Apache StreamPark <2.1.7: Weak AES-ECB Encryption Exposes JWT
CVE-2025-54981 Published on December 12, 2025
Apache StreamPark: Weak Encryption Algorithm in StreamPark
Weak Encryption Algorithm in StreamPark, The use of an AES cipher in ECB mode and a weak random number generator for encrypting sensitive data, including JWT tokens, may have risked exposing sensitive authentication data
This issue affects Apache StreamPark: from 2.0.0 before 2.1.7.
Users are recommended to upgrade to version 2.1.7, which fixes the issue.
Vulnerability Analysis
CVE-2025-54981 can be exploited with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Use of a Broken or Risky Cryptographic Algorithm
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information. The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.
