Spring · 2026-04-21 · via Spring Security Advisories

Description

Spring Security Authorization Server Dynamic Client Registration endpoints perform insufficient validation of certain client metadata fields when explicitly enabled.

An attacker possessing a valid Initial Access Token can dynamically register a malicious client with crafted metadata. Depending on the metadata provided and the Authorization Server's configuration, this can lead to Stored Cross-Site Scripting (XSS), Privilege Escalation, or Server-Side Request Forgery (SSRF).

Affected Spring Products and Versions

Spring Security:

  • 7.0.0 - 7.0.4

Spring Authorization Server:

  • 1.3.0 - 1.3.10
  • 1.4.0 - 1.4.9
  • 1.5.0 - 1.5.6

Mitigation

Users of affected versions should upgrade to the corresponding fixed version.

Affected version(s) Fix version Availability
7.0.x 7.0.5 OSS
1.3.x 1.3.11 Commercial
1.4.x 1.4.10 Commercial
1.5.x 1.5.7 OSS
