Exploitation Status

No confirmed exploitation observed yet

  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    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.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-54417 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2025-54417. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
