medium Tenable Self-Hosted Container Security Plugin ID 437320

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Grav is a file-based Web platform. Prior to 1.8.0-beta.27, A Denial of Service (DoS) vulnerability has
 been identified in Grav related to the handling of scheduled_at parameters. Specifically, the application
 fails to properly sanitize input for cron expressions. By manipulating the scheduled_at parameter with a
 malicious input, such as a single quote, the application admin panel becomes non-functional, causing
 significant disruptions to administrative operations. The only way to recover from this issue is to
 manually access the host server and modify the backup.yaml file to correct the corrupted cron expression.
 This vulnerability is fixed in 1.8.0-beta.27. (CVE-2025-66303)
