It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-12779 in the wild and no public exploit code.\n\nAffected product: Amazon WorkSpaces. 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-2025-12779/ (Markdown: https://insights.sbomify.com/CVE-2025-12779/index.md)","id":"CVE-2025-12779","markdown":"https://insights.sbomify.com/CVE-2025-12779/index.md","name":"CVE-2025-12779","record":{"aliases":["GHSA-mcg2-rcmm-mhww"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Amazon WorkSpaces client","requires_auth":"low_privilege","summary":"A local attacker can extract another user's authentication token from the Amazon WorkSpaces Linux client to access their WorkSpace.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-497","name":"Exposure of Sensitive System Information to an Unauthorized Control Sphere"}],"description":"Improper handling of the authentication token in the Amazon WorkSpaces client for Linux, versions 2023.0 through 2024.8, may expose the authentication token for DCV-based WorkSpaces to other local users on the same client machine.
