How severe is GHSA-gwch-7m8v-7544?

No CVSS score has been assigned to GHSA-gwch-7m8v-7544 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-gwch-7m8v-7544?

GHSA-gwch-7m8v-7544 affects the following packages: github.com/bpg/terraform-provider-proxmox (Go). Ecosystems affected: Go.

How do I fix GHSA-gwch-7m8v-7544?

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.

How do I detect GHSA-gwch-7m8v-7544 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/bpg/terraform-provider-proxmox, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-gwch-7m8v-7544 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-gwch-7m8v-7544?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-gwch-7m8v-7544 can be triaged on real exposure rather than presence alone.

Is GHSA-gwch-7m8v-7544 actively exploited in the wild?

No public exploit code has been indexed for GHSA-gwch-7m8v-7544 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-gwch-7m8v-7544?

GHSA-gwch-7m8v-7544 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 38th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-gwch-7m8v-7544?

GHSA-gwch-7m8v-7544 is classified as Path Traversal (CWE-22), CWE-1188 (CWE-1188). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-gwch-7m8v-7544 published, and has it been updated?

GHSA-gwch-7m8v-7544 was published on February 2, 2026 and was last updated on February 5, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Proof-of-concept exploit code exists

CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

Real-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
