CVE-2026-33646

CRITICAL9.6

Published 2026-06-26 · Updated 2026-06-26 · Source security-advisories@github.com

Description

mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.3.10, mise processes .tool-versions files through the Tera template engine during parsing, with the exec() function registered, enabling arbitrary command execution. Unlike .mise.toml files, .tool-versions files are not subject to trust verification in non-paranoid mode. This means an attacker can place a malicious .tool-versions file in a git repository, and when a victim with mise activated cds into the directory, arbitrary commands execute without any trust prompt. This vulnerability is fixed in 2026.3.10.

CVE-2026-12415
The Invoice Generator plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the pravel_invoice_edit_account() AJAX action in versions up to, and including, 1.0.0. The handler is exposed via wp_ajax_nopriv_pravel_invoice_edit_account, accepts an attacker-controlled user_id and user_email from POST data, and calls wp_update_user() without verifying authentication, ownership, or a nonce. This makes it possible for unauthenticated attackers to change the email address of any user, including administrators, and then trigger WordPress's password reset flow to gain access to the targeted account.

CVE-2026-53576
Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, the authentication filter for the REST API (@Filter("/api/v1/**")) treats any request whose path ends in /configs as the public instance-config endpoint and forwards it without a credential check. kestra addresses its resources by URL path segments that the caller chooses (/api/v1/{tenant}/flows/{namespace}, /api/v1/{tenant}/executions/{namespace}/{id}, /api/v1/{tenant}/namespaces/{namespace}/kv/{key}). An anonymous caller picks the literal configs as the final segment, and the request bypasses Basic-Auth entirely. Because the bypass reaches the flow-create and execution-trigger routes, an unauthenticated caller creates a flow containing a Shell or Process task and runs it. The task executes as root inside the kestra container. The official docker-compose.yml mounts /var/run/docker.sock, so root in the container reaches the host Docker daemon. This vulnerability is fixed in 1.0.45 and 1.3.21.

CVE-2026-49869
Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, AuthenticationFilter in Kestra OSS uses request.getPath().endsWith("/configs") to whitelist the public configuration endpoint from Basic Auth. Because the check is a suffix match rather than an exact path match, any API path whose last segment is configs bypasses authentication entirely. An unauthenticated remote attacker can exploit this to create and execute arbitrary workflows without credentials. Because Kestra ships with script execution plugins (plugin-script-shell, plugin-script-python, etc.) enabled by default, this directly results in unauthenticated Remote Code Execution as root inside the Kestra worker container. This vulnerability is fixed in 1.0.45 and 1.3.21.

CVE-2026-54352
Budibase is an open-source low-code platform. Prior to 3.39.9, `POST /api/pwa/process-zip` at packages/server/src/api/routes/static.ts:24 accepts a builder-uploaded .zip, extracts it with extract-zip@2.0.1 into a temp directory, then for each entry listed in icons.json validates the icon path, opens it, and streams the bytes into MinIO. The resulting object is served back via GET /api/assets/{appId}/pwa/{uuid}.png. extract-zip@2.0.1 preserves absolute symlink targets when restoring symlink entries. The icon-source validator at packages/server/src/api/controllers/static/index.ts:259-268 resolves the icon source string against baseDir (path.resolve), checks resolvedSrc.startsWith(baseDir + path.sep) against that string, and calls fs.existsSync(resolvedSrc) which follows symbolic links to confirm the target exists. None of the three calls reject symbolic-link entries. packages/backend-core/src/objectStore/objectStore.ts:302 then calls (await fsp.open(path)).createReadStream() on the resolved path. fsp.open follows the symlink, the target file's bytes stream into MinIO, and the response of the asset-fetch endpoint returns those bytes verbatim. Result: a workspace-level builder reads any file the server process can open. This vulnerability is fixed in 3.39.9.
