In June 2025, BeyondTrust mounted a high-severity RS/PRA Server-Facet Template Injection vulnerability that would additionally enable unauthenticated attackers to achieve distant code execution.
After publishing this story, BeyondTrust instructed BleepingComputer that there isn’t a recognized energetic exploitation of CVE-2026-1731 presently.
Earlier BeyondTrust flaws focused as zero-days
Whereas BeyondTrust says the CVE-2026-1731 vulnerability has not been focused within the wild, menace actors have exploited different BeyondTrust RS/PRA safety flaws in recent times.
