An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88621 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-88621/ (Markdown: https://insights.sbomify.com/CVE-2026-88621/index.md)","id":"CVE-2026-88621","markdown":"https://insights.sbomify.com/CVE-2026-88621/index.md","name":"CVE-2026-88621","record":{"aliases":["GHSA-52c3-83c9-5h54"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OneNav bookmark manager","requires_auth":"high_privilege","summary":"An authenticated administrator can delete arbitrary files in the application directory by manipulating upload filenames, leading to data loss or denial of service.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":2.7,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-706","name":"Use of Incorrectly-Resolved Name or Reference"}],"description":"OneNav v1.2.4 contains an authenticated arbitrary file deletion vulnerability in the Api::upload() method in class/Api.php.
