GHSA-vj2m-9f5j-mpr5 has a CVSS score of 7.5/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-vj2m-9f5j-mpr5?

GHSA-vj2m-9f5j-mpr5 affects the following packages: github.com/vapor/vapor (SwiftURL). Ecosystems affected: SwiftURL.

How do I fix GHSA-vj2m-9f5j-mpr5?

Update github.com/vapor/vapor to 4.60.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vj2m-9f5j-mpr5 is resolved across your whole dependency graph.

How do I detect GHSA-vj2m-9f5j-mpr5 in my SwiftURL dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/vapor/vapor. 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-vj2m-9f5j-mpr5 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-vj2m-9f5j-mpr5?

O3 pinpoints whether GHSA-vj2m-9f5j-mpr5 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-vj2m-9f5j-mpr5 actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-vj2m-9f5j-mpr5, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. 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-vj2m-9f5j-mpr5?

GHSA-vj2m-9f5j-mpr5 has an EPSS (Exploit Prediction Scoring System) score of 1.9%, placing it in the 77th 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-vj2m-9f5j-mpr5?

GHSA-vj2m-9f5j-mpr5 is classified as CWE-190 (CWE-190). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-vj2m-9f5j-mpr5 published, and has it been updated?

GHSA-vj2m-9f5j-mpr5 was published on June 7, 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

Vapor is an HTTP web framework for Swift and middleware is a logic chain between the client and a Vapor route handler. FileMiddleware enables the serving of assets from the Public folder of a project to the client.

Vapor before 4.60.3 is vulnerable to denial of service due to an integer overflow when given invalid range headers while using FileMiddleware. This is patched in 4.60.3.
