Red Hat advises disabling the $data feature in ajv if it is not required by the application. If $data must be used, implement strict validation of input fields referenced by the pattern keyword to ensure only expected and safe characters are allowed. Users should follow the vendor guidance to mitigate risk.
Description
CVE-2025-69873 is a vulnerability in the ajv library used by Red Hat Lightspeed in Satellite. When the $data option is enabled, an attacker can supply a malicious regular expression pattern that triggers a Regular Expression Denial of Service (ReDoS), causing high CPU consumption and application unresponsiveness. The vulnerability requires the $data feature to be enabled and attacker ability to send crafted input. The flaw is rated with important severity due to its potential to cause denial of service with relatively small payloads.
