In June 2025, BeyondTrust mounted a high-severity RS/PRA Server-Facet Template Injection vulnerability that might additionally enable unauthenticated attackers to achieve distant code execution.
Earlier BeyondTrust flaws focused as zero-days
Whereas the corporate has but to say whether or not attackers have exploited the just lately patched CVE-2026-1731 vulnerability within the wild, different BeyondTrust RS/PRA security flaws have been focused in recent times.
