EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 83% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Sonatype Nexus Repository 3 did not properly filter internal configuration keys from user-supplied task properties when creating or updating a scheduled task through the administrative UI. An account holding permission to create at least one scheduled task type could supply a crafted property value that caused the system to overwrite the configuration of an unrelated, existing task instead of creating a new one.
