Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54319 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/daytonaio/daytona (Go): affected all versions; fixed in 0.186.0\n- github.com/daytonaio/daytona (Go): affected all versions; fixed in 0.186.0\n- github.com/daytonaio/daytona (Go): affected all versions; fixed in 0.186.0\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-2026-54319/ (Markdown: https://insights.sbomify.com/CVE-2026-54319/index.md)","id":"CVE-2026-54319","markdown":"https://insights.sbomify.com/CVE-2026-54319/index.md","name":"CVE-2026-54319","record":{"aliases":["GHSA-fjv8-j4p5-cr9m","GO-2026-5367"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Daytona sandbox runtime","requires_auth":"low_privilege","summary":"Attackers can mount arbitrary host paths into sandboxes via path traversal in volume IDs, enabling cross-tenant data access and host escape.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows.
