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. As a workaround, site maintainers can cherry pick the fix into their codebase to patch the exploit.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-22"],"references":["https://github.com/NodeBB/NodeBB/commit/ec58700f6dff8e5b4af1544f6205ec362b593092","https://github.com/NodeBB/NodeBB/security/advisories/GHSA-vh2g-6c4x-5hmp","https://security.netapp.com/advisory/ntap-20230831-0004/","https://github.com/NodeBB/NodeBB/commit/ec58700f6dff8e5b4af1544f6205ec362b593092","https://github.com/NodeBB/NodeBB/security/advisories/GHSA-vh2g-6c4x-5hmp"],"products":["nodebb:nodebb"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-26045","score":0.01029,"percentile":0.63685,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vh2g-6c4x-5hmp","url":"https://osv.dev/vulnerability/GHSA-vh2g-6c4x-5hmp","summary":"Path traversal and code execution via prototype vulnerability","modified":"2026-09-10T03:49:57.256523361Z","packages":[{"ecosystem":"npm","name":"nodebb","purl":"pkg:npm/nodebb","ranges":[">=2.5.0 <2.8.7"],"fixed":["2.8.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
