GHSA-gwch-7m8v-7544
terraform-provider-proxmox has insecure sudo recommendation in the documentation
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
github.com/bpg/terraform-provider-proxmoxReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Note: It is uncertain whether this constitutes a vulnerability or should be filed as an issue instead.
Summary
In the SSH configuration documentation, the sudoer line that was suggested can be escalated to edit any files in the system.
Details
The following line were suggested for addition in the sudoers file:
terraform ALL=(root) NOPASSWD: /usr/bin/tee /var/lib/vz/*
But this is highly insecure as the folder can be escaped using ../ and any files can be edited on the system.
PoC
Using a terraform user with the previously mentioned line in the /etc/sudoers file, a /etc/sudoers.d/sudo file can be added using this command:
echo "ALL=(ALL) NOPASSWD:ALL" | tee /var/lib/vz/../../../etc/sudoers.d/sudo
This grants access to the full root of the node.
Impact
This breaches the access limits of the Terraform user.
Suggested workaround
Use a strict regex on the command to allow only the names that should be pushed by this user.
Example for cloudinit yaml files:
terraform ALL=(root) NOPASSWD: /usr/bin/tee /var/lib/vz/snippets/[A-Za-z0-9-]*\\.yaml

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/bpg/terraform-provider-proxmox. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/bpg/terraform-provider-proxmox to 0.93.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gwch-7m8v-7544 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 pinpoints whether GHSA-gwch-7m8v-7544 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-gwch-7m8v-7544. 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-gwch-7m8v-7544 in your dependencies?
O3 detects GHSA-gwch-7m8v-7544 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
