratings. … 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 | Consult the vendor's security advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-xpx7-h2x7-59qq for the patched release version, as no specific fix version number was provided in the available intelligence data - patch availability is per vendor advisory but the exact version is not independently confirmed from this dataset. … Detailed patch versions, workarounds, and compensating controls in full report. |
