# CVE-2024-4879: ServiceNow Improper Input Validation Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-07-29, which means there is reliable evidence of exploitation in the wild.
