## Reporting a Vulnerability
|
||
|
||
**Please do not open a public GitHub issue for security vulnerabilities.**
|
||
|
||
If you discover a security vulnerability — or suspect one — follow responsible disclosure:
|
||
|
||
1. **Email** the maintainer directly at **[info@tecnick.com](mailto:info@tecnick.com)** with the subject line:
|
||
`[SECURITY] tc-lib-pdf-image – <brief description>`
|
||
2. Include as much detail as possible (see [What to include](#what-to-include) below).
|
||
3. You will receive an acknowledgement as soon as possible.
|
||
4. We will work on a fix or mitigation as promptly as the complexity of the issue allows.
|
||
|
||
If you do not receive a timely response, please follow up by replying to the same email thread.
|
||

||
## What to Include
|
||
|
||
A high-quality report helps us triage and fix issues faster. Please provide:
|
||
|
||
- **Description** — a clear summary of the vulnerability and its potential impact.
|
||
- **Affected component** — which class, method, or feature is involved (e.g., `HTML::render()`, font loading, image processing).
|
||
- **Steps to reproduce** — a minimal, self-contained PHP script or unit test that demonstrates the issue.
|
||
- **Expected vs. actual behaviour** — what you expected to happen and what actually happened.
|
||
- **Environment** — PHP version, OS, library version (output of `composer show tecnickcom/tc-lib-pdf-image`).
|
||
- **CVE / CWE reference** (optional) — if you have already identified a relevant classification.
|
||
- **Suggested fix** (optional) — a patch or proposed mitigation if you have one.

## Security Best Practices for Integrators
|
||
|
||
Integrators are responsible for sanitising input **before** passing it to the library. We recommend:
|
||
|
||
- **Validate and sanitise all user-supplied data**. Use a dedicated sanitiser when accepting content from end users.
|
||
- **Keep dependencies up to date.** Run `composer update` regularly and monitor advisories via [Packagist Security Advisories](https://packagist.org/packages/tecnickcom/tc-lib-pdf-image) or tools such as `composer audit`.
|
||
- **Pin versions in production.** Use `composer.lock` and review changes on every update.
