Summary
WWBN AVideo, a video platform, has a flaw in its PayPal payment handler (plugin/PayPalYPT/ipnV2.php) that lets an attacker add balance to a chosen user's wallet by forwarding genuine PayPal payment notifications from their own account. This can be done remotely, without logging in, and the attacker gains the ability to alter wallet credits, not to read or take over the site.
Read the original description
WWBN AVideo through 29.7.1 contains an improper payment verification vulnerability in plugin/PayPalYPT/ipnV2.php that credits wallets from PayPal IPNs not bound to the site's merchant account. Unauthenticated attackers can forward genuine VERIFIED recurring-payment IPNs from their own PayPal account with a chosen users_id to add wallet balance each billing cycle.
Who should check
Teams running WWBN AVideo up to 29.7.1 with the PayPalYPT and YPTWallet plugins and live PayPal payments

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-126543 (WWBN AVideo through 29.7.1 Wallet Credit Manipulation via PayPalYPT ipnV2.php), using the cve.now data below. Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-126543 (entry last updated 2026-11-11): Affected: - WWBN AVideo: through 29.7.1 Fixed versions: none listed yet. Conditions (all must be true for the bug to be hit): - Affected: every AVideo release that contains the ipnV2.php IPN branch, through 29.7.1 (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-5gg3-9jhh-xf86) - YPTWallet and PayPalYPT plugins enabled with live PayPal payments (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-5gg3-9jhh-xf86) - Wallet currency is USD (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-5gg3-9jhh-xf86) Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. Attacker needs: network access, no login, no user action. CISA KEV: CVE-2026-126543 is not listed as of cve.now's last read. This KEV status is for CVE-2026-126543 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory. Verify against the linked advisories before concluding, and cite the date you read each one: - https://github.com/WWBN/AVideo/security/advisories/GHSA-5gg3-9jhh-xf86 - https://github.com/WWBN/AVideo/commit/98406b7944e035e72082665ac886d78fc3af0a7f - https://github.com/WWBN/AVideo/blob/v29.7.1/plugin/PayPalYPT/ipnV2.php#L87-L125 - https://www.vulncheck.com/advisories/wwbn-avideo-through-29.7.1-wallet-credit-manipulation-via-paypalypt-ipnv2-php Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing. Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-126543
Is CVE-2026-126543 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The PayPal payment notification handler in ipnV2.php can be fed genuine PayPal IPN messages from a merchant account the attacker controls. Each replayed message adds the full payment amount to the wallet balance of a chosen user, repeated each billing cycle.Source: github.com
Which versions are affected by CVE-2026-126543?
AVideo: through 29.7.1.Source: cve.now feed data
Am I affected, and how do I check?
Every AVideo release through 29.7.1 that contains the ipnV2.php IPN branch is affected, but only when the YPTWallet and PayPalYPT plugins are enabled with live payments and the wallet currency is USD. To check, compare your AVideo version with 29.7.1 and review the enabled plugins and wallet currency in the admin settings.Source: github.com
How do I fix CVE-2026-126543?
The checked facts do not name a fixed version, so no upgrade target can be given from them. Check the vendor's advisory for a patched release, and until one is confirmed, limit exposure as described in the no-patch guidance.Source: github.com
