AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the YPTWallet plugin where user-supplied CryptoWallet values are base64-encoded but not HTML-escaped before storage in wallet_log.information. Administrators viewing pending withdrawal requests in pendingRequests.php execute the stored markup in their session, allowing attackers to perform administrative actions via same-origin fetch requests.

Stored cross-site scripting in the YPTWallet plugin of WWBN AVideo (through commit c3edcc274c389816d434acadac07ee78eaf330c1) lets an authenticated low-privilege user plant malicious markup via a CryptoWallet configuration value that is base64-encoded but never HTML-escaped before being written to wallet_log.information. When an administrator reviews pending withdrawal requests in pendingRequests.php, the payload executes in their session, enabling attacker-driven administrative actions through same-origin fetch requests. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated low-privilege account (PR:L) able to set a CryptoWallet value in the YPTWallet plugin, and the YPTWallet plugin must be enabled/in use on the AVideo instance. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N, score 9.3) reflects a network-reachable, low-complexity attack that nonetheless requires attacker privileges (PR:L - a wallet-configuring account) and victim interaction (UI:P - an admin must open the pending-requests 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 | Upstream fix available (referenced via the GHSA advisory/commit); a specifically tagged patched release version was not provided in the input, so update to a build after commit c3edcc274c389816d434acadac07ee78eaf330c1 per the vendor advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-fvp5-q9jp-29mx. … Detailed patch versions, workarounds, and compensating controls in full report. |
