Descripción técnica

The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 10.2.1 via deserialization of untrusted input . This makes it possible for authenticated attackers, with custom-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. This vulnerability is only exploitable during lesson creation when a temporary lesson ID triggers the custom metadata path, and requires the attacker to hold a role with the edit_course capability, such as Instructor, Instructor's Assistant, LMS Manager, or Administrator.

———Hugging 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.7h CVE-2026-1146247.2 ALT

———baserCMS 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 5.4.2.7h CVE-2026-1128599.8 CRÍ
