GHSA-vqxq-hvxw-9mv9 — statamic/cms
HIGHGHSA-vqxq-hvxw-9mv9 is a high-severity (CVSS 8.2) Cross-site Scripting (XSS) vulnerability in statamic/cms. A fix is available for statamic/cms — see the affected versions and patch details below.
Statmic CMS vulnerable to account takeover via XSS and password reset link
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

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-vqxq-hvxw-9mv9 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 378,156 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.
Real-World Exposure
statamic/cms🐘statamic/cmsReal-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
Impact
HTML files crafted to look like jpg files are able to be uploaded, allowing for XSS.
This affects:
- front-end forms with asset fields without any mime type validation
- asset fields in the control panel
- asset browser in the control panel
Additionally, if the XSS is crafted in a specific way, the "copy password reset link" feature may be exploited to gain access to a user's password reset token and gain access to their account. The authorized user is required to execute the XSS in order for the vulnerability to occur.
Patches
In versions 4.46.0 and 3.4.17, the XSS vulnerability has been patched, and the copy password reset link functionality has been disabled. (Users may still trigger password reset emails.)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update statamic/cms to 4.46.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vqxq-hvxw-9mv9 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vqxq-hvxw-9mv9 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vqxq-hvxw-9mv9. 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-vqxq-hvxw-9mv9 in your dependencies?
O3 Security finds GHSA-vqxq-hvxw-9mv9 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
