Summary
tomcat9, tomcat10 vulnerabilities
Details

It was discovered that Tomcat did not properly limit the size of WebDAV LOCK and PROPFIND request bodies. A remote attacker could use this issue to cause Tomcat to consume excessive memory, resulting in a denial of service. (CVE-2026-41284)

It was discovered that Tomcat incorrectly validated HTTP/2 header fields. A remote attacker could use this issue to cause Tomcat to crash or possibly execute arbitrary code. (CVE-2026-41293)

It was discovered that Tomcat did not properly clear HTTP authentication headers during WebSocket connection upgrades and redirects. A remote attacker could use this issue to obtain sensitive credentials. (CVE-2026-42498)

It was discovered that Tomcat incorrectly handled digest authentication. A remote attacker could possibly use this issue to bypass authentication restrictions. (CVE-2026-43512)

It was discovered that Tomcat incorrectly handled case sensitivity in LockOutRealm. A remote attacker could possibly use this issue to bypass account lockout protections and obtain sensitive information. (CVE-2026-43513)

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)
