Description
This security bulletin contains information about 3 vulnerabilities.
1) Improper Authentication (CVE-ID: CVE-2026-43512)
CWE-ID: CWE-287 - Improper Authentication
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to authenticate as an unknown user.
The vulnerability exists due to improper authentication in the DIGEST authenticator when processing authentication for users not known to the configured Realm. A remote attacker can submit the password "null" for an unknown user to authenticate as an unknown user.
This occurs only when DIGEST authentication is configured.
2) Input validation error (CVE-ID: CVE-2026-41293)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to trigger unexpected application behavior.
The vulnerability exists due to improper input validation in HTTP/2 request header handling when exposing header values through the Servlet API. A remote attacker can send crafted HTTP/2 request headers to trigger unexpected application behavior.
This may affect applications that assume header values exposed through the Servlet API are specification compliant.
3) Improper access control (CVE-ID: CVE-2026-43515)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to bypass security constraints.
The vulnerability exists due to improper access control in HTTP method constraint processing when evaluating multiple security constraints for the same extension pattern. A remote attacker can send a request using an improperly constrained HTTP method to bypass security constraints.
