CVE-2021-25954 is a medium-severity (CVSS 4.3) CWE-284 vulnerability in dolibarr/dolibarr. O3 Security confirms whether CVE-2021-25954 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper Access Control in Dolibarr
Real-World Exposure
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 “Dolibarr” application, 2.8.1 to 13.0.4 don’t restrict or incorrectly restricts access to a resource from an unauthorized actor. A low privileged attacker can modify the Private Note which only an administrator has rights to do, the affected field is at “/adherents/note.php?id=1” endpoint.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | dolibarr/dolibarr | ≥ 2.8.1&&< 14.0.0 | 14.0.0 |
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.
Fix
Update dolibarr/dolibarr to 14.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-25954 is resolved across your whole dependency graph.
Workarounds
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-2021-25954 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-2021-25954. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2021-25954 in your dependencies?
O3 detects CVE-2021-25954 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
