• CVE-2024-23817: 0.56% estimated exploitation activity in the next 30 days; percentile 46.46 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary Observed a HTML Injection vulnerbaility in the Home page of Dolibarr Application. This vulnerability allows an attacker to inject arbitrary HTML tags and manipulate the rendered content in the application's response. Specifically, I was able to successfully inject a new HTML tag into the returned document and, as a result, was able to comment out some part of the Dolibarr App Home page HTML code. This behavior can be exploited to perform various attacks like Cross-Site Scripting (XSS). Details 1. Navigate to the login page of Dolibarr application. 2. Submit a login request with the following payload in an arbitrarily supplied body parameter: "u70ea%22%3e%3c!--HTMLInjectionBySai"=1 HTTP Post Request: POST /dolibarr/index.php?mainmenu=home HTTP/1.1 Host: 192.168.37.129 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,/;q=0.8 Accept-Language:…

# Patch Next advisory brief: CVE-2024-23817

Advisory: Dolibarr Application Home Page has HTML injection vulnerability
IDs: CVE-2024-23817, GHSA-7947-48q7-cp5m
Record: https://patchnext.com/advisories/cve-2024-23817 (revision 1, source checked 26 Oct 2026, 14:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: dolibarr/dolibarr 18.0.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist dolibarr/dolibarr: affected >= 18.0.4, < 18.0.7; fixed in 18.0.7

## Suggested inspection (read-only)
- Packagist dolibarr/dolibarr: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dolibarr/dolibarr.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-7947-48q7-cp5m (GitHub-reviewed advisory GHSA-7947-48q7-cp5m lists affected ranges: Packagist dolibarr/dolibarr >=18.0.4 <18.0.7)
