    CVE-2026-73180 (GCVE-0-2026-73180)

    Vulnerability from nvd – Published: 2026-08-25 22:01 – Updated: 2026-08-26 18:35
    VLAI
    Title
    Apache Tomcat: Authenticated WebSocket session survives end of HTTP session
    Summary
    Insufficient Session Expiration vulnerability in Apache Tomcat meant that if the session ID for an authenticated HTTP session was changed after a WebSocket connection had been established under that authenticated HTTP session, the WebSokcet session would not be closed as required by the Jakarta WebSocket specification when the HTTP session ended. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.43 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.

    Title
    Apache Tomcat: Limited replay attack possible with DIGEST authentication
    Summary
    Authentication Bypass by Capture-replay vulnerability in Apache Tomcat's DIGEST authenticator. If, before windowSize requests have been made, a client makes a DIGEST authenticated request with a nonceCount on the upper boundary of the replay window then that request is replayable once only while the associated nonceCount remains within the replay window.   This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.30 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.

    Title
    Apache Tomcat: Authenticated WebSocket session survives end of HTTP session
    Summary
    Insufficient Session Expiration vulnerability in Apache Tomcat meant that if the session ID for an authenticated HTTP session was changed after a WebSocket connection had been established under that authenticated HTTP session, the WebSokcet session would not be closed as required by the Jakarta WebSocket specification when the HTTP session ended. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.43 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.

    Title
    Apache Tomcat: Redirect after FORM auth may bypass method specific constraints
    Summary
    Incorrect Authorization vulnerability in Apache Tomcat's FORM authentication process allows the bypassing of a security constraint that limits user has access to a resource POST but not GET. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fixes the issue.

    Title
    Apache Tomcat: Limited replay attack possible with DIGEST authentication
    Summary
    Authentication Bypass by Capture-replay vulnerability in Apache Tomcat's DIGEST authenticator. If, before windowSize requests have been made, a client makes a DIGEST authenticated request with a nonceCount on the upper boundary of the replay window then that request is replayable once only while the associated nonceCount remains within the replay window.   This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.30 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.
