Merge branch 'master' into fix/4554-encryption-docker-issue

basename() returns string and database column values are strings,
but get_latest_migration() and get_current_version() declare int
return types. PHP 8.0+ enforces strict return types and no longer
silently coerces strings to int, causing a TypeError on fresh
installs.

Fixes #4559

+# GitHub Actions
+
+This document describes the CI/CD workflows for OSPOS.
+
+## Build and Release Workflow (`.github/workflows/build-release.yml`)
+
+### Build Process
+- Setup PHP 8.2 with required extensions
+- Setup Node.js 20
+- Install composer dependencies
+- Install npm dependencies
+- Build frontend assets with Gulp
+
+### Docker Images
+- Build and push `opensourcepos` Docker image for multiple architectures (linux/amd64, linux/arm64)
+- On master: tagged with version and `latest`
+- On other branches: tagged with version only
+- Pushed to Docker Hub
+
+### Releases
+- Create distribution archives (tar.gz, zip)
+- Create/update GitHub "unstable" release on master branch only
+
+## Required Secrets
+
+To use this workflow, you need to add the following secrets to your repository:
+
+1. **DOCKER_USERNAME** - Docker Hub username for pushing images
+2. **DOCKER_PASSWORD** - Docker Hub password/token for pushing images
+
+### How to add secrets
+
+1. Go to your repository on GitHub
+2. Click **Settings** → **Secrets and variables** → **Actions**
+3. Click **New repository secret**
+4. Add `DOCKER_USERNAME` and `DOCKER_PASSWORD`
+
+The `GITHUB_TOKEN` is automatically provided by GitHub Actions.
+
+## Workflow Triggers
+
+- **Push to master** - Runs build, Docker push (with `latest` tag), and release
+- **Push to other branches** - Runs build and Docker push (version tag only)
+- **Push tags** - Runs build and Docker push (version tag only)
+- **Pull requests** - Runs build only (PHPUnit tests run in parallel via phpunit.yml)
+
+## Existing Workflows
+
+This repository also has these workflows:
+- `.github/workflows/main.yml` - PHP linting with PHP-CS-Fixer
+- `.github/workflows/phpunit.yml` - PHPUnit tests (runs on all PHP versions 8.1-8.4)
+- `.github/workflows/php-linter.yml` - PHP linting
+
+## Testing
+
+PHPUnit tests are run separately via `.github/workflows/phpunit.yml` on every push and pull request, testing against PHP 8.1, 8.2, 8.3, and 8.4.
+
+To test the build workflow:
+1. Add the required secrets
+2. Push to master or create a PR
+3. Monitor the Actions tab in GitHub

+### Allowed Hostnames (REQUIRED for Production)
 
-OpenSourcePOS validates the Host header against a whitelist to prevent Host Header Injection attacks (GHSA-jchf-7hr6-h4f3). **You must configure this for production deployments.**
+⚠️ **CRITICAL**: OpenSourcePOS validates the Host header to prevent Host Header Injection attacks (GHSA-jchf-7hr6-h4f3). **You MUST configure `app.allowedHostnames` for production deployments. If not configured, the application will fail to start.**
 
-Add the following to your `.env` file:
+**Add to your `.env` file:**
 
-```
-app.allowedHostnames.0 = 'yourdomain.com'
-app.allowedHostnames.1 = 'www.yourdomain.com'
+```bash
+# Comma-separated list of allowed hostnames (no protocols or ports)
+app.allowedHostnames = 'yourdomain.com,www.yourdomain.com'

-**For local development**, use:
-```
-app.allowedHostnames.0 = 'localhost'
+**For local development:**
+
+```bash
+app.allowedHostnames = 'localhost'
 ```
 
-If `allowedHostnames` is not configured:
-1. A security warning will be logged
-2. The application will fall back to 'localhost' as the hostname
-3. This means URLs generated by the application (links, redirects, etc.) will point to 'localhost'
+**If you see this error at startup:**
+
+```text
+RuntimeException: Security: allowedHostnames is not configured.
+```
+
+**Solution**: Add `app.allowedHostnames` to your `.env` file with your domain(s).
+
+**Why this matters:**
+- Prevents Host Header Injection attacks (GHSA-jchf-7hr6-h4f3)
+- Ensures URLs are generated with the correct domain
+- Security advisory: https://github.com/opensourcepos/opensourcepos/security/advisories/GHSA-jchf-7hr6-h4f3

 ## Reporting a Vulnerability
 
-Please report (suspected) security vulnerabilities to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**. 
+**Option 1: GitHub Security Advisory (Preferred)**
 
-You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible depending on complexity but historically within a few days.
+1. Create a draft security advisory directly on GitHub:
+   - Go to https://github.com/opensourcepos/opensourcepos/security/advisories
+   - Click "New draft security advisory"
+   - Fill in the vulnerability details using our [template below](#vulnerability-template)
+   - Submit as **draft** (not published)
+
+2. Notify us for triage:
+   - Send an email to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)** with:
+     - Subject: `[GHSA] Brief description of vulnerability`
+     - Link to the draft advisory
+     - Brief summary
+
+**Option 2: Email Report**
+
+Send vulnerability details to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**.
+
+You will receive a response within 48 hours. Confirmed vulnerabilities will be patched within a few days depending on complexity.
+
+## Disclosure Process
+
+### Timeline
+
+| Step | Timeline | Action |
+|------|----------|--------|
+| 1. Report received | Day 0 | We acknowledge within 48 hours |
+| 2. Triage & confirmation | Day 1-3 | We validate the vulnerability |
+| 3. Fix development | Day 3-7 | We develop and test the fix |
+| 4. Patch release | Day 7-10 | We release a security patch |
+| 5. CVE request | Day 7-14 | We request CVE from GitHub (if applicable) |
+| 6. Advisory published | Day 14 | We publish the advisory with credit |
+| 7. Public disclosure | Day 14+ | Full disclosure after patch release |
+
+### CVE Process
+
+**We request CVE identifiers through GitHub's security advisory system.** This is the preferred and easiest method:
+
+1. After we confirm and fix the vulnerability, we'll request a CVE through GitHub
+2. GitHub coordinates with MITRE on our behalf
+3. The CVE is automatically linked to the advisory
+4. You'll be credited as the reporter in the published advisory
+
+**Already have a CVE?** If you've already obtained a CVE from another source (e.g., VulDB, CVE.MITRE.ORG), please include it in your report or advisory. We'll update our advisory to reference the existing CVE.
+
+### No Bug Bounty Program
+
+**Important:** Open Source Point of Sale does not offer a bug bounty program.
+
+- All security research and vulnerability triage is done on a **voluntary basis** in our free time
+- We do not offer monetary rewards for vulnerability reports
+- We do credit reporters in published advisories (unless anonymity is requested)
+- We greatly appreciate the security research community's efforts to help improve project security
+
+### Security Best Practices for Researchers
+
+- **Do not** access, modify, or delete data that doesn't belong to you
+- **Do not** perform denial of service attacks
+- **Do not** publicly disclose vulnerabilities before we've had time to fix them
+- **Do** provide sufficient information to reproduce the vulnerability
+- **Do** allow us reasonable time to fix before public disclosure
+- **Do** report through official channels (GitHub advisories or email)
+
+### Vulnerability Template
+
+When creating a draft advisory, please include:
+
+```
+## Summary
+[Brief description of the vulnerability]
+
+## Impact
+- **Confidentiality:** [High/Medium/Low - what data can be exposed]
+- **Integrity:** [High/Medium/Low - what can be modified]
+- **Availability:** [High/Medium/Low - service disruption potential]
+- **Privilege Required:** [None/Low/High - authentication level needed]
+- **CVSS v3.1:** [Score] ([Vector string])
