CVE-2024-36401: in the CISA KEV catalogue

OSGeo GeoServer GeoTools Eval Injection Vulnerability. CISA added CVE-2024-36401 to the Known Exploited Vulnerabilities catalogue on 2024-07-15 with a default due date of 2024-08-05. Known ransomware campaign use: Unknown. Forensic triage flag: No.

OSGeo GeoServer GeoTools contains an improper neutralization of directives in dynamically evaluated code vulnerability due to unsafely evaluating property names as XPath expressions. This allows unauthenticated attackers to conduct remote code execution via specially crafted input. (CISA description)

Vendor / product: OSGeo GeoServer
CWE: CWE-95
CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
EPSS: 100%, percentile 99 (scored 2026-11-03)

EPSS puts nearly every time in 100 odds (100%) on exploitation activity being observed in the next 30 days. Its score is higher than or equal to that of 99% of scored CVEs. This is a model estimate about exploitation anywhere, not about your environment.
