CVE-2026-47882: CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Spring Spring Tools for Eclipse
CVE-2026-47882 is a high-severity vulnerability in Spring Tools for Eclipse versions 5.2.0 and earlier. It involves the use of a non-cryptographic pseudo-random number generator to create a shared secret for authenticating Spring Boot DevTools remote-restart uploads. This weak randomness source undermines the cryptographic strength of the secret, potentially allowing attackers to predict or reproduce it. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
Spring Tools for Eclipse, when enabling Spring Boot DevTools support for remote application targets, generates a shared secret to authenticate remote-restart uploads. This secret is generated using a cryptographically weak pseudo-random number generator (PRNG) instead of a secure source of randomness, classified under CWE-338. The affected versions include all versions up to and including 5.2.0. The vulnerability has a CVSS v3.1 score of 8.3, indicating high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is provided at this time.
Potential Impact
The use of a weak PRNG for generating authentication secrets can allow attackers with network access to predict or reproduce the shared secret used for authenticating DevTools remote-restart uploads. This could lead to unauthorized remote code execution or manipulation of the deployed application, impacting confidentiality, integrity, and availability of the affected systems.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling Spring Boot DevTools remote support or restricting network access to trusted environments to reduce exposure.
