Kyverno 1.16.0 through 1.19.0 registers the globalcontext.Lib CEL library in its policy environment without confining it to the policy's namespace, unlike the sibling libraries (resource.Lib, http.Lib, configMap loader) which are handed the policy namespace. A tenant who can create a namespaced policy (e.g. NamespacedValidatingPolicy, and likewise the namespaced mutating, deleting, generating, and…

Kyverno is a policy engine for Kubernetes. In versions 1.14.0 through 1.19.0, the ImageValidatingPolicy (policies.kyverno.io/v1beta1) evaluator never reads the spec.images and spec.allowedValues fields of a PolicyException. Any PolicyException whose policyRefs and matchConditions match a resource causes image signature verification to be skipped for the entire resource rather than only for the lis…

Kyverno before 1.19.1 contains a namespace isolation bypass in the apiCall context entry of namespaced Policy resources due to inconsistent path interpretation between validation and execution. A low-privilege tenant can use percent-encoded dot-segments in urlPath to bypass namespace checks and read resources from other namespaces using the Kyverno admission controller's ServiceAccount credentials…

Hugo versions from v0.162.0 before v0.166.0 contain a case-sensitive validation flaw in the security.http.urls IP-literal deny rule that allows attackers to bypass restrictions. Attackers can use mixed-case URL schemes in resources.GetRemote calls to fetch from restricted IP addresses like localhost.

Adminer 6.0.0 through 6.0.1, when the official ClickHouse driver plugin (plugins/drivers/clickhouse.php, rewritten in 6.0.0) is loaded, is vulnerable to pre-authentication server-side request forgery. An unauthenticated attacker can submit auth[driver]=clickhouse with auth[server] set to an arbitrary URL (for example http://127.0.0.1:18089), causing the Adminer server to issue an HTTP POST contain…

Budibase versions before 3.45.0 fail to validate per-app authorization in the POST /api/global/groups/:groupId/apps endpoint, allowing builders to assign application roles across workspace boundaries. A builder of a single workspace can exploit missing per-app authorization checks to grant themselves admin roles in other workspaces by modifying user group role mappings.

Hugo versions from v0.161.0 through v0.165.0 run Node.js tools (css.PostCSS, css.TailwindCSS, js.Babel) under the Node.js permission model to restrict file system reads to the project directory and configured mounts.

Hugo is a static site generator. In versions after v0.123.0 and before v0.166.0, Hugo's symlink confinement checks stopped at the mount root itself, so a theme or module checked into themes/ (or a vendored module) could contain a symlink at a mount root (for example themes/mytheme/assets -> /some/dir/outside). Files behind such a symlink were readable during a site build through resources.Get, res…

Budibase Server before 3.45.0 contains an arbitrary file write vulnerability in the PWA icon upload endpoint that extracts user-supplied ZIP archives without proper symlink validation. Attackers with BUILDER role can craft a malicious ZIP with leaf symlink entries followed by duplicate file entries to write arbitrary files as root, enabling remote code execution.

The access map is gated by a `security@: admin.super` guard that is resolved by the field's exact path, so a submitted flat dot-notation key such as `access.admin.super` (instead of the nested `access[admin][super]`) matches no blueprint rule, survives BlueprintSchema::filterArray() an…
