CVE-2026-57995

SUMMARY

phpMyFAQ before 4.1.5 contains a privilege escalation vulnerability in GroupController::updatePermissions that allows GROUP_EDIT administrators to grant arbitrary rights to groups without verifying they hold those rights themselves. A delegated administrator can exploit this by assigning high-value permissions to a group they belong to, inheriting those rights and escalating privileges up to full administrative control.

CVE-2026-56777

SUMMARY

n8n before 2.25.7 and 2.26.x before 2.26.2 contains an abstract syntax tree (AST) security validator bypass in the Python Code node. An authenticated user with permission to create or modify workflows containing a Python Code node can bypass the validator and access the task executor module namespace. The issue only affects self-hosted instances where the Python Task Runner is enabled; where N8N_BLOCK_RUNNER_ENV_ACCESS is configured to allow it, this can disclose environment variables accessible to the task runner process.

CVE-2026-56700

SUMMARY

Grav CMS before 2.0.0-beta.2 contains multiple code-execution vulnerabilities. Three unsafe unserialize() calls - in Scheduler\JobQueue, Framework\Cache\Adapter\FileCache, and Session - deserialize untrusted data without restricting allowed classes, enabling PHP object injection and, via a gadget chain, arbitrary code execution where an attacker controls the serialized input. Additionally, InstallCommand's git clone operation passes the branch, url, and path parameters into a shell command without escaping, allowing OS command injection via plugin/theme installation (which requires admin access). A Twig security blocklist bypass (server-side template injection) is also present. The issues are fixed in 2.0.0-beta.2.
