CVE-2026-41849: CWE-190: Integer Overflow or Wraparound in Spring Spring Framework
CVE-2026-41849 is an integer overflow vulnerability in the Spring Expression Language (SpEL) evaluation logic within Spring Framework versions 5. 3. 0 through 5. 3. 48. This flaw allows an attacker to supply a crafted SpEL expression that causes excessive resource consumption, leading to a denial of service (DoS) condition. The vulnerability has a high severity rating with a CVSS score of 7. 5. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
An integer overflow or wraparound exists in the evaluation logic of Spring Expression Language (SpEL) in Spring Framework versions 5.3.0 through 5.3.48. This vulnerability (CWE-190) can be triggered by an attacker supplying a specially crafted SpEL expression, which causes excessive resource consumption and results in a denial of service (DoS). The CVSS 3.1 base score is 7.5, reflecting a network attack vector with no privileges or user interaction required, and an impact limited to availability.
Potential Impact
Successful exploitation results in denial of service due to excessive resource consumption triggered by the integer overflow in SpEL evaluation. There is no impact on confidentiality or integrity reported. No known active exploits have been observed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider applying input validation or limiting the complexity of SpEL expressions if possible to reduce risk. Monitor vendor channels for updates and apply patches promptly once available.
