CVE-2026-1731: Remote code execution vulnerability in BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA)

Noroxi assessment

Priority: Now (action score 97/100)

CISA has confirmed exploitation in the wild (Feb 13, 2026); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Feb 16, 2026.
A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
Probability of exploitation in the next 30 days: 93.8% (FIRST EPSS); higher than 99.8% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.
