{"cve":"CVE-2026-55102","nvd":{"published":"2026-09-14T17:17:47.930","modified":"2026-09-30T19:57:08.043","status":"Deferred","description":"hashi-vault-js is a Node.js module for interacting with the HashiCorp Vault API. Prior to 0.5.2, every API method in src/Vault.js passes failed requests through parseAxiosError(), which rethrows the raw AxiosError while retaining AxiosError.config and the equivalent response configuration. These objects can contain the X-Vault-Token request header and err.config.data request body, including submitted passwords or secret values. When a consuming application records the caught exception through console logging, structured loggers, monitoring, crash reporting, or an application performance monitoring service, the live Vault token and request secrets can be stored in plaintext and exposed to anyone with access to that output. A stolen token can permit unauthorized access to the Vault instance under the token's policies. This issue is fixed in version 0.5.2.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N","score":5.8},"cvss_v3":null,"cwes":["CWE-209","CWE-532"],"references":["https://github.com/kyndryl-open-source/hashi-vault-js/commit/ed0797a2d09c1fe0fd20764dde66cbc29241d9fb","https://github.com/kyndryl-open-source/hashi-vault-js/pull/67","https://github.com/kyndryl-open-source/hashi-vault-js/releases/tag/v0.5.2","https://github.com/kyndryl-open-source/hashi-vault-js/security/advisories/GHSA-5pq8-3ffp-7w5m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-55102","score":0.00161,"percentile":0.05255,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5pq8-3ffp-7w5m","url":"https://osv.dev/vulnerability/GHSA-5pq8-3ffp-7w5m","summary":"hashi-vault-js: Vault token and secret values exposed in thrown errors","modified":"2026-08-13T14:41:01.148534Z","packages":[{"ecosystem":"npm","name":"hashi-vault-js","purl":"pkg:npm/hashi-vault-js","ranges":["<0.5.2"],"fixed":["0.5.2"]}]}],"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).
