CVE-2025-64775 High 2025-12-01 No exploit published No public exploit Denial of Service vulnerability in Apache Struts, file leak in multipart request processing causes disk exhaustion. This issue affects Apache Struts: from 2.0.0 through 6.7.0, from 7.0.0 through 7.0.3. Users are recommended to upgrade to version 6.8.0 or 7.1.1, which fixes the issue.
CVE-2023-41835 High 2023-12-05 No exploit published No public exploit When a Multipart request is performed but some of the fields exceed the maxStringLength  limit, the upload files will remain in struts.multipart.saveDir  even if the request has been denied.

CVE-2023-49735 High 2023-11-30 Protected by Waratek No public exploit ** UNSUPPORTED WHEN ASSIGNED ** The value set as the DefaultLocaleResolver.LOCALE_KEY attribute on the session was not validated while resolving XML definition files, leading to possible path traversal and eventually SSRF/XXE when passing user-controlled data to this key. Passing user-controlled data to this key may be relatively common, as it was also used like that to set the language in the 'tiles-test' application shipped with Tiles. This issue affects Apache Tiles from version 2 onwards. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2023-34396 High 2023-06-14 No exploit published No public exploit Allocation of Resources Without Limits or Throttling vulnerability in Apache Software Foundation Apache Struts.This issue affects Apache Struts: through 2.5.30, through 6.1.2. Upgrade to Struts 2.5.31 or 6.1.2.1 or greater
CVE-2018-1327 High 2018-03-27 Protected by Waratek No public exploit The Apache Struts REST Plugin is using XStream library which is vulnerable and allow perform a DoS attack when using a malicious request with specially crafted XML payload.

CVE-2016-3090 High 2017-10-30 No exploit published No public exploit The TextParseUtil.translateVariables method in Apache Struts 2.x before 2.3.20 allows remote attackers to execute arbitrary code via a crafted OGNL expression with ANTLR tooling.
CVE-2016-4461 High 2017-10-16 No exploit published No public exploit Apache Struts 2.x before 2.3.29 allows remote attackers to execute arbitrary code via a "%{}" sequence in a tag attribute, aka forced double OGNL evaluation. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-0785.
CVE-2017-9804 High 2017-09-20 No exploit published No public exploit In Apache Struts 2.3.7 through 2.3.33 and 2.5 through 2.5.12, if an application allows entering a URL in a form field and built-in URLValidator is used, it is possible to prepare a special URL which will be used to overload server process when performing validation of the URL.

CVE-2016-1181 High 2016-07-04 Protected by Waratek No public exploit ActionServlet.java in Apache Struts 1 1.x through 1.3.10 mishandles multithreaded access to an ActionForm instance, which allows remote attackers to execute arbitrary code or cause a denial of service (unexpected memory access) via a multipart request, a related issue to CVE-2015-0899.
CVE-2015-0899 High 2016-07-04 Protected by Waratek No public exploit The MultiPageValidator implementation in Apache Struts 1 1.1 through 1.3.10 allows remote attackers to bypass intended access restrictions via a modified page parameter.
CVE-2016-0785 High 2016-04-12 No exploit published No public exploit Apache Struts 2.x before 2.3.28 allows remote attackers to execute arbitrary code via a "%{}" sequence in a tag attribute, aka forced double OGNL evaluation.
