Описание
Hibernate Validator before 6.2.0 and 7.0.0, by default and depending how it is used, may interpolate user-supplied input in a constraint violation message with Expression Language. This could allow an attacker to access sensitive information or execute arbitrary Java code. Hibernate Validator as of 6.2.0 and 7.0.0 no longer interpolates custom constraint violation messages with Expression Language and strongly recommends not allowing user-supplied input in constraint violation messages. CVE-2020-5245 and CVE-2025-4428 are examples of related, downstream vulnerabilities involving Expression Language intepolation of user-supplied data.
A flaw was found in Hibernate Validator. This vulnerability allows unauthorized access to sensitive information or the execution of arbitrary Java code by interpolating user-supplied input in a constraint violation message with an Expression Language.
Отчет
This vulnerability marked as Important rather than Moderate because it enables Expression Language (EL) injection through user-supplied input embedded in validation messages — effectively escalating a benign validation failure into a potential Remote Code Execution (RCE) vector. In environments where EL expressions have access to application internals, attackers can craft payloads that access sensitive Java objects, invoke arbitrary methods, or manipulate server-side logic. The fact that this behavior is triggered by the default configuration — without any explicit developer error — further amplifies the risk.
Меры по смягчению последствий
Users who are unable to upgrade should manually disable Expression Language interpolation to prevent EL injection. If disabling is not feasible, carefully sanitize and validate any dynamic input before inclusion.
