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.","published":"2026-07-16T19:12:56.106Z","modified":"2026-08-12T03:51:26.057864849Z","cvss":null,"epss":{"score":0.00669,"percentile":0.49326,"asOf":"2026-08-27"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"whistle","fixedVersion":"2.10.3"}],"fix":{"url":"https://github.com/avwo/whistle/commit/777bcf69bae2972aa7138a158c91619185653cf5","label":"avwo/whistle@777bcf6"},"references":[{"type":"WEB","url":"http://github.com/avwo/whistle/releases/tag/v2.10.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55629.json"},{"type":"ADVISORY","url":"https://github.com/avwo/whistle/security/advisories/GHSA-3vfr-4gwf-qxfp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55629"},{"type":"FIX","url":"https://github.com/avwo/whistle/commit/777bcf69bae2972aa7138a158c91619185653cf5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.057864849Z"}}
