Adobe Priority Rating System
The Adobe Priority Rating System is a guideline to help customers in managed environments prioritize Adobe security updates. Adobe bases priority rankings on historical attack patterns for the relevant product, the type of vulnerability, the platform(s) affected, and any potential mitigations that are in place.
| Rating | Description |
| Priority 1 | This update resolves vulnerabilities being targeted, or which have a higher risk of being targeted, by exploit(s) in the wild for a given product version and platform. Adobe recommends administrators install the update as soon as possible (for example, within 72 hours). |
| Priority 2 | This update resolves vulnerabilities in a product that has historically been at elevated risk. There are currently no known exploits. Based on previous experience, Adobe does not anticipate exploits are imminent. As a best practice, Adobe recommends administrators install the update soon (for example, within 30 days). |
| Priority 3 | This update resolves vulnerabilities in a product that has historically not been a target for attackers. Adobe recommends administrators install the update at their discretion. |
