CVE-2026-70449— Apache Wicket: Path traversal in resource style/variation/locale

Quick assessment

Affected
Apache Software Foundation Apache Wicket
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Wicket是美国Apache基金会的一款Java Web应用开发框架。 Apache Wicket 8.18.0及之前版本、9.23.0及之前版本和10.10.0及之前版本存在路径遍历漏洞，该漏洞源于资源URL属性验证不当，locale、style和variation属性未经路径分隔符检查被拼接到资源查找路径，可能导致未经身份验证的远程攻击者读取Web应用程序文件，包括WEB-INF目录下的文件。

Vulnerability Title
Apache Wicket: Path traversal in resource style/variation/locale
Source: CVE Program / CVE List V5
Vulnerability Description
Improper validation of resource URL attributes in Apache Wicket allows an unauthenticated remote attacker to read files from the web application, including files under WEB-INF that the servlet container would not otherwise serve. The locale, style and variation attributes decoded from a package resource URL are spliced into the resource lookup path without being checked for path separators. The IPackageResourceGuard — whose rejection of .. is one of the two intended controls — is applied to the resource name before those attributes are appended, and WebApplicationPath rejects only paths literally beginning with WEB-INF/. Neither control ever inspects the attacker-controlled portion of the path. On servlet containers that normalize .. in ServletContext.getResource(), a crafted request therefore escapes the intended package directory. The set of readable files is limited to the file extensions permitted by the configured IPackageResourceGuard. The default SecurePackageResourceGuard permits only js, css, png, jpg, jpeg, gif, ico, cur, map, html, txt, swf, bmp, svg, avif, eot, ttf, woff and woff2, which excludes configuration formats. Applications that have added patterns to the guard, or replaced it with the blocklist-based PackageResourceGuard, can additionally disclose configuration files such as web.xml. Independently of the extension, the lookup performed before the guard runs acts as an existence oracle for arbitrary paths. This issue affects Apache Wicket 8.18.0 and before, 9.23.0 and before and 10.10.0 and before. Users are recommended to upgrade to version 8.19.0, 9.24.0 or 10.11.0, which fix the issue. Users of Apache Wicket 7.x or older, which are no longer supported, should upgrade to a supported version.
