This high-severity CVE scores 8.3 under NVD CVSS v3. EPSS exploit probability: 1.6% (75th percentile of EPSS-scored CVEs). 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).

Avo is an open source ruby on rails admin panel creation framework. The polymorphic field type stores the classes to operate on when updating a record with user input, and does not validate them in the back end. This can lead to unexpected behavior, remote code execution, or application crashes when viewing a manipulated record. This issue has been addressed in commit ec117882d which is expected to be included in subsequent releases. Users are advised to limit access to untrusted users until a new release is made.
