• Apache Struts2 Core Arbitrary Code Execution via OGNL Sandbox Escape November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description Apache Struts2 Core version 7.4.0 and below attempt to prevent arbitrary code execution via Object-Graph Navigation Language (OGNL) through several different mechanisms but only in a cursory fashion -- the libraries only guard against immediate calls evaluated by the OGNL engine via `SecurityMemberAccess`, but an allowed […]
• Apache Struts2 Core TokenHelper Token Cryptographic Timing Side-Channel November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description The Apache Struts2 Core 7.4.0 and below performs session token comparisons cryptographically insecure early-exit comparison functions (e.g., `!=`, `memcmp`, byte-by-byte loops with `break`) that return as soon as the first mismatched byte is encountered. The execution time of the comparison is therefore proportional to the number […]
• Apache Struts2 Spring Plugin Uses a Previously Closed Resource November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description The Apache Struts2 Spring Plugin opens a Spring `ApplicationContex` via a try-with-resources block and, outside of said block, then continues to use the closed resource, resulting in an uncaught `IllegalStateException`. This particular issue prevents proper functionality and indicates poor code quality and code review standards and […]
• Apache Struts2 Core Integer Overflow November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description Apache Struts2 Core version 7.4.0 and below fails to properly prevent integer overflows, causing wrap-arounds and other issues on a downstream forced casting into types smaller than `BigInteger`. Importantly, this finding underscores why all applications using Struts and other such platforms should perform their own input […]
• Apache Struts2 Core Cross-Origin Protection Exemption Miskeyed to a Deployment-Wide Path November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description Apache Struts2 Core version 7.4.0 and below's `FetchMetadataInterceptor`, `CoepInterceptor`, and `CoopInterceptor` each compare their `exemptedPaths` configuration -- a per-interceptor-reference, administrator-supplied set of paths intended to exempt specific actions from the corresponding cross-origin protection -- against `HttpServletRequest.getContextPath()`. `getContextPath()` is fixed for the entire deployed web...
• Apache Struts2 REST Plugin Fails to Properly Parse Chunked Requests November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description The Apache Struts2 REST Plugin's (version 7.4.0 and below) `ContentTypeInterceptor.intercept(ActionInvocation)` only deserialises a request body and enforces the `struts.rest.content.maxLength` bound when `HttpServletRequest#getContentLength()` returns a positive value. `getContentLength()` returns `-1` whenever the `Content-Length` header is absent, which normal and appropriate for any Hypertext Transfer Protocol (HTTP)...
• Apache Struts2 REST Plugin Untrimmed `Accept` Header Tokens Break Content Negation Fallback November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01Description The Apache Struts2 REST Plugin's `DefaultContentTypeHandlerManager.getHandlerForResponse(HttpServletRequest, HttpServletResponse)` splits the `Accept` header on commas and passes each resulting token directly to `findHandler(String)` without trimming leading or trailing whitespace. `findHandler(String)` only retries a trimmed lookup when a token contains a semicolon (`;`), so a token that merely carries […]
• Apache Struts2 JSON Plugin Insecure Deserialisation -- Object Deserialisation Element-Count Limit Bypass November 2, 2026
  Posted by Daniel Owens via Fulldisclosure on Nov 01As of the current versions of the Apache Struts2 JSON Plugin (e.g., version 7.4.0 and the 7.5.0 snapshot dated 28 October 2026), attackers can bypass the element-count limit purported to protect Object deserialisation added to said code as part of the WW-5618 and S2-072 "hardening controls". Please […]
