Apache Camel has an incomplete fix for CVE-2025-27636

The fix for CVE-2025-27636 added setLowerCasetrue to HttpHeaderFilterStrategy so that case-variant header names such as 'CAmelExecCommandExecutable' are filtered out alongside 'CamelExecCommandExecutable'. The same setLowerCasetrue call was not applied to five non-HTTP HeaderFilterStrategy...

Heimdall: Case-sensitive host matching may lead to policy bypass

Summary Heimdall performs host matching in a case-sensitive manner, while HTTP hostnames are case-insensitive. This discrepancy can result in heimdall failing to match a rule for a request host that differs only in letter casing, potentially causing the request to be classified differently than...

Heimdall: Case-sensitive handling of URL-encoded slashes may lead to inconsistent path interpretation

Summary Heimdall handles URL-encoded slashes %2F in a case-sensitive manner, while percent-encoding is defined to be case-insensitive. As a result, the lowercase equivalent %2f is not recognized and therefore not processed as expected when allowencodedslashes is set to off the default setting. Th...
