GHSA-7mc6-x925-7qvx — microsoft/microsoft-graph…
MEDIUMGHSA-7mc6-x925-7qvx is a medium-severity (CVSS 5.3) vulnerability in microsoft/microsoft-graph-beta. A fix is available for microsoft/microsoft-graph-beta — see the affected versions and patch details below.
Test code in published microsoft-graph-beta package exposes phpinfo()
Real-World Exposure
microsoft/microsoft-graph-betaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
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.
Patches
This problem has been patched in dependencies of version 2.0.1.
Workarounds
If an immediate deployment with the updated vendor package is not available, you can perform the following temporary workarounds:
- delete the vendor/microsoft/microsoft-graph-beta/tests/GetPhpInfo.php file
- remove access to the /vendor directory will remove this vulnerability
- disable the phpinfo function

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for microsoft/microsoft-graph-beta, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update microsoft/microsoft-graph-beta to 2.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7mc6-x925-7qvx is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7mc6-x925-7qvx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-7mc6-x925-7qvx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-7mc6-x925-7qvx in your dependencies?
O3 Security finds GHSA-7mc6-x925-7qvx across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
