Technical description

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.3.1 This is due to the plugin substituting a user's `display_name` into the composed page markup unfiltered and then running the whole result through `do_shortcode()` in `TheFrontend::replace_content()`. Because `display_name` is writable by any user on their own account through the core profile form, this makes it possible for authenticated attackers with Subscriber-level access and above to execute arbitrary shortcodes. Where the page is a users collection — an ordinary team or member-directory page — the shortcode runs in the request of every visitor, including unauthenticated ones. Requires a published page with a Kirki element whose dynamic content is bound to the `display_name` user field.

CVE-2026-57209—

—

———Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version 0.17.17, when Heimdall operates in proxy mode, it constructs the Forwarded HTTP header after executing the matched rule pipeline by inserting the incoming request's Host header value directly into the header string without sanitizing commas or semicolons. This allows an attacker to inject additional parameters into the Forwarded header, potentially spoofing IP addresses for upstream services. This issue has been patched in version 0.17.17.10h CVE-2026-1157303.1 LOW

———i18next-http-backend 4.0.2 contains an incomplete fix in interpolateUrl() that allows attackers to redirect translation requests by supplying an ns value starting with a slash. Attackers controlling the namespace value can form a protocol-relative URL in loadPath or addPath templates to load attacker-hosted translations, enabling UI content injection and cross-site scripting.10h CVE-2026-942634.8 MED

———The Advanced Custom Fields: Extended and Advanced Custom Fields: Extended PRO WordPress plugins from 0.9.2.4 to 0.9.2.7 do not consistently disable shortcode processing in the confirmation message of their front-end forms, allowing unauthenticated visitors to have arbitrary shortcodes executed server-side when they submit a form whose stored configuration does not carry the relevant setting.9h CVE-2026-1146555.9 MED

——5libmongocrypt builds requests to external key management services (AWS, Azure and GCP) by inserting values from key vault documents, KMS provider configuration and KMS responses into request lines, headers and signed request bodies without validating or encoding them for each context. A user with write access to the key vault collection can alter the structure of these requests, including adding members to request bodies and token claims that the library then signs with the application's credentials. This may result in key management operations being performed with parameters the application did not intend.1d CVE-2026-1145777.3 HIG
