Impact The Microsoft Graph Beta PHP SDK published packages which contained test code that enabled the use of the phpInfo() function from any application that could access and execute the file at vendor/microsoft/microsoft-graph-beta/tests/GetPhpInfo.php. The phpInfo function exposes system information. The vulnerability affects the GetPhpInfo.php script of the PHP SDK which contains a call to the phpinfo() function. This vulnerability requires a misconfiguration of the server to be present so it can be exploited. For example, making the PHP application’s /vendor directory web accessible. The combination of the vulnerability and the server misconfiguration would allow an attacker to craft an HTTP request that executes the phpinfo() method. The attacker would then be able to get access to system information like configuration, modules, and environment variables and later on use the compromised secrets to access additional data.

# Patch Next advisory brief: GHSA-7mc6-x925-7qvx

Advisory: Test code in published microsoft-graph-beta package exposes phpinfo()
IDs: GHSA-7mc6-x925-7qvx
Record: https://patchnext.com/advisories/ghsa-7mc6-x925-7qvx (revision 1, source checked 26 Oct 2026, 14:11 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: microsoft/microsoft-graph-beta 2.0.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist microsoft/microsoft-graph-beta: affected < 2.0.1; fixed in 2.0.1

## Suggested inspection (read-only)
- Packagist microsoft/microsoft-graph-beta: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on microsoft/microsoft-graph-beta.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-7mc6-x925-7qvx (GitHub-reviewed advisory GHSA-7mc6-x925-7qvx lists affected ranges: Packagist microsoft/microsoft-graph-beta >=0 <2.0.1)
