security advisoryunauthorized accesscross site scriptingUbuntu Tomcat Important Security Flaws CVE-2026-43515 CVE-2026-50229
Several security issues were fixed in Tomcat.. ========================================================================== Ubuntu Security Notice USN-8551-1 July 15, 2026 tomcat8 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in Tomcat. Software Description: - tomcat8: Servlet and JSP engine Details: It was discovered that Tomcat incorrectly handled authorization when multiple method constraints defined the same HTTP method. A remote attacker could possibly use this issue to bypass authorization restrictions. (CVE-2026-43515) It was discovered that the Tomcat number guess example application did not properly sanitize user-supplied input. An attacker could possibly use this issue to inject malicious scripts, resulting in cross-site scripting. (CVE-2026-50229) It was discovered that Tomcat incorrectly evaluated rewrite valve conditions in certain configurations. An attacker could possibly use this issue to bypass rewrite rules, resulting in unauthorized access. (CVE-2026-53404) It was discovered that Tomcat incorrectly omitted certain authorization information when logging the effective web.xml configuration. An attacker could possibly use this issue to hide authorization constraints, resulting in reduced auditability. (CVE-2026-55276) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS libtomcat8-embed-java 8.5.39-1ubuntu1~18.04.3+esm6 Available with Ubuntu Pro libtomcat8-java 8.5.39-1ubuntu1~18.04.3+esm6 Available with Ubuntu Pro tomcat8-examples 8.5.39-1ubuntu1~18.04.3+esm6 Available with Ubuntu Pro Ubuntu 16.04 LTS libtomcat8-java 8.0.32-1ubuntu1.13+esm2 Available with Ubuntu Pro tomcat8-examples 8.0.32-1ubuntu1.13+esm2 Available with Ubuntu Pro In general, a standard system update will make all the necessary changes.

(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.

Description: This update for tomcat fixes the followingissues Update to Tomcat 9.0.118: - CVE-2026-41284: Unbounded read in WebDAV LOCK and PROPFIND handling (bsc#1265162). - CVE-2026-41293: HTTP/2 request headers not validated (bsc#1265163). - CVE-2026-42498: WebSocket authentication header exposure (bsc#1265165). - CVE-2026-43512: digest authenticator will authenticate any unknown user (bsc#1265145). - CVE-2026-43513: LockOutRealm treats user names as case-sensitive (bsc#1265166). - CVE-2026-43514: AJP secret compared in non-constant time (bsc#1265167). - CVE-2026-43515: Security constraints not correctly applied (bsc#1265168). Changes: * Catalina + Add: Enhance version.sh and version.bat to display APR, Tomcat Native, and OpenSSL version information (both APR and FFM implementations), along with version compatibility warnings and third-party library version information. (csutherl) + Code: Refactor generation of the remote user element in the access log to remove unnecessary code. (markt) + Fix: Fix a regression in the previous release that meant ?- could appear in the access log rather than ? when the query string was present but empty. (markt) + Fix: Failed precondition should make WebDAV DELETE fail. #982 submitted by Mahmoud Alarby. (remm) + Fix: Align the escaping in ExtendedAccessLogValve with the other AccessLogValve implementations. (markt) + Fix: 70000: fix duplication of special headers in the response after commit, following fix for 69967. (remm) + Fix: Correct the handling of URIs mapped to a security constraint that only specifies the special ** role for all authenticated users. Requests without authentication were receiving 403 responses rather than 401 responses. (markt) + Fix: Fix a race condition in StandardContext.getServletContext() that could cause the jakarta.servlet.context.tempdir attribute to be lost during a context reload. Make the context field volatile and use locking to ensure only one ApplicationContext instance is created. (dsoumis) + Fix: Update the Windows authentication (kerberos) documentation toreflect that both Java and Windows are removing / have removed support for RC4-HMAC. The guide now uses AES256-SHA1. (markt) + Fix: Add a new initialisation parameter for WebDAV, maxRequestBodySize which limits the size of a WebDAV request body for LOCK and PROPFIND. The default value is 4096 bytes. (markt) + Add: Add a new caseSensitive attribute to the LockOutRealm that controls the manner in which user names are treated when making locking decisions. The default is false, meaning user names are treated in a case insensitive manner. (markt) + Fix: Correct the handling of invalid users with DIGEST authentication. (markt) + Fix: Ensure RealmBase finds all matching extension based security constraints. (markt) * Coyote + Fix: Avoid various edge cases if Content-Length is set via setHeader(String,String) or addHeader(String,String) with an invalid value by always clearing the previous value whether the new value is valid or not and ignoring any invalid new value. (markt) + Code: Refactor the calculation of the real index in the HPACK dynamic header table implementation to reduce code duplication. (markt) + Fix: Fix various minor issues with some HTTP/2 stream error messages for HTTP/2. (markt) + Fix: Consistently reject URIs containing NULL bytes when normalizing. + Fix: Fix a few minor memory leaks on error paths reading TLS keys and certificates when using FFM. (markt) + Fix: Refactor clean-up after HTTP/2 headers have been processed to aid GC after a stream reset. (markt) + Fix: Align HTTP/2 trailer fields with HTTP/1.1 and filter out any fields not permitted in trailers. (markt) + Fix: Free private keys after use in FFM based connector configuration. + Fix: Correct an unlikely edge-case parsing bug in the HTTP/2 HPACK header decoding that could result in a valid header triggering an unexpected connection close. (markt) + Fix: Refactor HTTP/2 HPACK encoding so header field names are only converted to lower case once during the encoding process. (markt) + Fix: Refactor HTTP/2header field validation so it occurs earlier. Extend validation to check for disallowed characters as well as upper case characters. (markt) + Fix: Add TLS 1.3 groups added in OpenSSL 4.0. (remm) + Fix: Add validation that the HTTP/2 :scheme pseudo-header is consistent with the use (or not) of TLS. (markt) + Fix: Correct the validation of pseudo headers and CONNECT requests to align Tomcat's behaviour with RFC 9113, section 8.5. (markt) + Fix: Fix a potential integer overflow when allocating capacity from a connection level window update to individual HTTP/2 streams. Based on #996 by Mike Tingey Jr. (markt) + Fix: Switch AJP secret comparison to a constant time algorithm. (markt) * WebSocket + Fix: Fix the initial connection to a WebSocket end point where the connection is made via a proxy that requires DIGEST authentication. * Other + Fix: 69993: Update the URL to the CDDL 1.0 license. (markt) + Add: Add warning when OpenSSL binary is not found. (csutherl) + Add: Add check for Tomcat Native library, and log warning when it's not found to make it easier to see when it's not used by the suite. (csutherl) + Update: Update Byte Buddy to 1.18.8. (markt) + Update: Update Bouncy Castle to 1.84. (markt) + Update: Improvements to French translations. (remm) + Update: Improvements to Japanese translations provided by tak7iji.
