Priority: This week (action score 72/100)
- CISA has confirmed exploitation in the wild (May 24, 2022). Remediation deadline for US federal agencies: Jun 14, 2022.
- Probability of exploitation in the next 30 days: 22.3% (FIRST EPSS); higher than 97.6% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
