Technical description

LeRobot through 0.5.1 contains an unsafe deserialization vulnerability in the async inference pipeline where pickle.loads() is used to deserialize data received over unauthenticated gRPC channels without TLS in the policy server and robot client components. An unauthenticated network-reachable attacker can achieve arbitrary code execution on the server or client by sending a crafted pickle payload through the SendPolicyInstructions, SendObservations, or GetActions gRPC calls.

——14The Prime Mover – Backup and Migration plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.2.1 via deserialization of untrusted input in the migration search-and-replace routine (recursiveUnserializeReplace()). An unauthenticated attacker can store a crafted, base64-encoded serialized object in wp_comments.comment_content through the standard comment-submission endpoint (wp-comments-post.php). When an administrator subsequently performs a routine Prime Mover export or restore, the plugin base64-decodes that stored value and passes it to unserialize() with no allowed_classes restriction. A Property-Oriented Programming (POP) chain is present in the plugin's own bundled Freemius library (FS_Clone_Manager::__set → FS_Option_Manager::set_option → store() → update_option()), so no additional plugin or theme is required — the plugin ships the gadget itself.2d CVE-2026-578458.8 HIG

——14Hugging Face Datasets through 5.1.0 contains an insecure deserialization vulnerability that allows attackers to execute arbitrary Python code by crafting a malicious pickle file loaded through the deprecated pandas packaged builder. Attackers can supply a pickle-backed dataset that is processed by Pandas._generate_tables via pandas.read_pickle() without validation, so when a victim calls datasets.load_dataset("pandas", data_files=...), the embedded __reduce__ payload executes code with the victim process's privileges.2d CVE-2026-1146247.2 HIG

——15baserCMS is a website development framework. In versions 5.0.0 before 5.3.2 and 5.4.0 before 5.4.2, the widget-area entity serializes widgets only when the submitted value is an array, allowing a string submitted through the admin JSON API to be stored unchanged. Entity reads, including front-end rendering and API responses, deserialize the stored value with unserialize() without an allowed_classes restriction, accepting both raw and base64-encoded serialized data. An administrator, or an attacker who obtains widget-write capability through a separate vulnerability such as chained XSS, can plant an object graph that subsequently triggers on unauthenticated page requests. Two demonstrated gadget chains in the default dependency set use composer/composer ProcessExecutor::startJob() with Process::fromShellCommandline(), or logiscape/mcp-sdk-php StdioTransport::connect() with StdioServerParameters, to reach proc_open() and execute commands as the web-server user. Deserialization bypasses constructor-based readonly safeguards, and the stored payload can execute repeatedly until the database row is repaired. Unauthenticated page access is a trigger after privileged payload storage, not an unauthenticated means of initially planting the payload. This issue has been patched in versions 5.3.2 and 5.4.2.2d
