CVE-2026-28811Hinoki check available

Unauthenticated information disclosure through debug messages

Published Jul 30, 2026 · Updated Jul 30, 2026

Information disclosure in Apache JSPWiki 2.12.3 and earlier allows remote attackers to read sensitive details in debug messages. Apache has not published the affected error-handling locus, the triggering request, or which internal details the debug messages expose. Network access without authentication or user interaction is sufficient; the disclosed impact is limited to confidentiality.
