Technical description

The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.1.23. This is due to the `PermissionManager::manage_permissions()` function being registered as a callback on WordPress core's `map_meta_cap` filter and unconditionally returning the always-true `'exist'` primitive for every capability check whenever the evaluated user ID is 1, without scoping this behavior to plugin-specific capabilities. This makes it possible for authenticated attackers whose account is user ID 1, even subscribers, to pass every WordPress capability check, including `manage_options`, `edit_plugins`, `edit_themes`, `promote_users`, and `update_core`, thereby elevating their privileges to administrator-equivalent power and achieving full site takeover, including remote code execution via the plugin and theme editors. Exploitation is only impactful when user ID 1 has been deliberately demoted to a lower-privilege role as a common administrator-account hardening practice; on default installations where user ID 1 retains the administrator role, no incremental privilege gain occurs.

——0October System provides the system module for October Content Management System. Versions prior to 3.7.17 and 4.2.21 have a vulnerability in the Twig sandbox security policy that allowed a chained bypass when `cms.safe_mode` is enabled. The Laravel session store was exposed to Twig with unrestricted method access, and raw SQL methods reachable through Eloquent's `__call` forwarding were not blocked across the full builder chain. When combined, a backend user with CMS markup editing access could read arbitrary database values via raw SQL expressions and write to the backend authentication session key, forging a backend session as another existing user. The scope of impact is narrow. Safe Mode is a niche feature, primarily used for demo installations and multi-tenant or shared-editor scenarios where untrusted users are deliberately granted access to the CMS markup editor. Standard production deployments do not enable Safe Mode, because under normal October CMS guidance backend access - including markup editing - is restricted to trusted administrators, and direct PHP injection through markup is already possible without Safe Mode in that configuration. This issue only affects sites that meet all of the following conditions: `cms.safe_mode` is enabled (a deliberate opt-in for demos or untrusted-editor scenarios; the site has at least one backend user with CMS markup editing access who is not intended to be trusted as a full administrator; and the site has at least one existing superuser account whose session the lower-privileged user can impersonate. The vulnerability has been patched in v3.7.17 and v4.2.21. The Laravel session store is now wrapped in a proxy that exposes only an explicit subset of read/write methods and rejects writes to reserved session key prefixes (`admin_auth`, `october_auth`, `login_*`, `_token`, and other framework internals). Raw SQL and subquery methods (`selectRaw`, `whereRaw`, `orderByRaw`, `joinSub`, and related) are now blocked on `Query\Builder`, `Eloquent\Builder`, and `Eloquent\Model` so the blocklist is consistent across the `__call` forwarding chain. All sites that enable `cms.safe_mode` are encouraged to upgrade to the latest patched version. A workaround is available. Restrict CMS markup editing access to fully trusted administrators only - the standard October CMS recommendation for any deployment. Note that disabling `cms.safe_mode` is not a workaround; Safe Mode is the boundary this issue affects, and disabling it removes the only sandbox between markup editors and the server.21h CVE-2026-907877.3 HIG

——0Parallels Desktop runs prl_disp_service as root. Local clients reach it on the world-writable socket /var/run/prl_disp_service.socket. PrlSrv_LoginLocal accepts peer credentials. No Parallels signature. No admin group. After login, PrlSrv_InstallAppliance lets you pick the appliance folder (sVmParentPath). The daemon unpacks with one string, tar -xf "%1" -C "%2", then Qt QProcess::splitCommand chops that string into words. A quote in the folder name closes early. The leftover text becomes extra tar flags. macOS tar --use-compress-program= runs the named program as root.6h CVE-2026-12518—
