AI description

Automated description summarized from trusted sources.

CVE-2025-48976 is a denial-of-service (DoS) vulnerability affecting the Apache Commons FileUpload library. The vulnerability stems from insufficient limits on resource allocation for multipart headers. A remote attacker could exploit this vulnerability by sending a specially crafted request with an excessively large number of multipart headers. This can lead to uncontrolled memory consumption within applications using the library, potentially exhausting system resources and causing a denial of service. The issue affects Apache Commons FileUpload versions from 1.0 before 1.6, and from 2.0.0-M1 before 2.0.0-M4. Users are recommended to upgrade to versions 1.6 or 2.0.0-M4 to mitigate the vulnerability.
