How do I fix GHSA-qrfh-cc86-vc8c?

Update leantime/leantime to 3.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qrfh-cc86-vc8c is resolved across your whole dependency graph.

How do I detect GHSA-qrfh-cc86-vc8c in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for leantime/leantime. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-qrfh-cc86-vc8c if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-qrfh-cc86-vc8c?

O3 pinpoints whether GHSA-qrfh-cc86-vc8c is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-qrfh-cc86-vc8c actively exploited in the wild?

No public exploit code has been indexed for GHSA-qrfh-cc86-vc8c yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Summary

Leantime v2.3.27 is vulnerable to Stored HTML Injection. The firstname and lastname fields in the admin user edit page are rendered without HTML escaping, allowing an authenticated user to inject arbitrary HTML that executes when the profile is viewed.

Vulnerable File

app/Domain/Users/Templates/editUser.tpl.php

Vulnerable Code (Lines ~14-17)

value="<?php echo $values['firstname'] ?>"
value="<?php echo $values['lastname'] ?>"

These fields output raw user input without sanitization.

Steps to Reproduce

Login as admin > Go to Settings > Users > Edit any user
Enter HTML payload in First Name or Last Name field: <h1>INJECTED</h1>
Save the user profile
Create or view an article — the injected HTML renders in the author name

Fix

Replace unescaped echo with htmlspecialchars():

value="<?php echo htmlspecialchars($values['firstname'], ENT_QUOTES, 'UTF-8') ?>"
value="<?php echo htmlspecialchars($values['lastname'], ENT_QUOTES, 'UTF-8') ?>"

Or use the existing $this->e() helper already used in editOwn.tpl.php.

Impact

Stored HTML injection visible to all users viewing affected content
Can be used for phishing, fake login forms, and UI defacement
Affects all versions before 3.3.0
