An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-53955 exists.\n\nAffected product: Kantar Media BigVoice2. 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-2023-53955/ (Markdown: https://insights.sbomify.com/CVE-2023-53955/index.md)","id":"CVE-2023-53955","markdown":"https://insights.sbomify.com/CVE-2023-53955/index.md","name":"CVE-2023-53955","record":{"aliases":["GHSA-gj7r-228j-689h"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Broadcast automation software","requires_auth":"none","summary":"Attackers can bypass authorization to access hidden resources and execute privileged functions in SOUND4 broadcast automation systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"big_voice2_firmware","vendor":"sound4"},{"product":"big_voice4_firmware","vendor":"sound4"},{"product":"first_firmware","vendor":"sound4"},{"product":"impact_eco_firmware","vendor":"sound4"},{"product":"impact_firmware","vendor":"sound4"},{"product":"pulse_eco_firmware","vendor":"sound4"},{"product":"pulse_firmware","vendor":"sound4"},{"product":"stream_extension","vendor":"sound4"},{"product":"wm2_firmware","vendor":"sound4"}],"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-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"SOUND4 IMPACT/FIRST/PULSE/Eco v2.x contains an insecure direct object reference vulnerability that allows attackers to bypass authorization and access hidden system resources.
