Prior to 2.10.3, lib/service/service.js handles GET /cgi-bin/temp/get by reading req.query.filename, joining it to TEMP_FILES_PATH only when it matches the temporary file pattern, and otherwise passing the user-supplied filename directly to getFile, allowing a remote attacker to read arbitrary files such as /etc/passwd. This issue is reported as fixed in version 2.10.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-22"],"references":["http://github.com/avwo/whistle/releases/tag/v2.10.3","https://github.com/avwo/whistle/commit/777bcf69bae2972aa7138a158c91619185653cf5","https://github.com/avwo/whistle/security/advisories/GHSA-3vfr-4gwf-qxfp","https://github.com/avwo/whistle/security/advisories/GHSA-3vfr-4gwf-qxfp"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-55629","score":0.00554,"percentile":0.45969,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3vfr-4gwf-qxfp","url":"https://osv.dev/vulnerability/GHSA-3vfr-4gwf-qxfp","summary":"Whistle vulnerable to path traversal","modified":"2026-08-26T00:54:29.262025646Z","packages":[{"ecosystem":"npm","name":"whistle","purl":"pkg:npm/whistle","ranges":["<2.10.3"],"fixed":["2.10.3"]}]}],"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).
