- Summary
- Fix CVE(s): CVE-2026-59083
- Details
-
- SECURITY UPDATE: Security constraint bypass in the RewriteValve - the
decoded and normalized request URI used for subsequent security
constraint matching was produced with java.net.URLDecoder.decode(),
which applies form-encoding rules and converts '+' to a space instead
of performing proper URI percent-decoding
- debian/patches/CVE-2026-59083.patch: use Tomcat's UDecoder.URLDecode() (already imported and used elsewhere in the class) instead of java.net.URLDecoder.decode() to build the decoded request URI
