CVE-2026-92948
Description détaillée
vm2 versions >= 3.9.6 and <= 3.11.6 are affected by a NodeVM builtin allowlist bypass that permits a sandbox escape on Node.js 24 and newer when the embedder explicitly allows the node:test builtin (e.g. require: { builtin: ['node:test'] }). On Node.js 24+, module.builtinModules exposes the scheme-only key node:test, which is not covered by vm2's family-based DANGEROUS_BUILTINS protection, so it is stored in the generic host-passthrough loader. Because requireImpl() in lib/setup-node-sandbox.js strips a single 'node:' prefix before the builtin lookup, sandbox code calling require('node:node:test') resolves to the stored node:test key and receives a readonly proxy to the host module. Calls to node:test.run() are forwarded to the host implementation, which spawns a separate Node process for process-isolated test execution and passes through attacker-controlled execArgv values; supplying --eval=<JavaScript> therefore executes arbitrary JavaScript in an unrestricted host Node process outside the NodeVM sandbox. Fixed in vm2 3.11.7.

CVE-2026-93015
BlueKitchen BTstack through 1.8.2 fails to validate the peer-reported endpoint count against table bounds in A2DP stream endpoint discovery. A bonded peer can send an AVDTP DISCOVER response with more endpoints than the fixed table holds, causing out-of-bounds writes that corrupt adjacent static objects and crash the process or sever event delivery.
CVE-2026-93014
RosarioSIS versions before 12.9 fail to validate the filename request parameter in Users and Students modules, allowing authenticated users to unlink allow-listed files via path traversal. Attackers can use parent-directory sequences to escape upload directories and delete CSS, XML, JSON resources and other users' documents throughout the installation.
CVE-2026-93013
RAGFlow through 0.27.2 contains a path traversal vulnerability in the dev_insert_chunks_from_file and dev_insert_metadata_from_file endpoints that allows authenticated attackers to read arbitrary files by supplying absolute file paths in the file_path parameter. Attackers with valid access tokens can exploit missing path validation to read any file accessible to the service, with disclosure limited to files matching expected JSON structures that are then written to datasets.
