New research from Zero Day Initiative found that the actively exploited PeopleSoft vulnerability, CVE-2026-35273, actually encompasses three distinct vulnerabilities that attackers can chain together.

Chris Jacob, Field CISO at Securonix said this:
“The danger of vulnerabilities like CVE-2026-35273 is how easily they allow threat actors to abuse internal trust relationships, transforming a critical enterprise application into a springboard for a much broader attack.
Once an attacker compromises a server, the battleground shifts entirely. The priority must immediately pivot from blocking the initial exploit to tracking post-compromise behavior, specifically how attackers attempt to establish persistence, harvest sensitive data, move laterally, or misuse trusted system credentials.
Security teams cannot rely on patching or perimeter controls alone, especially when attackers can mask their presence behind authenticated, seemingly legitimate local sessions. True resilience requires continuous, unified visibility across identities, applications, and infrastructure. Organizations need behavioral analytics that evaluate the full context of an action over time, allowing operations teams to distinguish routine administrative tasks from anomalous activity. The critical question isn’t just whether a vulnerability was triggered, but whether the trailing activity signals a deeper compromise and how fast defenders can isolate it.
I would spend some time to read this and take the action that is needed in order to save yourself some heartache.
