Package	Ecosystem	Affected	Fixed in

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Hibernate Validator versions before 6.2.0.CR1 and from 7.0.0.Alpha1 up to 7.0.0.CR1 (packages org.hibernate.validator:hibernate-validator and org.hibernate:hibernate-validator) may interpolate user-supplied input in constraint violation messages using Expression Language. Depending on how the library is used, an attacker who can supply such input could access sensitive information or execute arbitrary Java code. Upgrade to 6.2.0.CR1 or 7.0.0.CR1 or later, and avoid placing user-supplied input in constraint violation messages.
