HIGHGHSA-rrmf-fpmm-jpwr is a high-severity (CVSS 8.8) Cross-Site Request Forgery (CSRF) vulnerability in opensolutions/vimbadmin. 2 public exploit references exist, so weaponization risk is real. No vendor fix is recorded yet; mitigation options are listed below.
ViMbAdmin CSRF Vulnerabilities
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-rrmf-fpmm-jpwr plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Multiple cross-site request forgery (CSRF) vulnerabilities in the addAction and purgeAction functions in ViMbAdmin 3.0.15 allow remote attackers to hijack the authentication of logged administrators to
- add an administrator user via a crafted POST request to
<vimbadmin directory>/application/controllers/DomainController.php, - remove an administrator user via a crafted GET request to
<vimbadmin directory>/application/controllers/DomainController.php, - change an administrator password via a crafted POST request to
<vimbadmin directory>/application/controllers/DomainController.php, - add a mailbox via a crafted POST request to
<vimbadmin directory>/application/controllers/MailboxController.php, - delete a mailbox via a crafted POST request to
<vimbadmin directory>/application/controllers/MailboxController.php, - archive a mailbox address via a crafted GET request to
<vimbadmin directory>/application/controllers/ArchiveController.php, - add an alias address via a crafted POST request to
<vimbadmin directory>/application/controllers/AliasController.php, or - remove an alias address via a crafted GET request to
<vimbadmin directory>/application/controllers/AliasController.php.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for opensolutions/vimbadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of opensolutions/vimbadmin has shipped for GHSA-rrmf-fpmm-jpwr 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-rrmf-fpmm-jpwr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-rrmf-fpmm-jpwr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-rrmf-fpmm-jpwr in your dependencies?
O3 Security finds GHSA-rrmf-fpmm-jpwr across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
