EPSS estimates a 1.2% probability of exploitation in the next 30 days.
It can be exploited remotely over the network.
What to do
CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see… (federal deadline 2026-10-19)
Check your inventory against the 5 affected products — start with internet-facing systems.
Until patched, restrict network exposure of affected systems and watch for exploitation attempts.
The vulnerability exists within internal components of BeyondTrust’s Remote Support product. The components did not adequately validate the origin of the messages it received. Under the right conditions, this could allow an attacker to perform file operations on the appliance.

Direct intelligence-source lanes: every lane below has direct evidence for
in that Scantide intelligence collection. Lanes share the CVE as their join key; their presence together does not imply that one source explicitly referenced another source's record.
These vendors are derived from affected product/device evidence tied to this CVE. This is intentionally separate from the direct intelligence-source lanes above: a vendor can have affected products without Scantide having a vendor-specific advisory or Microsoft KB record for the CVE.

These CVEs are connected because CISA published them in the same advisory. This is strong contextual correlation, but does not by itself mean they form an exploit chain.

Vulnerability summary: Improper Origin Validation in Internal Messaging Components of BeyondTrust Remote Support
The vulnerability exists within internal components of BeyondTrust’s Remote Support product. The components did not adequately validate the origin of the messages it received. Under the right conditions, this could allow an attacker to perform file operations on the appliance.
Only sources that directly identify or describe the queried CVE are shown here. Historical examples from MITRE CWE definitions are kept in the weakness section and are not presented as related CVEs.
Affected-product scope: The product/device count is the deduplicated set Scantide can prove from its currently ingested structured records and advisory text. It is not a claim that only those products were affected; component vulnerabilities such as Log4Shell can have a much larger downstream ecosystem. Advisory and vendor references are kept clickable so additional downstream exposure can be followed to the authoritative source.
Coverage note: Scantide correlates multiple public and locally indexed intelligence sources, but no dataset or matching process is complete. Results may omit software, dependencies, affected versions or advisories, and related records do not by themselves prove that a specific installation is vulnerable. Confirm important findings against vendor guidance and the installed product and version.
