# CVE-2026-62253: Homer: Complete Authentication Bypass When coordinator.jwt.secret Is Empty (Default)

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.4% , percentile 35: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 35% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/sipcapture/homer-app (Go) < 0.0.0-20260625093330-5e90809657c9, fixed in 0.0.0-20260625093330-5e90809657c9 . Check your lockfile, including transitive dependencies.

## What it is

Homer is open source telecom observability software. Prior to version 11.0.283, both JWT middleware functions (JWTMiddleware and JWTMiddlewareV4) immediately return next(c) when jwtSecret == "". The JWT secret defaults to an empty string. On a default installation, all protected API endpoints under /api/v1, /api/v3, and /api/v4 are completely unauthenticated. Version 11.0.283 patches the issue.

## Affected packages

- Go `github.com/sipcapture/homer-app` < 0.0.0-20260625093330-5e90809657c9 → fixed: 0.0.0-20260625093330-5e90809657c9

## Affected products (CVE record)

- sipcapture homer: < 11.0.283

## Severity

- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.42% probability of exploitation activity in the next 30 days; percentile 35.
