Description
NivoCart through 2.4.0 contains an arbitrary file upload vulnerability in the File Manager multi() endpoint that fails to validate file extensions for new filenames or when chunks parameter is 2 or higher. Attackers with view-only back-office access can upload PHP files to the web-accessible image/data/ directory and execute them for remote code execution.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of the affected component has shipped for CVE-2026-94104 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2026-94104 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-94104. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
