CVE-2025-61795: Apache Tomcat: Delayed cleaning of multi-part upload temporary files may lead to DoS

Improper Resource Shutdown or Release vulnerability in Apache Tomcat. If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.

Security readout for executives and security teams

CVE-2025-61795 can let authenticated users exhaust disk space on affected Apache Tomcat servers by triggering multipart upload errors. Failed uploads may leave temporary files behind until Java garbage collection removes them. Under load, disk use can grow faster than cleanup, causing service disruption. Exposure is most relevant for internet or internal applications running affected Tomcat versions that accept multipart uploads. Affected ranges are 11.0.0-M1 through 11.0.11, 10.1.0-M1 through 10.1.46, 9.0.0.M1 through 9.0.109, and known EOL 8.5.0 through 8.5.100. Treat as a timely availability fix, not an emergency breach event. Prioritize business-critical Tomcat applications with file upload features, especially externally reachable services and systems running unsupported 8.5 releases. Mitigation focus: Upgrade Tomcat to 11.0.12 or later, 10.1.47 or later, or 9.0.110 or later.; Move EOL Tomcat 8.5 deployments to a supported fixed release line.; Check Apache and product-vendor advisories for embedded Tomcat remediation guidance..
