CVE-2006-1546: Apache Struts

High severity, CVSS 7.5. EPSS: 6.3% chance of exploitation in the next 30 days.

Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to bypass validation via a request with a 'org.apache.struts.taglib.html.Constants.CANCEL' parameter, which causes the action to be canceled but would not be detected from applications that do not use the isCancelled check.

Affected products

• Apache Struts: up to and including 1.2.8
