  "details": "A record user with UPDATE access could read field values that field-level SELECT permissions hid from them. Arithmetic operators and `extend` embedded the raw operand into their error messages, and UPDATE permission checks evaluate against the unreduced document \u2014 so triggering such an error against a hidden field returned its value in the resulting error.\n\n### Impact\n\nA record user issues an UPDATE that performs an incompatible operation against a hidden field \u2014 e.g. `UPDATE person:me SET probe = email + 1` when `email` is a string \u2014 and reads the value from the returned error (`Tried to compute \"alice@example.com\" + 1 \u2026`). One field per operation, but the attacker can repeat against any field on any record they can UPDATE.\n\n### Patches\n\nA patch has been introduced that replaces the raw operand in every `try_*` operator and in `extend` with the operand\u0027s type name (`\"string\"`, `\"int\"`, `\"array\"`, etc.).\n\n- Versions 3.1.0 and later are not affected by this issue.\n\n### Workarounds\n\nAffected users who are unable to update should not grant UPDATE permission on records whose field-level SELECT permissions are expected to hide values from the same caller.",
