Low risk4th percentile - higher than 4% of all known CVEs
Summary
Rapid7 Velociraptor before version 0.76.6 contains a YAML injection vulnerability. An attacker can supply a crafted ZIP file that, when applied by an analyst, executes arbitrary VQL code with full privileges.
Risk Assessment
An analyst applying the remapping file may unknowingly execute malicious code, leading to workstation compromise and potential data leakage.
Recommendation
Update Velociraptor to version 0.76.6 or later.

- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.

The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.

Original NVD description (English source)
A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker providing a crafted collection ZIP can leverage literal double quotes and newlines in the hostname to break out of the YAML quoted string and inject a new mount remapping entry. When an analyst applies the generated remapping file with --remap, arbitrary VQL executes on their machine with NullACLManager (all permissions granted, unsandboxed).
