Which packages are affected by GHSA-75j7-w798-cwwx?

GHSA-75j7-w798-cwwx affects the following packages: github.com/arduino/arduino-create-agent (Go). Ecosystems affected: Go.

How do I fix GHSA-75j7-w798-cwwx?

Update github.com/arduino/arduino-create-agent to 1.3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-75j7-w798-cwwx is resolved across your whole dependency graph.

How do I detect GHSA-75j7-w798-cwwx in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/arduino/arduino-create-agent. 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-75j7-w798-cwwx 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-75j7-w798-cwwx?

O3 pinpoints whether GHSA-75j7-w798-cwwx 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-75j7-w798-cwwx actively exploited in the wild?

No public exploit code has been indexed for GHSA-75j7-w798-cwwx 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-75j7-w798-cwwx?

GHSA-75j7-w798-cwwx has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 27th 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.

When was GHSA-75j7-w798-cwwx published, and has it been updated?

GHSA-75j7-w798-cwwx was published on October 18, 2023 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

The vulnerability affects the endpoint /upload which handles request with the filename parameter. A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can escalate his privileges to those of the user running the Arduino Create Agent service via a crafted HTTP POST request. Further details are available in the references.

Fixed Version

1.3.3
