## What is GHSA-5p98-wpc9-g498?

GHSA-5p98-wpc9-g498 is a server-side request forgery vulnerability in html-pdf-chrome, published on 4 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

## Recommendation
This package is working as intended. A [Security](https://github.com/westy92/html-pdf-chrome#security) section has been added since v0.6.1 to detail proper usage of this library. Npm has revoked their advisory altogether.

## Original Advisory
All versions of `html-pdf-chrome` are vulnerable to Server-Side Request Forgery (SSRF). The package executes HTTP requests if the parsed HTML contains external references to resources, such as `<iframe src="http://localhost" height="800px" width="800px"></iframe>`. This allows attackers to access resources through HTTP that are accessible to the server, including private resources in the hosting environment.

## Which versions are affected by GHSA-5p98-wpc9-g498?

2 open source packages ship an affected version, including html-pdf-chrome.


| Package | Ecosystem | Affected | Fixed in |
| --- | --- | --- | --- |
| `html-pdf-chrome` | npm | All versions | 0.6.1 |
| `html-pdf-chrome` | npm | All versions | 0.6.1 |

Affected packages and fixed versions:
- html-pdf-chrome (npm): affected all versions; fixed in 0.6.1
- html-pdf-chrome (npm): affected all versions; fixed in 0.6.1

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
