From version 0.38.0 through 0.70.5, FieldRepresentation.get_field_default inserts schema-controlled string, UUID, bytes, and fixed field defaults into quoted literals in generated Python source without escaping them. A crafted default can terminate the literal and inject statements into the generated module, which execute when the module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":60,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":221024,"id":"CVE-2026-108375","ts":1792027012059,"field":"exploit_available","old":"false","new":"true"}]}
