CVE Severity Published▾ Status Exploitation Description
CVE-2025-15104 Medium 2026-01-16 No exploit published Proof of concept only Nu Html Checker (validator.nu) contains a restriction bypass that allows remote attackers to make the server perform arbitrary HTTP/HTTPS requests to internal resources, including localhost services. While the validator implements hostname-based protections to block direct access to localhost and 127.0.0.1, these controls can be bypassed using DNS rebinding techniques or domains that resolve to loopback addresses.This issue affects The Nu Html Checker (vnu): latest (commit 23f090a11bab8d0d4e698f1ffc197a4fe226a9cd).
CVE-2025-35036 Medium 2025-06-03 No exploit published Proof of concept only 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.
CVE-2023-1932 Medium 2024-11-07 No exploit published No public exploit A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.
CVE-2020-10693 Medium 2020-05-06 No exploit published No public exploit A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.
CVE-2019-10219 Medium 2019-11-08 Protected by Waratek No public exploit A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.
CVE-2014-3558 Medium 2014-09-30 No exploit published No public exploit ReflectionHelper (org.hibernate.validator.util.ReflectionHelper) in Hibernate Validator 4.1.0 before 4.2.1, 4.3.x before 4.3.2, and 5.x before 5.1.2 allows attackers to bypass Java Security Manager (JSM) restrictions and execute restricted reflection calls via a crafted application.
