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-2026-86721 in the wild and no public exploit code.\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-2026-86721/ (Markdown: https://insights.sbomify.com/CVE-2026-86721/index.md)","id":"CVE-2026-86721","markdown":"https://insights.sbomify.com/CVE-2026-86721/index.md","name":"CVE-2026-86721","record":{"aliases":["GHSA-5664-h9h4-3gwc","GHSA-x6f7-2rr5-x37c"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"AVideo streaming platform","requires_auth":"none","summary":"Attackers can hijack live broadcasts and publish to any user's RTMP stream without authentication by exploiting a session cookie override vulnerability.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","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-287","name":"Improper Authentication"}],"description":"AVideo through commit c3edcc274c contains an authorization bypass vulnerability where a session cookie named 'key' with value 'value' overrides the $_REQUEST['key'] parameter in saveLive.php and related endpoints.
