| Field | Value | |---|---| | Ecosystem | Go | | Package | github.com/getkin/kin-openapi | | Affected versions | = 0.143.0 introduced in v0.2.0, PR 90, 2019-05-07; reproduced on HEAD 30e2923 | | Patched versions | 0.144.0 | --- Summary openapi3filter.ValidateRequest contains a...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference through the defaultContentParameterDecoder function. An attacker can cause the application to crash or abort request processing by sending a crafted HTTP request that targets an OpenAPI operation with a content...

GHSA-XG5G-26X8-CVF4 Budibase: DNS rebinding SSRF bypasses remain in OpenAPI import and REST query execution

Impact A builder-level user can make Budibase issue server-side HTTP requests to loopback or private-network targets by using DNS rebinding against two outbound fetch paths that are still not pinned to the validated DNS answer. The first path is OpenAPI query import. It validates the supplied...

Server-side Request Forgery (SSRF)

Overview @budibase/server is a Budibase Web Server Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the OpenAPI import and REST query execution processes. An attacker can access internal network resources by exploiting DNS rebinding to bypass outbound fetch...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication due to the unconditional substitution of a nil AuthenticationFunc with a no-op function in the Load process. An attacker can gain unauthorized access to protected endpoints by sending unauthenticated requests, as...

GHSA-R277-6W6Q-XMQW kin-openapi: ValidationHandler.Load() Fail-Open Authentication Bypass via NoopAuthenticationFunc Default

Summary ValidationHandler.Load in getkin/kin-openapi silently replaces a nil AuthenticationFunc with NoopAuthenticationFunc, which always returns nil without performing any credential check. Because this substitution happens unconditionally when the caller omits the field, every OpenAPI security...

Unsafe Dependency Resolution

Overview Affected versions of this package are vulnerable to Unsafe Dependency Resolution via the IsSafeFileReference function. An attacker can access or disclose files outside the intended package boundary by supplying a crafted percent-encoded or multi-encoded file reference in the OpenAPI...
