An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-24890 exists.\n\nAffected product: nextcloud security-advisories. 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-2022-24890/ (Markdown: https://insights.sbomify.com/CVE-2022-24890/index.md)","id":"CVE-2022-24890","markdown":"https://insights.sbomify.com/CVE-2022-24890/index.md","name":"CVE-2022-24890","record":{"aliases":["GHSA-vxpr-hcqq-7fw7"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Talk","requires_auth":"high_privilege","summary":"A call moderator can indirectly enable user webcams by granting permissions, exposing private video feeds to unauthorized actors.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"talk","vendor":"nextcloud"}],"cvss":{"score":2.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"},{"id":"CWE-359","name":"Exposure of Private Personal Information to an Unauthorized Actor"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Nextcloud Talk is a video and audio conferencing app for Nextcloud.
