title: RedShield’s Service Proactively Protects from Critical React Server Components Vulnerability (“React2Shell” - CVE-2025-55182)
description: "RedShield has proactively deployed protection from the Critical React Server Components vulnerability “React2Shell” (CVE-2025-55182) for its customers.
Given the criticality of this vulnerability, RedShield conducted an emergency deployment of new attack signatures as baseline new signatures for all customer applications.  The new signatures were first placed in transparent (non-blocking) mode for monitoring, and RedShield subsequently determined that it was safe to put them into blocking mode.
RedShield’s application of the attack signatures in blocking mode mitigates this issue for customers of its application security service.  However, attack signatures are compensating controls and it is still important that customer teams identify impacted applications and apply vendor patches (see information below, including a link to React’s page with more details)."
