Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23484 in the wild and no public exploit code.\n\nAffected product: blinkospace blinko. 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-2026-23484/ (Markdown: https://insights.sbomify.com/CVE-2026-23484/index.md)","id":"CVE-2026-23484","markdown":"https://insights.sbomify.com/CVE-2026-23484/index.md","name":"CVE-2026-23484","record":{"aliases":["GHSA-7v3f-v6vf-jm9q"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Blinko note-taking app","requires_auth":"low_privilege","summary":"Authenticated users can exploit path traversal in Blinko to write arbitrary files, potentially leading to code execution or data modification.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"blinko","vendor":"blinko"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Blinko is an AI-powered card note-taking project.
