DescriptionCVE.org

AVideo through version 26.0 contains multiple unauthenticated list.json.php endpoints in payment plugins lacking authorization checks, exposing PayPal tokens, Authorize.Net webhooks, and Bitcoin transaction records. Unauthenticated attackers can retrieve all payment transaction data including agreement IDs, user financial records, and API responses via direct GET requests to vulnerable endpoints.

AnalysisAI

Unauthenticated information disclosure in AVideo through 26.0 exposes payment transaction records via multiple list.json.php endpoints in the PayPalYPT, AuthorizeNet, and BTCPayments plugins that lack User::isAdmin() authorization checks. Remote attackers can issue direct GET requests to harvest PayPal billing agreement IDs, Express Checkout tokens, Authorize.Net webhook payloads, and Bitcoin transaction records without credentials. …

Vulnerability AssessmentAI

Exploitation Requires only that the target AVideo instance (≤26.0) be network-reachable and have at least one of the PayPalYPT, AuthorizeNet, or BTCPayments plugins installed and enabled - these are bundled with AVideo and commonly present on monetized deployments. … 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:N/VC:H/VI:N/VA:N) scoring 8.7 accurately reflects a network-reachable, no-privilege, no-interaction data exposure with high confidentiality impact and no integrity or availability effect - consistent with a pure read-only authorization-bypass exfiltration. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker scans internet-exposed AVideo installations and issues an unauthenticated GET to /plugin/PayPalYPT/View/PayPalYPT_log/list.json.php, receiving a JSON dump of every PayPal transaction including agreement IDs, Express Checkout tokens, and stored API response bodies. The same one-line request is repeated against the AuthorizeNet and BTCPayments list endpoints to harvest webhook payloads and Bitcoin transaction records, which are then used for payment fraud, customer phishing, or correlation with leaked user data. …
Remediation Upstream fix available (commit 1729a955f8de7e26552eb728b3d1e6f4b1b9352e); released patched version not independently confirmed, so operators tracking tagged releases should monitor https://github.com/WWBN/AVideo/security/advisories/GHSA-wprj-9cvc-5w37 and upgrade beyond 26.0 once a fixed tag ships. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all AVideo deployments running version 26.0 or earlier with affected payment plugins; restrict network access to list.json.php endpoints in PayPalYPT, AuthorizeNet, and BTCPayments directories. …
