In Spring Framework versions 5.3.0 - 5.3.16, 5.2.0 - 5.2.19, and older unsupported versions, a vulnerability was identified where users could provide specially crafted SpEL (Spring Expression Language) expressions that may cause a denial of service condition. The vulnerability was assigned CVE-2022-22950 and was initially discovered and reported by security researcher 4ra1n (Spring Advisory, VMware Advisory).

The vulnerability has been assigned a CVSS v3.1 base score of 6.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The vulnerability is classified under CWE-770 (Allocation of Resources Without Limits or Throttling), indicating that the issue stems from improper resource management when processing SpEL expressions (NVD).

When successfully exploited, this vulnerability can lead to a denial of service condition, potentially affecting the availability of applications using the vulnerable versions of Spring Framework. The impact is limited to availability, with no direct effect on confidentiality or integrity of the system (NVD).

Users of affected versions should upgrade their Spring Framework installations to patched versions. Specifically, users of Spring Framework 5.3.x should upgrade to version 5.3.17 or later, while users of 5.2.x should upgrade to version 5.2.20 or later. No additional mitigation steps are necessary beyond the version upgrade (Spring Advisory).
