| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-104714 | High | 2026-10-05 | No exploit published | No public exploit | Concurrent execution using shared resource with improper synchronization ('race condition') vulnerability in Apache Struts. Where a localized message formats a date or time argument, the formatter retained for that message by the application-wide text provider is used by concurrently served requests without isolation, so a value belonging to one user can appear in another user's response, or the rendering can fail and surface as a server error. Applications whose localized messages format no date or time arguments are not affected. This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue. |
| CVE-2026-104712 | High | 2026-10-05 | No exploit published | No public exploit | Asymmetric resource consumption (amplification) vulnerability in Apache Struts. When a request parameter is bound to an arbitrary-precision decimal (java.math.BigDecimal) property that is then rendered through the Struts tag library, the framework can produce a response many orders of magnitude larger than the request, allowing an unauthenticated remote attacker to exhaust server CPU and outbound network capacity with sustained low-volume traffic. Applications that do not bind request parameters to BigDecimal properties, or never render such a property through the Struts tag library, are not affected. This issue affects Apache Struts: from 2.5.14 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue. |
| CVE-2026-73635 | High | 2026-08-15 | No exploit published | No public exploit | Allocation of resources without limits or throttling vulnerability in Apache Struts. When no fixed locale is configured, the locale used for localized-text lookups is taken from the incoming request, allowing an unauthenticated remote client to cause the framework's internal localized-text caches to grow without bound and exhaust the Java heap, denying service to other users. Applications that configure a fixed locale are not affected. This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1. Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue. |
| CVE-2026-73634 | High | 2026-08-15 | No exploit published | No public exploit | Uncontrolled resource consumption vulnerability in Apache Struts. An application that exposes an endpoint collecting Content Security Policy violation reports reads the submitted report into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. Such endpoints are ordinarily reachable without authentication. The core distribution maps no such endpoint by default; applications that do not collect violation reports are not affected. This issue affects Apache Struts: from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1. Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue. |
| CVE-2026-73633 | High | 2026-08-14 | No exploit published | No public exploit | Uncontrolled resource consumption vulnerability in the JSON plugin of Apache Struts. When an application is configured to populate actions from a JSON request body, the plugin reads that body into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. The plugin's configurable JSON input length limit does not bound this read. The JSON plugin is an optional component; applications that do not use it, or use it without enabling JSON request-body handling, are not affected. This issue affects Apache Struts: from 2.1.8 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1. Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue. |
| CVE-2025-66675 | High | 2025-12-10 | 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 6.7.4, 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. It's related to https://cve.org/CVERecord?id=CVE-2025-64775 - this CVE addresses missing affected version 6.7.4 |
| 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. Users are recommended to upgrade to versions Struts 2.5.32 or 6.1.2.2 or Struts 6.3.0.1 or greater, which fixe this issue. |
| 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. Upgrade to the Apache Struts version 2.5.16 and switch to an optional Jackson XML handler as described here http://struts.apache.org/plugins/rest/#custom-contenttypehandlers. Another option is to implement a custom XML handler based on the Jackson XML handler from the Apache Struts 2.5.16. |
