662-670: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winCache the loop-invariant permission state.
updateDocuments()can process batches of 1,000 documents. The permission validator has no count limit, and$permissionscan occupy up to 1,000,000 bytes. For each non-skipped document, the loop rescans the same$updatespermission list for all fourDatabase::PERMISSIONStypes and repeats the column regex work. Each document also performs a_permsSELECT, so this redundant CPU work adds to the existing per-document SQL cost.Compute
$initialonce before the loop. Compute$desiredonce after the skip guard, and reuse it for the remaining documents. Lazy computation preserves the current behavior when every document skips permission updates.♻️ Proposed refactor

- Around line 192-219: Apply the existing Validator\Key validation when creating
Attribute keys, ensuring keys exceeding the 36-character limit are rejected
before Adapter::filter() or permission creation. Update the attribute-creation
path and preserve the existing MariaDB and SQLite permission index definitions;
the cited MariaDB.php lines 192-219 and SQLite.php lines 424 and 444 require no
direct change because the root-cause fix is input validation.
- Around line 192-219: Add per-adapter migrations for existing _perms tables
before column-permission reads or writes are enabled. Update the MariaDB,
PostgreSQL, and SQLite migration flows to add _column as NOT NULL with a default
empty string, backfill legacy rows, and rebuild the unique _index1 to include
_column while preserving tenant handling and existing data.
In `@src/Database/Database.php`:
- Line 9093: Update the find() query-column authorization flow to always pass
PERMISSION_READ to assertColumnsQueryable, rather than the mutation-specific
$forPermission. Keep $forPermission available for row-level permission checks,
while filtering, ordering, and selecting use the caller’s read-column grants.
- Around line 7147-7149: Update updateDocuments to group documents by their
effective per-document payload, including any restored hidden $permissions in
each $new, rather than passing one shared $updates payload to
Adapter::updateDocuments. Invoke the adapter once for each group so every
document receives its own effective permissions while preserving the existing
assertColumnsWritable validation.

9393-9393: 🔒 Security & Privacy | 🛡️ Analyzed with Security Review | 🟠 Major | ⚡ Quick winAuthorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-863 — Incorrect AuthorizationFix:
find()'s fallback branch gates query columns on the wrong permission type.
assertColumnsQueryablemust always check READ, because filters and ordering read column values regardless of which row-level operation the call is for.count()andsum()both call it with no third argument (defaulting to READ), and the column-security branch just above (line 9384) hardcodesself::PERMISSION_READ. Only this fallback branch passes$forPermissionthrough.
updateDocuments()callsfind(..., forPermission: Database::PERMISSION_UPDATE)anddeleteDocuments()calls it withPERMISSION_DELETE. When a role holds a column-scoped UPDATE or DELETE grant that differs from its READ grant, this lets the caller filter or order on a column it cannot read, using match count oronNextresults as an oracle for that column's value.This mirrors a concern raised and marked addressed on an earlier commit of this PR; the fix did not carry over into this new fallback branch.
🛡️ Proposed fix
- $this->assertColumnsQueryable($collection, $queries, $forPermission); + // Filters, orders, and selects read column values, so the read grant + // governs them independently of the row-level permission this call is for. + $this->assertColumnsQueryable($collection, $queries);<security_verification_receipt>
<validation_method>static_trace</validation_method>
high
<confidence_rationale>Complete call chain is visible in this file: updateDocuments()/deleteDocuments() pass forPermission=UPDATE/DELETE into find(), which forwards it unchanged into assertColumnsQueryable in the fallback branch, while the sibling count()/sum() and the adjacent columnSecurity branch all correctly hardcode/default to READ, confirming the intended contract and isolating this as a regression at a single call site.</confidence_rationale>
