"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1064 advisory.

    Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in
    Apache Commons FileUpload.

    This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from 2.0.0-M1 before 2.0.0-M4.

    Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the issue. (CVE-2025-48976)

    Allocation of Resources Without Limits or Throttling vulnerability in Apache Tomcat. This issue affects
    Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from 9.0.0.M1 through
    9.0.105. Users are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue.
    (CVE-2025-48988)

    Authentication Bypass Using an Alternate Path or Channel vulnerability in Apache Tomcat.  When using
    PreResources or PostResources mounted other than at the root of the web application, it was possible to
    access those resources via an unexpected path. That path was likely not to be protected by the same
    security constraints as the expected path, allowing those security constraints to be bypassed.

    This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from
    9.0.0.M1 through 9.0.105.

    Users are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue.
    (CVE-2025-49125)
