Description
This security bulletin contains information about 3 vulnerabilities.
1) Improper Resource Shutdown or Release (CVE-ID: CVE-2026-22740)
CWE-ID: CWE-404 - Improper Resource Shutdown or Release
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to improper resource management in multipart request handling in WebFlux when processing multipart requests. A remote user can send a series of multipart requests to consume available disk space.
Temp files created for parts larger than 10 K may remain undeleted after request processing under some circumstances.
2) Acceptance of Extraneous Untrusted Data With Trusted Data (CVE-ID: CVE-2026-22741)
CWE-ID: CWE-349 - Acceptance of Extraneous Untrusted Data With Trusted Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper cache control in static resource resolution when handling malicious requests for encoded resources. A remote attacker can send malicious requests to cause a denial of service.
Exploitation requires resource chain support with caching enabled, encoded resource resolution enabled, and an empty resource cache.
3) Resource exhaustion (CVE-ID: CVE-2026-22745)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in static resource handling when resolving static resources from the file system on Windows platforms. A remote attacker can send malicious requests that are slow to resolve to cause a denial of service.
The issue affects applications using Spring MVC or Spring WebFlux that serve static resources from the file system on Windows platforms.
