| Severity | Category | Title | Affected Component |
| :--- | :--- | :--- | :--- |
| **HIGH** | Cross-Site Scripting | Unsanitized `v-html` Rendering of User Input | `ppr-ui` |

### Stored Cross-Site Scripting (XSS) via Unsanitized `v-html` Rendering
- **Severity**: High (CVSS 7.2)
- **Category**: CWE-79 (Cross-Site Scripting)
- **Locations**:
- [`ppr-ui/src/components/collateral/general/GenColSummary.vue:L115, L133, L188, L206, L232, L248`](file:///Users/thor/Developer/redteam/ppr/ppr-ui/src/components/collateral/general/GenColSummary.vue#L115)
- [`ppr-ui/src/components/unitNotes/UnitNoteReviewDetailsTable.vue:L49`](file:///Users/thor/Developer/redteam/ppr/ppr-ui/src/components/unitNotes/UnitNoteReviewDetailsTable.vue#L49)
- [`ppr-ui/src/components/common/CautionBox.vue:L9`](file:///Users/thor/Developer/redteam/ppr/ppr-ui/src/components/common/CautionBox.vue#L9)

#### Description
In `GenColSummary.vue` and `UnitNoteReviewDetailsTable.vue`, user-submitted text descriptions (such as general collateral additions/deletions or unit note remarks) are rendered directly using Vue's `v-html` directive:

```html

```

If an attacker inputs malicious HTML tags (e.g., ``) into collateral text fields, the script will execute in the browser of any user or staff member reviewing the registration.

#### Remediation
Replace `v-html` with standard Vue text interpolation `{{ ... }}` or sanitize inputs using DOMPurify before rendering:
```html
{{ lastGeneralCollateral.descriptionAdd }}
```

Review the listed v-html locations in ppr-ui/src/components/collateral/general/GenColSummary.vue, ppr-ui/src/components/unitNotes/UnitNoteReviewDetailsTable.vue, and ppr-ui/src/components/common/CautionBox.vue. Replace unsafe rendering with text interpolation or sanitize the values as appropriate, then verify that user-supplied text is displayed without executing HTML or scripts.
