CVE-2026-0898

Estado: Pendiente de análisisCrítica (9)—

An arbitrary file-write vulnerability in Pega Browser Extension (PBE) affects Pega Robot Studio developers who are automating Google Chrome and Microsoft Edge using either version 22.1 or R25. This vulnerability does not affect Robot Runtime users. A bad actor could create a website that includes malicious code. The vulnerability may be exploited if a Pega Robot Studio developer is deceived into visiting this website during interrogation mode in Robot Studio.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
