An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26045 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nodebb (npm): affected from 2.5.0; fixed in 2.8.7\n- nodebb (npm): affected from 2.5.0; fixed in 2.8.7\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-2023-26045/ (Markdown: https://insights.sbomify.com/CVE-2023-26045/index.md)","id":"CVE-2023-26045","markdown":"https://insights.sbomify.com/CVE-2023-26045/index.md","name":"CVE-2023-26045","record":{"aliases":["GHSA-vh2g-6c4x-5hmp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NodeBB forum software","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript files on the server via a path traversal flaw in the user export feature of NodeBB.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nodebb","vendor":"nodebb"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"NodeBB is Node.js based forum software. Starting in version 2.5.0 and prior to version 2.8.7, due to the use of the object destructuring assignment syntax in the user export code path, combined with a path traversal vulnerability, a specially crafted payload could invoke the user export logic to arbitrarily execute javascript files on the local disk. This issue is patched in version 2.8.7.
