| Vulnerability | Title and context | CVSS | EPSS | PoCs | Signals | STIX action |
|---|---|---|---|---|---|---|
Hoverfly: Denial of Service via Goroutine Leak in Remote Post-Serve Actions### Summary: Remote post-serve actions use `http.DefaultClient` without any timeout configuration. When the remote endpoint is unreachable or intentionally slow (accepts TCP connection but never responds), each triggered proxy request spawns a goroutine that blocks indefinitely on `http.DefaultClient.Do()`. An attacker can cause unbounded goroutine accumulation leading to memory exhaustion and process crash (OOM kill). Unlike local post-serve action execution, this requires no binary execution,… | CVSS-v3.1 | EPSS- | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
Hoverfly: Process Crash via Concurrent Map Write Race Condition in Diff Mode### Summary: When Hoverfly is running in Diff mode, the `AddDiff()` function writes to the shared `responsesDiff` map without any synchronization (no mutex). When multiple proxy requests are processed concurrently (the normal case for any proxy), the concurrent map writes trigger Go's built-in race detector which causes a `fatal error: concurrent map read and map write`, immediately killing the entire Hoverfly process. This is trivially exploitable by sending multiple simultaneous requests. ##… | CVSS-v3.1 | EPSS- | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2025-54376HIGH | Hoverfly's WebSocket endpoint `/api/v2/ws/logs` reachable without authentication even when --auth is enabled.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. | CVSS7.8v4.0 | EPSS0.705% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-54123CRITICAL | Hoverfly vulnerable to remote code execution at `/api/v2/hoverfly/middleware` endpoint due to insecure middleware implementationHoverfly is an open source API simulation tool. In versions 1.11.3 and prior, the middleware functionality in Hoverfly is vulnerable to command injection vulnerability at `/api/v2/hoverfly/middleware` endpoint due to insufficient validation and sanitization in user input. The vulnerability exists in the middleware management API endpoint `/api/v2/hoverfly/middleware`. This issue is born due to combination of three code level flaws: Insufficient Input Validation in middleware.go line 94-96; Unsaf… | CVSS9.8v3.1 | EPSS10.5% | PoCs5 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |
Arbitrary file read in the `/api/v2/simulation` endpoint in hoverfly (`GHSL-2023-274`)Hoverfly is a lightweight service virtualization/ API simulation / API mocking tool for developers and testers. The `/api/v2/simulation` POST handler allows users to create new simulation views from the contents of a user-specified file. This feature can be abused by an attacker to read arbitrary files from the Hoverfly server. Note that, although the code prevents absolute paths from being specified, an attacker can escape out of the `hf.Cfg.ResponsesBodyFilesPath` base path by using `../` segm… | CVSS-v4.0 | EPSS55.9% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |
