In HAProxy versions 2.6 through 3.3.5 a medium severity vulnerability CVE-2026-33555 was detected. This vulnerability allows attackers to cause desynchronization issues with the backend server by exploiting a flaw in the HTTP/3 parser, which fails to verify that the received body length matches the announced Content-Length when a stream is closed via an empty payload frame. This can be exploited for request smuggling, potentially leading to unauthorized access or cache poisoning. To address this issue users must upgrade to version 3.3.6 or other patched stable releases (2.6.25, 3.0.19, 3.2.15). For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-33555.

In Apache Kafka versions 4.1.0 and 4.1.1 a critical severity vulnerability CVE-2026-33557 was detected. This vulnerability allows attackers to bypass authentication and impersonate any user by providing an unvalidated JWT token, as the default validator fails to check signatures, issuers, or audiences. To address this issue users must upgrade to version 4.1.2, 4.2.0, or later, or explicitly set the validator class to BrokerJwtValidator.
