Technical Analysis
Spring Micrometer Tracing versions 1.7.0, 1.6.0 to 1.6.6, 1.5.0 to 1.5.12, and 1.4.13 and earlier are vulnerable to a denial of service condition due to CWE-770: Allocation of Resources Without Limits or Throttling. The vulnerability arises when the application uses Micrometer Tracing with W3C baggage propagation in the Brave bridge, leading to unbounded object allocation during extraction of incoming baggage headers. This can exhaust system resources and cause service disruption.
Potential Impact
The vulnerability can cause denial of service by exhausting system resources through unbounded object allocation when processing incoming baggage headers. There is no impact on confidentiality or integrity. The CVSS score of 5.3 reflects a medium severity with network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability.
Mitigation Recommendations
No official patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting or validating incoming baggage headers to prevent unbounded resource allocation.
