Summary
In the MISP sachertortephp library, the Xml::build() static method contains a logic error in the condition controlling network-based XML fetching. Due to operator precedence, the HTTPS branch is executed even when the readFile option is set to false, allowing an attacker to force outbound HTTPS requests to arbitrary URLs (SSRF).
Risk Assessment
The risk is potential unauthorized access to internal network resources or disclosure of information from external services. An attacker could exploit this to scan internal networks or read data from internal systems.
Recommendation
Correct the logic in Xml::build() so that the readFile option (when set to false) also disables HTTPS fetching. It is recommended to update to a patched version of the library or apply a workaround by validating input data.

The Security For WooCommerce WordPress plugin from 1.0.10 to 1.0.16 does not perform capability checks when creating users through an action available to unauthenticated visitors, and lets the caller choose the new account's role. This allows unauthenticated attackers to create administrator accounts and take over the site.

An OS command injection vulnerability was discovered in the Google Cloud DNS validation module of the OPNsense os-acme-client plugin through 4.17. The DnsGcloud::prepare() method decodes the dns_gcloud_key model field and directly interpolates the gcloud_account and gcloud_project string fields into a shell command passed to proc_open() via LeUtils::run_shell_command() without validation or escaping. A remote authenticated user with privileges to issue or renew certificates through the WebGUI/API can achieve arbitrary code execution as root.

Kyverno 1.18.0 before 1.19.2 contains a signature verification bypass in verifyImages because cached verification results are keyed by the image reference string (such as a tag) rather than bound to the verified digest, so cache hits skip signature and attestation checks. An attacker who can submit workloads and move a registry tag can warm the cache with a signed image, repoint the tag, and have Kyverno admit the workload and use mutateDigest to pin the unverified digest.

Kyverno from 1.17.0 before 1.19.2 contains a privilege escalation vulnerability that allows namespace-scoped tenants to modify resources in other namespaces through NamespacedMutatingPolicy targetMatchConstraints.expression CEL output lacking namespace checks. Attackers can emit a literal target such as another tenant's RoleBinding, which the cluster-wide background controller then mutates to add attacker subjects or alter Roles, NetworkPolicies, and ConfigMaps.
- CVE-2026-122311Critical
Kyverno from 1.16.0 before 1.19.2 fails to validate path segments in the resource argument of resource.get() and resource.post(), allowing namespaced CEL policies to escape their namespace. Tenants who can create a NamespacedValidatingPolicy can insert .. segments to read and write arbitrary cluster objects using the admission controller's ServiceAccount, leading to cluster takeover.

Kyverno from 1.19.1 before 1.19.2 validates a Policy's context.apiCall urlPath after cleaning it but executes the raw path, whose fragment or query the Kubernetes client discards. A namespace-scoped user who can create a Policy can hide ../ segments behind # or ? to reach cluster-scoped endpoints with Kyverno's ServiceAccount, gaining cluster admin.
- CVE-2026-122304Critical
Kyverno from 1.17.0 before 1.19.2 contains an authorization bypass vulnerability that allows namespace admins to escape namespace confinement because the cleanup controller builds its context loader with a nil policy. Attackers can create a namespaced CleanupPolicy with apiCall or globalReference context entries to read cross-namespace Secrets and modify validatingwebhookconfigurations using the cleanup controller's ServiceAccount.
- CVE-2026-122303Critical
Kyverno from 1.17.0 before 1.19.2 contains an authorization bypass vulnerability that allows namespace tenants to overwrite resources in other namespaces via NamespacedMutatingPolicy mutate-existing targetMatchConstraints.expression. Attackers can return a CEL map literal fabricating a target with an attacker-chosen metadata.namespace, causing the privileged background controller to overwrite Secrets, Deployments, or policies cluster-wide.
- CVE-2026-122302Critical
Kyverno before 1.19.2 contains a privilege escalation vulnerability that allows namespace admins to create resources beyond their RBAC because generate-rule admission checks verify the controller's permissions, not the author's. Attackers can create a namespaced Policy with generate rules targeting other namespaces or cluster-scoped kinds, making the background controller create or clone resources cluster-wide.
Original NVD description (English source)
In the MISP sachertortephp library, the Xml::build() static method in lib/Cake/Utility/Xml.php contains a logic error in the conditional that gates network-based XML fetching. The original condition was written as: $options['readFile'] && strpos($input, 'http://') === 0 || strpos($input, 'https://') === 0. Because PHP's && operator has higher precedence than ||, the expression is evaluated as ($options['readFile'] && strpos($input, 'http://') === 0) || strpos($input, 'https://') === 0. As a result, when a caller explicitly sets the readFile option to false to disable file and URL reading, an input string beginning with https:// still satisfies the condition and triggers a network fetch via HttpSocket (configured to follow up to 10 redirects). The http:// branch is correctly gated by the readFile flag, but the https:// branch is not. An attacker who can influence the $input parameter passed to Xml::build() can therefore force the application to issue an outbound HTTPS request to an attacker-controlled or internal URL, even though the caller intended to suppress all remote reads. The fetched response is parsed as XML and may be returned to the caller, enabling information disclosure from internal services or external targets. This constitutes a Server-Side Request Forgery (SSRF) weakness with an information-disclosure impact. The vulnerability requires that the code path in Xml::build() be reachable with attacker-controlled input and that the readFile option be set to false (or the caller expects it to be false).
