CVE-2026-40975
Spring Boot Weak PRNG for Secrets
Overview
Description
Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} and ${random.long} should never be used for secrets as they are numeric values with a predictable range. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); random value property source / weak PRNG for secrets. Versions that are no longer supported are also affected per vendor advisory.

Solution
Update to a patched version for proper secret management and random value generation.
- Update Spring Boot to a fixed version.
- Avoid using numeric or predictable values for secrets.
- Use a strong cryptographically secure random number generator.
