Improper Authentication vulnerability in Apache Tomcat allowed a replay attack against the EncryptionInterceptor in the cluster component.

This issue affects Apache Tomcat: from 11.0.0 through 11.0.22, from 10.1.0 through 10.1.55, from 9.0.13 through 9.0.18, from 8.5.38 through 8.5.100, from 7.0.100 through 7.0.109.

Users are recommended to upgrade to version 11.0.23, 10.1.56, 9.0.119, which fixes the issue.

• CVE-2026-55955: add replay protection to the cluster EncryptInterceptor by encrypting a trusted timestamp with each message and rejecting duplicate, stale or future messages via the new replayWindowTime and replayWindowMessageCount attributes (upstream tomcat 9.0.119). The default encryptionAlgorithm also changes from AES/CBC/PKCS5Padding to AES/GCM/NoPadding, because the replay protection is only effective for non-malleable algorithms. NOTE: this changes the encrypted cluster message format, so a cluster using EncryptInterceptor must be restarted as a whole, not node by node

The updated packages fix security vulnerabilities: XSS in number guess example. (CVE-2026-50229) Bad ornext processing in RewriteValve. (CVE-2026-53404) Invalid CRL configuration doesn't trigger failure for FFM Connector. (CVE-2026-53434) Logged effective web.xml is incomplete. (CVE-2026-55276) EncryptInterceptor not protected against replay attacks. (CVE-2026-55955) Security constraints for default servlet ignored method. (CVE-2026-55956) Authentication bypass with JNDIRealm and GSSAPI authenticated bind. (CVE-2026-55957)

These are all security issues fixed in the tomcat11-11.0.23-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the tomcat-9.0.119-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the tomcat10-10.1.56-1.1 package on the GA media of openSUSE Tumbleweed.

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-2026-53434: 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).
