CVE-2026-85290: InvoicePlane log injection in Cron controller

CVE-2026-85290 · Severity: medium · CVSS 5.3 · Published 2026-09-25

InvoicePlane is a self-hosted invoicing application used to manage invoices, clients, and payments. An unauthenticated attacker can inject forged log entries by supplying a crafted cron key parameter, corrupting audit trails and interfering with log-based security monitoring. This does not grant direct access to business data but undermines the integrity of forensic records.

Technical details

The vulnerability is a log injection (CWE-117) in the Cron controller's recur() method, where the cron_key parameter from the URL is logged directly without sanitizing CRLF characters. An unauthenticated attacker can inject newline characters to fabricate fake log entries. The fix applies the existing sanitize_for_logging() helper function to neutralize the input before logging.
