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-2025-66372	Low	2025-11-28	Protected by Waratek	No public exploit	Mustang before 2.16.3 allows exfiltrating files via XXE attacks.
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-2024-46984	Critical	2024-09-19	Protected by Waratek	No public exploit	The reference validator is a tool to perform advanced validation of FHIR resources for TI applications and interoperability standards. The profile location routine in the referencevalidator commons package is vulnerable to `XML External Entities` attack due to insecure defaults of the used Woodstox WstxInputFactory. A malicious XML resource can lead to network requests issued by referencevalidator and thus to a `Server Side Request Forgery` attack. The vulnerability impacts applications which use referencevalidator to process XML resources from untrusted sources. The problem has been patched with the 2.5.1 version of the referencevalidator. Users are strongly recommended to update to this version or a more recent one. A pre-processing or manual analysis of input XML resources on existence of DTD definitions or external entities can mitigate the problem.
CVE-2020-16164	High	2020-07-30	No exploit published	No public exploit	An issue was discovered in RIPE NCC RPKI Validator 3.x through 3.1-2020.07.06.14.28. It allows remote attackers to bypass intended access restrictions or to cause a denial of service on dependent routing systems by strategically withholding RPKI Route Origin Authorisation ".roa" files or X509 Certificate Revocation List files from the RPKI relying party's view. NOTE: some third parties may regard this as a preferred behavior, not a vulnerability
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-2017-7536	High	2018-01-10	Protected by Waratek	No public exploit	In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().
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.
