CVE-2026-31019
HIGHCVE-2026-31019 is a high-severity (CVSS 8.8) OS Command Injection vulnerability in dolibarr/dolibarr. O3 Security confirms whether CVE-2026-31019 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
dolibarr/dolibarrReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
In the Website module of Dolibarr ERP & CRM 22.0.4 and below, the application uses blacklist-based filtering to restrict dangerous PHP functions related to system command execution. An authenticated user with permission to edit PHP content can bypass this filtering, resulting in full remote code execution with the ability to execute arbitrary operating system commands on the server.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dolibarr/dolibarr. 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.
Remediation status
No patched version of dolibarr/dolibarr has shipped for CVE-2026-31019 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 pinpoints whether CVE-2026-31019 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-31019. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
