Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-23488 in the wild and no public exploit code.\n\nAffected product: bigbluebutton. 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-2022-23488/ (Markdown: https://insights.sbomify.com/CVE-2022-23488/index.md)","id":"CVE-2022-23488","markdown":"https://insights.sbomify.com/CVE-2022-23488/index.md","name":"CVE-2022-23488","record":{"aliases":["GHSA-j5g3-f74q-rvfq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Web conferencing system","requires_auth":"low_privilege","summary":"Attackers can view viewers' webcams despite moderator-only lock settings due to missing backend authorization checks in BigBlueButton.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"bigbluebutton","vendor":"bigbluebutton"}],"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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"BigBlueButton is an open source web conferencing system. Versions prior to 2.4-rc-6 are vulnerable to Insertion of Sensitive Information Into Sent Data. The moderators-only webcams lock setting is not enforced on the backend, which allows an attacker to subscribe to viewers' webcams, even when the lock setting is applied.
