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-2026-126542 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\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-2026-126542/ (Markdown: https://insights.sbomify.com/CVE-2026-126542/index.md)","id":"CVE-2026-126542","markdown":"https://insights.sbomify.com/CVE-2026-126542/index.md","name":"CVE-2026-126542","record":{"aliases":["GHSA-9rvm-cfc4-q9g9","GHSA-r23m-jf94-h653"],"analysis":{"component_type":"web_application","exploitable_when_present":false,"fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"video platform","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated attackers can log in as any AVideo user, including administrators, by setting a victim's social login display name.","user_interaction":"not_required","vuln_class":"auth_bypass","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"WWBN AVideo 6.5 through 29.7.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user via Hybridauth social login display names.
