- Summary
- tomcat8 vulnerabilities
- Details
-
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)
It was discovered that the Tomcat number guess example application did not properly sanitize user-supplied input. An attacker could possibly use this issue to inject malicious scripts, resulting in cross-site scripting. (CVE-2026-50229)
It was discovered that Tomcat incorrectly evaluated rewrite valve conditions in certain configurations. An attacker could possibly use this issue to bypass rewrite rules, resulting in unauthorized access. (CVE-2026-53404)
It was discovered that Tomcat incorrectly omitted certain authorization information when logging the effective web.xml configuration. An attacker could possibly use this issue to hide authorization constraints, resulting in reduced auditability. (CVE-2026-55276)
