No CVSS score has been assigned to CVE-2025-54417 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-54417?

CVE-2025-54417 affects the following packages: craftcms/cms (Packagist), craftcms/cms (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2025-54417?

Update craftcms/cms to 4.16.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-54417 is resolved across your whole dependency graph.

How do I detect CVE-2025-54417 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/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-2025-54417 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-2025-54417?

O3 pinpoints whether CVE-2025-54417 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-2025-54417 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-54417 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-2025-54417?

CVE-2025-54417 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 36th 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.

What type of vulnerability is CVE-2025-54417?

CVE-2025-54417 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-54417 published, and has it been updated?

CVE-2025-54417 was published on August 9, 2025 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

Craft is a platform for creating digital experiences. Versions 4.13.8 through 4.16.2 and 5.5.8 through 5.8.3 contain a vulnerability that can bypass CVE-2025-23209: "Craft CMS has a potential RCE with a compromised security key". To exploit this vulnerability, the project must meet these requirements: have a compromised security key and create an arbitrary file in Craft's /storage/backups folder. With those criteria in place, attackers could create a specific, malicious request to the /updater/restore-db endpoint and execute CLI commands remotely. This issue is fixed in versions 4.16.3 and 5.8.4.
