How do I fix GHSA-rwj2-w85g-5cmm?

Update github.com/patrickhener/goshs to 1.0.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rwj2-w85g-5cmm is resolved across your whole dependency graph.

How do I detect GHSA-rwj2-w85g-5cmm in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/patrickhener/goshs. 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.

How do I mitigate GHSA-rwj2-w85g-5cmm 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-rwj2-w85g-5cmm?

O3 pinpoints whether GHSA-rwj2-w85g-5cmm is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-rwj2-w85g-5cmm actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-rwj2-w85g-5cmm, including . All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-rwj2-w85g-5cmm?

GHSA-rwj2-w85g-5cmm has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 44th 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-rwj2-w85g-5cmm?

GHSA-rwj2-w85g-5cmm is classified as CWE-77 (CWE-77), CWE-284 (CWE-284). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Summary

It seems that when running goshs without arguments it is possible for anyone to execute commands on the server. This was tested on version 1.0.4 of goshs. The command function was introduced in version 0.3.4.

Details

It seems that the function dispatchReadPump does not checks the option cli -c, thus allowing anyone to execute arbitrary command through the use of websockets.

PoC

Used websocat for the POC:

echo -e '{"type": "command", "content": "id"}' |./websocat 'ws://192.168.1.11:8000/?ws' -t

Impact

The vulnerability will only impacts goshs server on vulnerable versions.
