Tempo Operator, PrimeReact Vulnerabilities Disclosed

A query RBAC bypass vulnerability in the Tempo Operator could allow an attacker to gain unauthorized access to sensitive information or perform actions they are not permitted to. This flaw, tracked as CVE-2026-62147, affects the Tempo Operator component and could have significant security implications for systems relying on its access control mechanisms. Further details on the exploitability and impact are still emerging, but any bypass of RBAC controls warrants immediate attention and investigation by security teams. It is crucial to monitor for any available patches or mitigation strategies from the vendor.

In the PrimeReact component library, a vulnerability (CVE-2026-15538) has been identified that could permit a remote attacker to modify object prototype attributes. This type of vulnerability can lead to prototype pollution, potentially enabling attackers to execute arbitrary code, bypass security restrictions, or cause denial-of-service conditions. While the specific impact depends on how PrimeReact is implemented and used within an application, the ability to alter object prototypes remotely is a serious concern. Developers should exercise caution and review their usage of PrimeReact, applying any available updates or security best practices to mitigate the risk.
