Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33731 exists.\n\nAffected packages and fixed versions:\n- wwbn/avideo (Packagist): affected all versions; fixed in 29.0\n- wwbn/avideo (Packagist): affected all versions; fixed in 29.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-33731/ (Markdown: https://insights.sbomify.com/CVE-2026-33731/index.md)","id":"CVE-2026-33731","markdown":"https://insights.sbomify.com/CVE-2026-33731/index.md","name":"CVE-2026-33731","record":{"aliases":["GHSA-95jh-7r58-xmxw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Video platform","requires_auth":"low_privilege","summary":"Attackers can forge webhook signatures to inflate wallet balances and activate premium subscriptions without payment, causing revenue loss.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"WWBN AVideo is an open source video platform. In versions prior to 29.0, the Authorize.Net webhook handler at plugin/AuthorizeNet/webhook.php contains a signature verification bypass that allows an attacker to forge webhook requests with arbitrary payment amounts and target user IDs. By supplying a valid transaction ID from a small legitimate purchase, the attacker bypasses signature validation and credits arbitrary wallet balances to any user account via attacker-controlled payload fields. Three flaws combine into an exploit chain: signature bypass via OR logic (webhook.php:33), payload values override API-fetched values (AuthorizeNet.php:169-171, webhook.php:44-48) and a missing approval check (webhook.php:61-75). By forging payment metadata, an attacker can credit arbitrary amounts to any user's wallet without a corresponding payment and include a  plans_id  to activate premium subscriptions (webhook.php:86-134), enabling free access to all paid and premium content and causing direct revenue loss to the platform owner.
