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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-470","CWE-20"],"references":["https://github.com/avo-hq/avo/commit/ec117882ddb1b519481bdd046dc3cfa4474e6e17","https://github.com/avo-hq/avo/security/advisories/GHSA-86h2-2g4g-29qx","https://github.com/avo-hq/avo/commit/ec117882ddb1b519481bdd046dc3cfa4474e6e17","https://github.com/avo-hq/avo/security/advisories/GHSA-86h2-2g4g-29qx"],"products":["avohq:avo"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-34102","score":0.0161,"percentile":0.7594,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-86h2-2g4g-29qx","url":"https://osv.dev/vulnerability/GHSA-86h2-2g4g-29qx","summary":"avo possible unsafe reflection / partial DoS vulnerability","modified":"2026-09-10T03:50:02.189348940Z","packages":[{"ecosystem":"RubyGems","name":"avo","purl":"pkg:gem/avo","ranges":["<2.33.3"],"fixed":["2.33.3"]},{"ecosystem":"RubyGems","name":"avo","purl":"pkg:gem/avo","ranges":[">=3.0.0.pre1 <=3.0.0.pre12"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
