"details" : "## Summary\n\n`MyAccountController::postAccountInfoForm` allows an authenticated user to update\nthe authentication column (default: `email`) without verifying their current password.\nBecause email is the account-recovery anchor, this enables account takeover after\nthe attacker's session ends: the new email address can be used to request a password\nreset from outside the system.\n\nThe password-change endpoint in the same controller correctly requires `old_password`\nverification, so the gap is asymmetric.\n\n## Details\n\nThe `postAccountInfoForm` action passes `$request->validated()` directly to\n`$user->update()`. The `AccountInfoRequest` whitelists the authentication column\n(`email` by default) with no ownership challenge. Contrast this with\n`ChangePasswordRequest`, which uses `Hash::check` against the stored password before\nallowing any change.\n\nScenarios where this is exploitable include:\n- A brief unauthorized session (e.g. unattended workstation, XSS in the admin panel)\n- An insider/offboarding case where a departing admin sets a personal email address\n before access is revoked, then resets the password after leaving\n\n## Patch\n\nFixed in [#5990](https://github.com/Laravel-Backpack/CRUD/pull/5990) — the\nauthentication column is now protected by a `current_password` check (mirroring\n`ChangePasswordRequest`) whenever its value changes.\n\nA stronger mitigation — sending a verification link to the new address before\npersisting the change — can be layered on top using Laravel's `MustVerifyEmail` flow.\n\n## Affected versions\n\nAll versions prior to 6.8.14 / 7.0.38.\n\n## Fixed versions\n\n- 6.x: 6.8.14\n- 7.x: 7.0.38",
