| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2024-8260 | A SMB force-authentication vulnerability exists in all versions of OPA for Windows prior to v0.68.0. The vulnerability exists because of improper input validation, allowing a user to pass an arbitrary SMB share instead of a Rego file as an argument to OPA CLI or to one of the OPA Go library’s functions. | [email protected] | 6.1 | 0.32% | 2024-08-30 | 2024-09-19 |
| CVE-2022-36085 | Open Policy Agent (OPA) is an open source, general-purpose policy engine. The Rego compiler provides a (deprecated) `WithUnsafeBuiltins` function, which allows users to provide a set of built-in functions that should be deemed unsafe — and as such rejected — by the compiler if encountered in the policy compilation stage. A bypass of this protection has been found, where the use of the `with` keyword to mock such a built-in function (a feature introduced in OPA v0.40.0), isn’t taken into account | [email protected] | 7.4 | 1.19% | 2022-09-08 | 2024-11-21 |
| CVE-2022-33082 | An issue in the AST parser (ast/compile.go) of Open Policy Agent v0.10.2 allows attackers to cause a Denial of Service (DoS) via a crafted input. | [email protected] | 7.5 | 1.43% | 2022-06-30 | 2024-11-21 |
| CVE-2022-28946 | An issue in the component ast/parser.go of Open Policy Agent v0.39.0 causes the application to incorrectly interpret every expression, causing a Denial of Service (DoS) via triggering out-of-range memory access. | [email protected] | 7.5 | 0.95% | 2022-05-19 | 2024-11-21 |
| CVE-2022-23628 | OPA is an open source, general-purpose policy engine. Under certain conditions, pretty-printing an abstract syntax tree (AST) that contains synthetic nodes could change the logic of some statements by reordering array literals. Example of policies impacted are those that parse and compare web paths. **All of these** three conditions have to be met to create an adverse effect: 1. An AST of Rego had to be **created programmatically** such that it ends up containing terms without a location (such a | [email protected] | 6.3 | 1.01% | 2022-02-09 | 2024-11-21 |
| CVE-2021-43979 | Styra Open Policy Agent (OPA) Gatekeeper through 3.7.0 mishandles concurrency, sometimes resulting in incorrect access control. The data replication mechanism allows policies to access the Kubernetes cluster state. During data replication, OPA/Gatekeeper does not wait for the replication to finish before processing a request, which might cause inconsistencies between the replicated resources in OPA/Gatekeeper and the resources actually present in the cluster. Inconsistency can later be reflected | [email protected] | 5.3 | 0.91% | 2021-11-17 | 2024-11-21 |
