• Code: Remove unnecessary calls to String.intern() in the parsing of configuration files. (markt)
• Fix: Extend sessionAttributeValueClassNameFilter to include filtering of dynamic proxy interface classes. (markt)
• Fix: Attempt to use rollback when persisting user data to the DataSourceUserDatabase fails and improve error reporting. (remm)
• Fix: 70143: Handle InvalidFileNameException when parsing parts to rethrow it as an IllegalStateException as mandated by the Servlet specification. (remm)
• Fix: Add missing reason to the JsonErrorReportValve. (remm)
• Fix: evaluation of the N and C flags for rewrite rules. (remm)
• Fix: qsd flag should always discard the original query string when rewriting. (remm)
• Fix: Add appropriate escaping for context path, current directory name and parent directory name for directory listings produced by the default servlet. Ensure XML escaping is used with XML output. (markt)
• Fix: When processing certificate subject names and issuer names within RewriteValve rules, always use the RFC 2253 format name. (markt)
• Fix: the incorrect rejection of requests using digest authentication when the client provided nonce count is at the upper boundary of the window (markt).
• Update: Separate the Context role mapping from the Servlet specification security-role-ref. (remm)
• Fix: Handle the case where the JNDIRealm is configured to perform role searches with userRoleAttribute but the attribute is not available or not configured for the current user. (markt)
• Fix: Improve handling of session attribute addition concurrent with session expiration.

This attribute controls whether URLs and URL patterns provided in the deployment descriptor (web.xml), annotations and/or their programmatic equivalents are treated as being provided in URL-encoded form (i.e. using %nn encoding) or in decoded form. The Servlet specification requires that they are provided in decoded form. However, Tomcat has historically treated them as if they are provided in encoded form. In Tomcat 12, they will always be treated as if they are provided in decoded form. This setting enables migration from encoded form to decoded form on an application by application basis.

Changes for tomcat:

• Update to Tomcat 9.0.121

• Catalina

• Fix: Ensure that a login-config conflict when merging web.xml fragments triggers a deployment failure. (markt)
• Code: Remove unnecessary calls to String.intern() in the parsing of configuration files. (markt)
• Fix: Extend sessionAttributeValueClassNameFilter to include filtering of dynamic proxy interface classes. (markt)
• Fix: Attempt to use rollback when persisting user data to the DataSourceUserDatabase fails and improve error reporting. (remm)
• Fix: 70143: Handle InvalidFileNameException when parsing parts to rethrow it as an IllegalStateException as mandated by the Servlet specification. (remm)
• Fix: Add missing reason to the JsonErrorReportValve. (remm)
• Fix: evaluation of the N and C flags for rewrite rules. (remm)
• Fix: qsd flag should always discard the original query string when rewriting. (remm)
• Fix: Add appropriate escaping for context path, current directory name and parent directory name for directory listings produced by the default servlet. Ensure XML escaping is used with XML output. (markt)
• Fix: When processing certificate subject names and issuer names within RewriteValve rules, always use the RFC 2253 format name. (markt)
• Fix: the incorrect rejection of requests using digest authentication when the client provided nonce count is at the upper boundary of the window (markt).
• Update: Separate the Context role mapping from the Servlet specification security-role-ref. (remm)
• Fix: Handle the case where the JNDIRealm is configured to perform role searches with userRoleAttribute but the attribute is not available or not configured for the current user. (markt)
• Fix: Improve handling of session attribute addition concurrent with session expiration. An application will now either see a successful addition followed by expiration or the addition will not succeed. It is no longer possible for the session to expire and the addition to succeed. This is of particular not for attributes that implement HttpSessionBindingListener. (markt)
• Fix: Add a new attribute to the Context, urlPatternsProvidedInDecodedForm. This attribute controls whether URLs and URL patterns provided in the deployment descriptor (web.xml), annotations and/or their programmatic equivalents are treated as being provided in URL-encoded form (i.e. using %nn encoding) or in decoded form. The Servlet specification requires that they are provided in decoded form. However, Tomcat has historically treated them as if they are provided in encoded form. In Tomcat 12, they will always be treated as if they are provided in decoded form. This setting enables migration from encoded form to decoded form on an application by application basis. This attribute will be removed in Tomcat 12 where it…

• CVE-2026-68569: Principal lookup can fail open in some cases (bsc#1276900).
• CVE-2026-68763: DoS via allocation leak in HTTP/2 backlog tracking when a stream is reset (bsc#1276901).
• CVE-2026-73180: Authenticated WebSocket session survives end of HTTP session (bsc#1276902).

Changes for tomcat10:

• Update to Tomcat 10.1.59

• Catalina

• Fix: Ensure that a login-config conflict when merging web.xml fragments triggers a deployment failure. (markt)
• Code: Remove unnecessary calls to String.intern() in the parsing of configuration files. (markt)
• Fix: Extend sessionAttributeValueClassNameFilter to include filtering of dynamic proxy interface classes. (markt)
• Fix: Attempt to use rollback when persisting user data to the DataSourceUserDatabase fails and improve error reporting. (remm)
• Fix: 70143: Handle InvalidFileNameException when parsing parts to rethrow it as an IllegalStateException as mandated by the Servlet specification. (remm)
• Fix: Add missing reason to the JsonErrorReportValve. (remm)
• Fix: evaluation of the N and C flags for rewrite rules. (remm)
• Fix: qsd flag should always discard the original query string when rewriting. (remm)
• Fix: Add appropriate escaping for context path, current directory name and parent directory name for directory listings produced by the default servlet. Ensure XML escaping is used with XML output. (markt)
• Fix: When processing certificate subject names and issuer names within RewriteValve rules, always use the RFC 2253 format name. (markt)
• Fix: the incorrect rejection of requests using digest authentication when the client provided nonce count is at the upper boundary of the window (markt).
• Update: Separate the Context role mapping from the Servlet specification security-role-ref. (remm)
• Fix: Handle the case where the JNDIRealm is configured to perform role searches with userRoleAttribute but the attribute is not available or not configured for the current user. (markt)
• Fix: Improve handling of session attribute addition concurrent with session expiration. An application will now either see a successful addition followed by expiration or the addition will not succeed. It is no longer possible for the session to expire and the addition to succeed. This is of particular not for attributes that implement HttpSessionBindingListener. (markt)
• Fix: Add a new attribute to the Context, urlPatternsProvidedInDecodedForm. This attribute controls whether URLs and URL patterns provided in the deployment descriptor (web.xml), annotations and/or their programmatic equivalents are treated as being provided in URL-encoded form (i.e. using %nn encoding) or in decoded form. The Servlet specification requires that they are provided in decoded form. However, Tomcat has historically treated them as if they are provided in encoded form. In Tomcat 12, they will always be treated as if they are provided in decoded form. This setting enables migration from encoded form to decoded form on an application by application basis. This attribute will be removed in Tomcat 12…
