CVE-2026-85290Public exploitNetwork attack vectorHinoki check available

Audit-log forgery via unsanitized cron key

Published Sep 25, 2026 · Updated Sep 25, 2026

Log injection in InvoicePlane before 1.7.2 allows remote attackers to forge audit entries through a crafted cron key in the URL path. Cron::recur() concatenates an invalid user-supplied cron key into an error-level log message without neutralizing CRLF characters. The unauthenticated cron endpoint is sufficient to corrupt forensic records or interfere with log-based monitoring, without reported data disclosure or service interruption.
