Kimai is an open-source time tracking application. In versions 1.16.3 through 2.52.0, the escapeForHtml() function in KimaiEscape.js does not escape double quote or single quote characters. When a user's profile alias is inserted into an HTML attribute context via the team member form prototype and rendered through innerHTML, this incomplete escaping allows HTML attribute injection. An authenticated user with ROLE_USER privileges can store a malicious alias that executes JavaScript in the browser of any administrator viewing the team form, resulting in stored XSS with privilege escalation. This issue has been fixed in version 2.53.0.

Affected: Packagist: kimai/kimai

### Summary The client-side `escapeForHtml()` function in `KimaiEscape.js`, introduced in commit `89bfa82c` (#2959) to fix a JavaScript XSS vulnerability, only escapes `<`, `>`, and `&` but does not escape `"` (double quote) or `'` (single quote). When user-controlled data (profile alias) is placed in an HTML attribute context (`title="__DISPLAY__"`) via the team member form prototype and rendered through `innerHTML`, the missing quote escaping allows HTML attribute injection, resulting in Stored XSS.

### Details Incomplete security patch. The `escapeForHtml()` function was meant to prevent XSS but missed quote characters, which are critical for HTML attribute context escaping.

**Vulnerable code** — `assets/js/plugins/KimaiEscape.js:29-33`: ```javascript const tagsToReplace = { '&': '&amp;', '<': '&lt;', '>': '&gt;', // MISSING: '"': '&quot;' // MISSING: "'": '&#039;' }; ```

**Affected code files**: - `assets/js/plugins/KimaiEscape.js:24-38` — incomplete escape function - `assets/js/forms/KimaiTeamForm.js:77,86` — replacement + innerHTML - `templates/macros/widgets.html.twig:126` — `title="{{ tooltip }}"` in avatar macro - `templates/form/blocks.html.twig:104` — `{{ widgets.avatar('__INITIALS__', '__COLOR__', '__DISPLAY__') }}`
