CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in WebDAV LOCK and PROPFIND handling when processing request bodies. A remote attacker can send a large request body to cause a denial of service.

The affected requests are available to unauthenticated users.


2) Information disclosure (CVE-ID: CVE-2026-42498)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose authentication headers to a redirect target host.

The vulnerability exists due to exposure of sensitive information in Tomcat's WebSocket client when following a redirected WebSocket request after authentication. A remote user can trigger a redirect after authentication to disclose authentication headers to a redirect target host.

The issue occurs only if a WebSocket request is redirected after authentication.


3) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2026-43514)

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to disclose the AJP secret.

The vulnerability exists due to observable timing discrepancy in AJP secret comparison when validating the AJP secret. A remote attacker can perform a timing attack to disclose the AJP secret.

Exploitation is limited to an attacker on the local network.
