Descripción técnica

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.47.3 through 0.70.5, FieldRepresentation.get_field_default inserts a schema-controlled referenced record name into the callable position of a generated default_factory lambda without validating it as an Avro name. A crafted record name can become an arbitrary Python expression that executes when an instance of the generated model consumes the field default. Version 0.70.6 fixes the vulnerability by rejecting record names that do not match the Avro name grammar.

——0DedeCMS through 5.8.1-beta contains a PHP code injection vulnerability in ShowMsg() where the HTTP Referer header is written into a DedeTemplate string and included. Unauthenticated attackers can send a crafted Referer to /plus/flink.php?dopost=save with an empty validate code to execute arbitrary PHP and system commands. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.23h CVE-2026-1032344.8 MED

——3The WP Ultimate Review WordPress plugin before 2.4.5 does not neutralise shortcodes in all of the review fields submitted through its public review form, which is available to unauthenticated visitors, allowing them to execute arbitrary shortcodes when the affected field is displayed, provided user reviews and that field's display are enabled.19h CVE-2026-762937.2 ALT

——8In Splunk Enterprise versions below 10.4.3, 10.2.8, 10.0.11, and 9.4.16, a user that holds a role with the edit_manager_xml capability could execute arbitrary operating-system commands using the permissions of the user account running Splunk Enterprise by opening the affected configuration in the Splunk Web Manager page. The vulnerability is possible because Splunk Web evaluates user-controlled expressions from Manager XML without sufficiently restricting the expression syntax.20h CVE-2026-922078.8 ALT

——16MindsDB OpenBBtable Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of MindsDB. Authentication is required to exploit this vulnerability. The specific flaw exists within the OpenBBtable class. The issue results from the lack of proper validation of a user-supplied string before using it to execute Python code. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-28388.2d CVE-2026-114126—

——12Storybook is a frontend workshop for building user interface components and pages in isolation. From 8.0.0 until 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6, the Storybook development server can expose its WebSocket authentication token to clients able to load its HTML pages over a local network. A LAN attacker can obtain the token and invoke WebSocket-backed file-writing or testing functionality. Weak story-write validation can allow code to be placed in story files. If the Storybook Vitest addon is installed with an old version of Vitest, the payload can use a Vitest API to write additional files or execute commands. Depending on the payload and local tooling, the attack can lead to code execution with the developer's privileges. This issue is fixed in 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6.2d
