Camaleon CMS Vulnerable to Privilege Escalation through a Mass Assignment
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- 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
A Privilege Escalation through a Mass Assignment exists in Camaleon CMS
When a user wishes to change his password, the 'updated_ajax' method of the UsersController is called. The vulnerability stems from the use of the dangerous permit! method, which allows all parameters to pass through without any filtering.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for camaleon_cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update camaleon_cms to 2.9.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-2304 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 CVE-2025-2304 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-2304. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-2304 in your dependencies?
O3 Security finds CVE-2025-2304 across RubyGems dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
