How severe is CVE-2026-28425?

CVE-2026-28425 has a CVSS score of 8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2026-28425?

CVE-2026-28425 affects the following packages: statamic/cms (Packagist), statamic/cms (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2026-28425?

Update statamic/cms to 5.73.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-28425 is resolved across your whole dependency graph.

How do I detect CVE-2026-28425 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms. 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.

How do I mitigate CVE-2026-28425 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2026-28425?

O3 pinpoints whether CVE-2026-28425 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-28425 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-28425 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-28425?

CVE-2026-28425 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 34th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2026-28425 published, and has it been updated?

CVE-2026-28425 was published on February 27, 2026 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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

Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, an authenticated control panel user with access to Antlers-enabled inputs may be able to achieve remote code execution in the application context. That can lead to full compromise of the application, including access to sensitive configuration, modification or exfiltration of data, and potential impact on availability. Exploitation is only possible where Antlers runs on user-controlled content—for example, content fields with Antlers explicitly enabled (requiring permission to configure fields and to edit entries), built-in config that supports Antlers such as Forms email notification settings (requiring configuration permission), or third-party addons that add Antlers-enabled fields to entries (for example, the SEO Pro addon). In each case the attacker must have the relevant control panel permissions. This has been fixed in 5.73.16 and 6.7.2. Users of addons that depend on Statamic should ensure that after updating they are running a patched Statamic version.
