Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-50186 exists.\n\nAffected product: RARgames 4gaBoards. 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-2026-50186/ (Markdown: https://insights.sbomify.com/CVE-2026-50186/index.md)","id":"CVE-2026-50186","markdown":"https://insights.sbomify.com/CVE-2026-50186/index.md","name":"CVE-2026-50186","record":{"aliases":["GHSA-rv7w-hhqv-65cf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"4gaBoards project management","requires_auth":"low_privilege","summary":"An authenticated project manager can exploit path traversal in board exports to read and delete arbitrary files on the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"4gaBoards is a boards system for realtime project management. Prior to 3.3.8, 4gaBoards allows an authenticated project manager to supply traversal sequences in the filename parameter of GET /exports/:id/:filename. In server/api/controllers/boards/download.js, the decoded inputs.filename value is passed to path.join() beneath private/exports/\u003cuser_id\u003e/ without containment validation. A crafted value such as ../ can select an arbitrary file readable by the server process, and the file is returned to the attacker. The fileStream close handler then passes the same path to fs.unlink(), deleting the selected file and potentially causing data loss or denial of service. This issue is fixed in version 3.3.8.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"4gaBoards: Path Traversal leading to Arbitrary File Read and Deletion in Board Export","id":"CVE-2026-50186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Oh My Zsh: Arbitrary Code Execution in oh-my-zsh dotenv plugin via malicious .env files","id":"CVE-2026-50187"},"packages":[],"prev":{"headline":"RustCrypto Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set","id":"CVE-2026-50185"},"products":["4gaBoards"],"published":"2026-08-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["RARgames"]},"summary":"An authenticated project manager can exploit path traversal in board exports to read and delete arbitrary files on the server.","url":"https://insights.sbomify.com/CVE-2026-50186/"}
