Which packages are affected by GHSA-2hw7-mxvj-m455?

GHSA-2hw7-mxvj-m455 affects the following packages: node-red-dashboard (npm). Ecosystems affected: npm.

How do I fix GHSA-2hw7-mxvj-m455?

Update node-red-dashboard to 2.26.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2hw7-mxvj-m455 is resolved across your whole dependency graph.

How do I detect GHSA-2hw7-mxvj-m455 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-red-dashboard, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-2hw7-mxvj-m455 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-2hw7-mxvj-m455?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-2hw7-mxvj-m455 can be triaged on real exposure rather than presence alone.

Is GHSA-2hw7-mxvj-m455 actively exploited in the wild?

No public exploit code has been indexed for GHSA-2hw7-mxvj-m455 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-2hw7-mxvj-m455?

GHSA-2hw7-mxvj-m455 has an EPSS (Exploit Prediction Scoring System) score of 18.5%, placing it in the 97th 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 warrants monitoring and prompt remediation.

What type of vulnerability is GHSA-2hw7-mxvj-m455?

GHSA-2hw7-mxvj-m455 is classified as Path Traversal (CWE-22). This weakness type 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.

Is there exploit tooling available for GHSA-2hw7-mxvj-m455?

A Nuclei detection template exists for GHSA-2hw7-mxvj-m455, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-2hw7-mxvj-m455 published, and has it been updated?

GHSA-2hw7-mxvj-m455 was published on January 29, 2021 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.
