Prior to 1.8.2, index.js uses the caller-controlled options.fileName value in path.join(tempDir.name, fileName) without reducing it to a base name. A filename containing ../ can escape the temporary directory because path.basename() normalization is missing and write the supplied document buffer to an arbitrary path writable by the process, including an SSH authorized_keys file, a cron configuration, or a web root. This issue is fixed in version 1.8.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://github.com/elwerene/libreoffice-convert/commit/b78f17df9b9183bd503fc4635fc8b3df6705047b","https://github.com/elwerene/libreoffice-convert/security/advisories/GHSA-gmxc-r82q-347r"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-54732","score":0.00416,"percentile":0.35944,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-gmxc-r82q-347r","url":"https://osv.dev/vulnerability/GHSA-gmxc-r82q-347r","summary":"libreoffice-convert vulnerable to path traversal / arbitrary file write","modified":"2026-08-27T17:40:40.102977Z","packages":[{"ecosystem":"npm","name":"libreoffice-convert","purl":"pkg:npm/libreoffice-convert","ranges":["<1.8.2"],"fixed":["1.8.2"]}]}],"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).
