CVE-2026-85290InvoicePlane: Log Injection via Unsanitized User Input in Cron Key Error Logging
Medium 5.3
In plain English
A medium-severity security flaw in InvoicePlane from InvoicePlane. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities).
Official description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane's Cron::recur() method writes an invalid cron key from the URL path directly to the application log without neutralizing CRLF characters. An unauthenticated requester can place forged log lines into the audit trail by supplying a crafted cron_key value. The injected entries can corrupt forensic records and interfere with log-based monitoring. This issue is fixed in version 1.7.2.
