• Maven org.springframework.security:spring-security-core: >= 5.3.0, < 5.3.2 → fixed in 5.3.2 • Maven org.springframework.security:spring-security-core: >= 5.2.0, < 5.2.4 → fixed in 5.2.4 • Maven org.springframework.security:spring-security-core: >= 5.1.0, < 5.1.10 → fixed in 5.1.10 • Maven org.springframework.security:spring-security-core: >= 5.0.0, < 5.0.16 → fixed in 5.0.16 • Maven org.springframework.security:spring-security-core: < 4.2.16 → fixed in 4.2.16

Spring Security versions 5.3.x prior to 5.3.2, 5.2.x prior to 5.2.4, 5.1.x prior to 5.1.10, 5.0.x prior to 5.0.16 and 4.2.x prior to 4.2.16 use a fixed null initialization vector with CBC Mode in the implementation of the queryable text encryptor. A malicious user with access to the data that has been encrypted using such an encryptor may be able to derive the unencrypted values using a dictionary attack.
