CVE-2026-47882: CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Spring Spring Tools for Eclipse
When enabling Spring Boot DevTools support for a remote application target (for example a Docker container or Cloud Foundry app) from the Spring Tools Boot Dashboard, Spring Tools generates a shared secret that authenticates DevTools remote-restart uploads to the deployed application. This secret was generated using a non-cryptographic pseudo-random number generator rather than a cryptographically secure source of randomness. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier
AI Analysis
Technical Summary
Spring Tools for Eclipse versions 5.2.0 and earlier use a non-cryptographically secure pseudo-random number generator to create a shared secret that authenticates DevTools remote-restart uploads to deployed applications. This use of a weak PRNG (CWE-338) undermines the cryptographic strength of the secret, potentially allowing attackers to predict or reproduce the secret, leading to unauthorized access or manipulation of the remote restart process.
Potential Impact
The vulnerability impacts the confidentiality, integrity, and availability of the remote DevTools restart feature by allowing potential attackers to bypass authentication through prediction or reproduction of the shared secret. This could lead to unauthorized remote restarts or code uploads to deployed applications, compromising application stability and security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid enabling Spring Boot DevTools support for remote application targets or restrict access to trusted networks to reduce exposure.
