Processing such a request can cause that record to be looked up without the usual ownership or scoping restrictions, then updated and linked to the requesting user's own record. This may result in unintended disclosure and unauthorized modification of data belonging to other users of the application.\n\n## Affected\n\n- `mongoid >= 8.0.0, < 8.0.12`\n- `mongoid >= 8.1.0, < 8.1.13`\n- `mongoid >= 9.0.0, < 9.0.12`\n- `mongoid = 9.1.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `mongoid 9.0.12`\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-29 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93758.json)","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
