It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-12823 exists.\n\nAffected product: Browserbase Skills. 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-2026-12823/ (Markdown: https://insights.sbomify.com/CVE-2026-12823/index.md)","id":"CVE-2026-12823","markdown":"https://insights.sbomify.com/CVE-2026-12823/index.md","name":"CVE-2026-12823","record":{"aliases":["GHSA-vxfm-r32r-fgx3"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Browserbase Skills library","requires_auth":"low_privilege","summary":"Local attackers can exploit incorrect default permissions in the Autobrowse Trace Artifact Handler to escalate privileges within the Browserbase Skills library.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"},{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"A security flaw has been discovered in Browserbase Skills up to 20260526.
