An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-126543 in the wild and no public exploit code.\nExposure: Only installations with a non-default setting turned on are exposed.\n\nAffected product: WWBN AVideo. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-126543/ (Markdown: https://insights.sbomify.com/CVE-2026-126543/index.md)","id":"CVE-2026-126543","markdown":"https://insights.sbomify.com/CVE-2026-126543/index.md","name":"CVE-2026-126543","record":{"aliases":["GHSA-5gg3-9jhh-xf86","GHSA-r4j2-2784-v3cx"],"analysis":{"component_type":"web_application","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"video platform","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated attackers can forward PayPal IPNs to AVideo to add wallet balance for chosen users; AVideo sites using PayPalYPT should care.","user_interaction":"not_required","vuln_class":"business_logic","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"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.
