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

Impact

Allows an attacker to perform a DOS attack consisting of memory exhaustion on the host system.

Patches

Yes. Please upgrade to v1.2.6.

Workarounds

A workaround is to restrict the path prefix to the "GET" method. As shown below

func main() {
	r := mux.NewRouter()

	r.PathPrefix("/swagger/").Handler(httpSwagger.Handler(
		httpSwagger.URL("http://localhost:1323/swagger/doc.json"), //The url pointing to API definition
		httpSwagger.DeepLinking(true),
		httpSwagger.DocExpansion("none"),
		httpSwagger.DomID("#swagger-ui"),
	)).Methods(http.MethodGet)

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update github.com/swaggo/http-swagger to 1.2.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xg75-q3q5-cqmv is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
