CISA added CVE-2026-102764 to its exploited list yesterday. Self-hosted Remote Support up to 26.2.3 is affected, and SaaS was patched on 9 Oct. The worrying part is the timeline: Mandiant and Google's threat intelligence group say exploitation began on 29 Aug, about six weeks before a fix (SecurityWeek). My list so far is apply the patch, look for unknown PHP files, rotate credentials the appliance could reach, and review session logs back to late August. I'm also auditing which remote-support and admin consoles we expose at all. This CTEM explainer frames the "confirm the exposure actually went down" step well. For anyone who has done a post-patch hunt on BeyondTrust, what turned up, and how far back did you go?

BeyondTrust Remote Support contains an authentication bypass by spoofing vulnerability that could allow a remote attacker to perform file operations on the appliance.

A memory-corruption vulnerability exists in a kernel-mode component of BeyondTrust Endpoint Privilege Management (Windows deployments) prior to version 26.1.2. Insufficient validation of input processed by the component may result in memory being accessed outside its intended bounds.

A vulnerability exists in the interaction between a Endpoint Privilege Management (Windows Deployment) support utility and the agent's tamper protection controls. Under certain conditions, the protections applied to the utility process may not be enforced as intended.

A high-severity vulnerability exists in a web application component of BeyondTrust Remote Support and Privileged Remote Access related to the processing of certain input parameters. Insufficient validation of user-supplied input may allow an authenticated attacker with limited privileges to access unintended resources or data beyond their authorization scope. Exploitation is restricted to accounts with specific permissions.

BeyondTrust Remote Support and Privileged Remote Access contain a high-severity pre-authentication vulnerability in the network communication subsystem. Insufficient validation of client-supplied input may allow an unauthenticated remote attacker to trigger a denial-of-service condition affecting appliance availability.

A critical pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support. Improper processing of authentication requests may allow an unauthenticated remote attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges. Exploitation requires a specific authentication configuration to be enabled.

A critical pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support and Privileged Remote Access. Improper validation of authentication data may allow a network-positioned attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges. Exploitation requires a specific authentication configuration to be enabled

BeyondTrust Remote Support (RS) and certain older versions of Privileged Remote Access (PRA) contain a critical pre-authentication remote code execution vulnerability. By sending specially crafted requests, an unauthenticated remote attacker may be able to execute operating system commands in the context of the site user.

Prior to 25.4.270.0, when wmic.exe is elevated with a full admin token the user can stop the Defendpoint service, bypassing anti-tamper protections. Once the service is disabled, the malicious user can add themselves to Administrators group and run any process with elevated permissions.

A medium severity vulnerability in BIPS has been identified where an authenticated attacker with high privileges can access the SSH private keys via an information leak in the server response.

A low severity vulnerability in BIPS has been identified where an attacker with high privileges or a compromised high privilege account can overwrite Read-Only smart rules via a specially crafted API request.

Prior to 23.1, an information disclosure vulnerability exists within BeyondInsight which can allow an attacker to enumerate usernames.

Prior to 23.2, it is possible to perform arbitrary Server-Side requests via HTTP-based connectors within BeyondInsight, resulting in a server-side request forgery vulnerability.

Improper Privilege Management vulnerability in BeyondTrust U-Series Appliance on Windows, 64 bit (local appliance api modules) allows Privilege Escalation.This issue affects U-Series Appliance: from 3.4 before 4.0.3.

Improper Privilege Management vulnerability in BeyondTrust U-Series Appliance on Windows, 64 bit (filesystem modules) allows DLL Side-Loading.This issue affects U-Series Appliance: from 3.4 before 4.0.3.

An issue was discovered in BeyondTrust Privilege Management for Windows before 24.1. When an low-privileged user initiates a repair, there is an attack vector through which the user is able to execute any program with elevated privileges.

Prior to version 24.1, a local authenticated attacker can view Sysvol when Privilege Management for Windows is configured to use a GPO policy. This allows them to view the policy and potentially find configuration issues.

A vulnerability has been discovered in Privileged Remote Access (PRA) and Remote Support (RS) which can allow an attacker with existing administrative privileges to inject commands and run as a site user.

A critical vulnerability has been discovered in Privileged Remote Access (PRA) and Remote Support (RS) products which can allow an unauthenticated attacker to inject commands that are run as a site user.

A heap-based buffer overflow was found in the way sudo parses command line arguments.

As per the researcher this vulnerability:

- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);

- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.

This could lead to privilege escalation.

BeyondTrust Privilege Management for Windows and Mac (aka PMWM; formerly Avecto Defendpoint) 5.1 through 5.5 before 5.5 SR1 mishandles command-line arguments with PowerShell .ps1 file extensions present, leading to a DefendpointService.exe crash.

The chat feature within Remote Support (RS) and Privileged Remote Access (PRA) is vulnerable to a Server-Side Template Injection vulnerability which can lead to remote code execution.

CVE-2026-1731: Command injection vulnerability in BeyondTrust Remote Support and Privileged Remote Access allows unauthenticated remote code execution

A medium-severity vulnerability has been identified in BeyondTrust Privilege Management for Windows versions <=25.7. Under certain conditions, a local authenticated user with elevated privileges may be able to bypass the product’s anti-tamper protections, which could allow access to protected application components and the ability to modify product configuration.

BeyondTrust Privileged Remote Access (PRA) versions prior to 25.1 are vulnerable to a local authentication bypass. A local authenticated attacker can view the connection details of a ShellJump session that was initiated with external tools, allowing unauthorized access to connected sessions.
