Dragonfly Manager OAuth provider client_secret disclosure via unauthenticated GET /api/v1/oauth

2.9 LowFix available

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.4.4, manager/router/router.go registers GET /api/v1/oauth and GET /api/v1/oauth/:id without jwt.MiddlewareFunc() or RBAC(), while manager/handlers/oauth.go returns models.Oauth records and manager/models/oauth.go exposes Oauth.ClientSecret as client_secret in JSON. When an administrator has configured a GitHub or Google OAuth provider, an unauthenticated network client can reach GetOauth or GetOauths, load the stored models.Oauth record, and obtain the provider's client secret, client identifier, and redirect URL. The earlier GHSA-j8hf-cp34-g4j7 remediation protected the /jobs group only and did not protect these OAuth GET handlers. Disclosure of client_secret can enable abuse of the configured identity-provider integration, subject to the provider's redirect URI restrictions. This issue is fixed in 2.4.4.

Dragonfly Manager OAuth provider client_secret disclosure via unauthenticated GET /api/v1/oauth

Summary

The Dragonfly Manager exposes GET /api/v1/oauth and GET /api/v1/oauth/:id to unauthenticated clients. The response body deserializes the entire manager/models.Oauth struct, which includes the client_secret field. Any network-reachable attacker can read the OAuth client secrets configured for github or google providers, defeating the confidentiality guarantee of those secrets and enabling subsequent abuse against the connected identity providers.

Affected versions

github.com/dragonflyoss/dragonfly <= v2.4.3 (and current main at commit 46a8f1e). The vulnerable wiring is present back to the introduction of OAuth GET handlers and was not addressed by GHSA-j8hf-cp34-g4j7 / CVE-2026-24124, whose remediation only added jwt + rbac middleware to the /jobs group.

Privilege required

Unauthenticated. The only precondition is that an administrator has registered at least one OAuth provider via POST /api/v1/oauth (a one-time setup for tenants that enable GitHub / Google sign-in).

Vulnerable code

manager/router/router.go:134-140 (v2.4.3) — the /oauth group registration:

// Oauth.
oa := apiv1.Group("/oauth")
oa.POST("", jwt.MiddlewareFunc(), rbac, h.CreateOauth)
oa.DELETE(":id", jwt.MiddlewareFunc(), rbac, h.DestroyOauth)
oa.PATCH(":id", jwt.MiddlewareFunc(), rbac, h.UpdateOauth)
oa.GET(":id", h.GetOauth)
oa.GET("", h.GetOauths)

Note the asymmetry inside the same oa route group: POST, PATCH, and DELETE explicitly attach jwt.MiddlewareFunc(), rbac as per-route middleware, but the two GET handlers omit both. Compare with the sibling group three lines below at manager/router/router.go:143-148, the /clusters group:

c := apiv1.Group("/clusters", jwt.MiddlewareFunc(), rbac)
c.POST("", h.CreateCluster)
c.DELETE(":id", h.DestroyCluster)
c.PATCH(":id", h.UpdateCluster)
c.GET(":id", h.GetCluster)
c.GET("", h.GetClusters)

Here the middleware pair is attached once at the group level, so every verb on /clusters is guarded. The OAuth GETs are an unguarded sibling of the same primitive that GHSA-j8hf-cp34-g4j7 (Jan 2026) patched on the /jobs group. This is sibling-method-dispatch-target of the AP-012 sub-shape lens: same module, same router file, same anchor primitive ("group lacking JWT + RBAC"), parallel GET methods missed.

The handler at manager/handlers/oauth.go:127-141 returns the model directly:

func (h *Handlers) GetOauth(ctx *gin.Context) {
	var params types.OauthParams
	if err := ctx.ShouldBindUri(&params); err != nil {
		ctx.JSON(http.StatusUnprocessableEntity, gin.H{"errors": err.Error()})
		return
	}

	oauth, err := h.service.GetOauth(ctx.Request.Context(), params.ID)
	if err != nil {
		ctx.Error(err) // nolint: errcheck
		return
	}

	ctx.JSON(http.StatusOK, oauth)
}

manager/handlers/oauth.go:155-171 has the parallel list handler:

func (h *Handlers) GetOauths(ctx *gin.Context) {
	var query types.GetOauthsQuery
	if err := ctx.ShouldBindQuery(&query); err != nil {
		ctx.JSON(http.StatusUnprocessableEntity, gin.H{"errors": err.Error()})
		return
	}

	h.setPaginationDefault(&query.Page, &query.PerPage)
	oauth, count, err := h.service.GetOauths(ctx.Request.Context(), query)
	if err != nil {
		ctx.Error(err) // nolint: errcheck
		return
	}

	h.setPaginationLinkHeader(ctx, query.Page, query.PerPage, int(count))
	ctx.JSON(http.StatusOK, oauth)
}
