This update for tomcat fixes the following issues Update to Tomcat 9.0.119. Security issues fixed: - CVE-2026-50229: improper neutralization of script-related HTML tags in the number guess example (bsc#1269791). - CVE-2026-53404: always-incorrect control flow implementation in the rewrite valve caused non-OR conditions to be skipped if the first condition in an OR chain matched (bsc#1269910). - CVE-2026-53434: error condition not handled when configuring CRLs for a FFM based connector (bsc#1269824). - CVE-2026-55276: always-incorrect control flow implementation caused special roles and empty authorization constraints to not be included when the effective web.xml was logged (bsc#1269909). - CVE-2026-55955: improper authentication allows a replay attack against the EncryptionInterceptor in the cluster component (bsc#1269908). - CVE-2026-55956: improper authorization leads to security constraints specified for the default servlet ignoring any method or method omission configured as part of the constraint (bsc#1269907). Other updates and bugfixes: - Tomcat 9.0.119 * Catalina + Add: Add support for literal '%' characters in access log output. Based on pull request #1002 by Fabian Hahn. (markt) + Fix: Prevent duplicate log messages when clustering JARs are not present on startup. (csutherl) + Code: Remove unnecessary code from the SSI processing engine that was duplicating some of the normalisation checks. (markt) + Fix: Cleaner handling of invalid SPNEGO tokens. (remm) + Fix: Avoid some NPEs in the Connector class on an uninitialize protocol. (remm) + Fix: Incorrect session average life calculation. (remm) + Fix: Improve robustness on using Pipeline.setBasic on a running pipeline. (remm) + Fix: Avoid any init parameter updates when conflicts are found for filters, similar to what is done for servlets, as required by the servlet specification. (remm) + Fix: Fix container event cleanups in some edge cases. (remm) + Fix: Check for last-modified header in ExpiresFilter when a servlet uses addDateHeader to avoid wrongly considering it has been set. (remm) + Fix: Fix hour unit used by ExpiresFilter. (remm) + Fix: Remove exception swallowing in DataSourceStore to align it with FileStore and avoid session loss on errors. (remm) + Fix: Add support for single-quote escaped literal as well as quoted literals in DateFormatCache. (schultz) + Fix: On JAAS logout, clear out role principals on the subject that were added on commit, as recommended by the JAAS specification. (remm) + Fix: MemoryRealm should not add a dummy role when none is specified in the configuration. (remm) + Fix: DataSourceUserDatabase should return a null principal on a non existing user. (remm) + Fix: Fix shared lock expiration in WebDAV. (remm) + Fix: Inaccurate session exipration statistics when using the persistent manager. (remm) + Fix: Skip BOM when serving files with UTF-32 encoding. (remm) + Fix: Mixup of WrapperListener and WrapperLifecycle elements in storeconfig. (remm) + Fix: Incorrect processing of modified users in DataSourceUserDatabase. (remm) + Update: Clarify behavior in the UserDatabase for user, role and group creation that it does not immediately override existing elements. Removal (or update) needs to be used instead. (remm) + Fix: 70049: Align the web application class loader with parent class loaders and swallow any errors caused by invalid paths when looking up resources and behave as if the resources were not found in that case. (markt) + Fix: Improve validation of Range and Content-Range parsers so invalid ranges trigger a 4xx response rather than a 500 response. Pull request #1012 provided by Sahana Surendra Bogar. (markt) + Fix: Fix connection leak in ProxyErrorReportValve. (remm) + Fix: When using the RewriteValve, %{SSL:HTTPS} now returns on or off rather than true or false to align with httpd. (markt) + Fix: Reset the encoding used for query string parameters between requests in case an application changed the encoding in a previous request. (markt) + Fix: When encoding URLs with the CsrfPreventionFilter, don't add the nonce to URLs that are known not to require it. (markt) + Fix: Fix CombinedRealm isAvailable, it allows authentication if at least one sub realm is available. (remm) + Fix: 70048: Correctly handle asynchronous requests in PersistentValve. (markt) + Fix: Improve the detection of cross-context dispatches when using a RequestDispatcher. (markt) + Fix: Fix various instances of double decoding of URL patterns configured either programmatically or in web.xml. (remm/markt) + Fix: Align the rewrite conditions ornext flag processing with mod_rewrite, which follows a purely sequential evaluation strategy. (remm) + Fix: Change the default for the useRedirect attribute of the ProxyErrorReportValve from true to false. (markt) + Add: Add support for the showReport attribute in JsonErrorReportValve and ProxyErrorReportValve. When set to false, detailed error information (message, description, stack trace) is suppressed from error responses. (dsoumis) + Fix: Avoid a NoClassDefFoundError at startup when catalina-tribes.jar is removed but catalina-ha.jar is present and the Cluster element is enabled in server.xml. Cluster digester rules are now fully conditional on both JARs being available. (dsoumis) + Fix: Fix a potential deadlock when copying resources using WebDAV. (markt) + Fix: Add jakarta., org.apache.catalina. and org.apache.tomcat.to the list of reserved prefixes for SSI variables and request attributes. (markt) + Fix: Missing URL decoding when processing addMapping on a Servlet registration. (remm) + Fix: The Timeout WebDAV header allows comma separated values (according to the examples in the RFC). Use the first acceptable value. (remm) + Fix: Fix various issues when logging the effective web.xml for a web application. Empty sections are no longer logged. Special roles and empty authorisation constraints are included. (markt) + Fix: Expand the write lock for the save process in the MemoryUserDatabase to avoid concurrency issues with the file save operations. (markt) + Fix: Ensure atomic session persistence in FileStore. Based on pull request #1016 by sahvx655-wq. (markt) + Fix: Do not ignore methods configured on security constraints that map to the default servlet. (markt) * Cluster + Fix: Expand wording and increase visibility of log message when cloud membership is configured without a trust store as all certificates will be trusted in this configuration. (markt) + Fix: Ensure listeners are correctly added and removed when configuring the channel coordinator. (markt) + Fix: Fix some concurrency issues in FragmentationInterceptor. (markt) + Fix: Fix some concurrency issues in OrderInterceptor. (markt) + Fix: Fix some concurrency issues in TwoPhaseCommitInterceptor. (markt) + Fix: Fix concurrency issues generating MD5 digests in the CloudMembershipProvider implementations. (markt) + Add: Add replay protection to the EncryptInterceptor. This is a breaking change for the EncryptInterceptor. (markt) * Coyote + Add: Log a suitable warning if an encrypted PEM file is detected using an insecure form for encryption. (markt) + Fix: If TLS groups have been configured, use the configured groups rather than using OpenSSL's default TLS groups when using Tomcat Native with OpenSSL based connectors. (markt) + Fix: For HTTP/2, ensure that any in progress request body reads are cancelled if the container resets the a
