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-2026-7978 in the wild and no public exploit code.\n\nAffected product: Google Chrome. 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-2026-7978/ (Markdown: https://insights.sbomify.com/CVE-2026-7978/index.md)","id":"CVE-2026-7978","markdown":"https://insights.sbomify.com/CVE-2026-7978/index.md","name":"CVE-2026-7978","record":{"aliases":["DEBIAN-CVE-2026-7978","ECHO-8869-beac-fa6d","GHSA-vc4p-4fpj-c36p","MINI-rp9r-vvx4-fjjc"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome","requires_auth":"none","summary":"A remote attacker can achieve OS-level privilege escalation on Mac via malicious network traffic exploiting an inappropriate implementation in Chrome's Companion feature.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"Inappropriate implementation in Companion in Google Chrome on Mac prior to 148.0.7778.96 allowed a remote attacker to perform OS-level privilege escalation via malicious network traffic.
