Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
AC:H reflects practical requirement to collect multiple ciphertexts and perform chosen-plaintext analysis; PR:L per described application interaction; C:H appropriate, I:N and A:N confirmed - no write or availability impact.

Applications using AesBytesEncryptor with the two-argument constructor or when passing a null IV generator and CBC as the encryption mode encrypt data with AES/CBC using a null (all-zero) initialization vector. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6 Spring Security 6.5.0 - 6.5.11 Spring Security 6.4.0 - 6.4.18 Spring Security 5.8.0 - 5.8.27 Spring Security 5.7.0 - 5.7.25
AnalysisAI
AES/CBC encryption in Spring Security's AesBytesEncryptor silently degrades to a null (all-zero) initialization vector when applications use the two-argument constructor or pass a null IV generator with CBC mode selected, completely undermining the semantic security of any data encrypted through this code path. Affected versions span Spring Security 5.7.0 through 7.1.0, covering multiple active release lines used extensively in Java and Spring Boot enterprise applications. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target application to instantiate AesBytesEncryptor using the two-argument constructor (e.g., new AesBytesEncryptor(password, salt)) or to explicitly pass a null IV generator with CBC mode - this is an API misuse pattern, not a default Spring Security configuration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) captures the network-accessible, low-privilege exploitation path and high confidentiality impact, but the AC:L rating likely understates practical attack effort: recovering plaintext via null-IV CBC analysis requires an attacker to collect multiple ciphertexts and apply chosen-plaintext techniques, imposing meaningful work beyond a single network request. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is upgrading to a patched Spring Security release; however, exact remediated version numbers are not specified in the provided intelligence data and must be confirmed directly from the vendor advisory at https://spring.io/security/cve-2026-47842. … Detailed patch versions, workarounds, and compensating controls in full report. |
