{"cve":"CVE-2025-54376","nvd":{"published":"2025-09-10T20:15:35.077","modified":"2026-06-17T09:39:56.870","status":"Analyzed","description":"Hoverfly is an open source API simulation tool. In versions 1.11.3 and prior, Hoverfly’s admin WebSocket endpoint /api/v2/ws/logs is not protected by the same authentication middleware that guards the REST admin API. Consequently, an unauthenticated remote attacker can stream real-time application logs (information disclosure) and/or gain insight into internal file paths, request/response bodies, and other potentially sensitive data emitted in logs. Version 1.12.0 contains a fix for the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","score":7.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-532","CWE-200","CWE-287"],"references":["https://github.com/SpectoLabs/hoverfly/commit/ffc2cc34563de67fe1a04f7ba5d78fa2d4564424","https://github.com/SpectoLabs/hoverfly/security/advisories/GHSA-jxmr-2h4q-rhxp"],"products":["hoverfly:hoverfly"],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2025-54376","score":0.00711,"percentile":0.53581,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jxmr-2h4q-rhxp","url":"https://osv.dev/vulnerability/GHSA-jxmr-2h4q-rhxp","summary":"WebSocket endpoint `/api/v2/ws/logs` reachable without authentication even when --auth is enabled","modified":"2025-09-24T21:14:07Z","packages":[{"ecosystem":"Go","name":"github.com/SpectoLabs/hoverfly","purl":"pkg:golang/github.com/SpectoLabs/hoverfly","ranges":["<1.12.0"],"fixed":["1.12.0"]}]},{"id":"GO-2025-3945","url":"https://osv.dev/vulnerability/GO-2025-3945","summary":"WebSocket endpoint `/api/v2/ws/logs` reachable without authentication even when --auth is enabled in github.com/SpectoLabs/hoverfly","modified":"2026-03-03T04:56:53.796552Z","packages":[{"ecosystem":"Go","name":"github.com/SpectoLabs/hoverfly","purl":"pkg:golang/github.com/SpectoLabs/hoverfly","ranges":["<1.12.0"],"fixed":["1.12.0"]}]}],"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).
