CVE-2019-15952 — total4
HIGHCVE-2019-15952 is a high-severity (CVSS 8.8) Path Traversal vulnerability in total4. 2 public exploit references exist, so weaponization risk is real. No vendor fix is recorded yet; mitigation options are listed below.
Total.js CMS Path Traversal
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2019-15952 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,238 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
total4npmDescription
An issue was discovered in Total.js CMS 12.0.0. An authenticated user with the Pages privilege can conduct a path traversal attack (../) to include .html files that are outside the permitted directory. Also, if a page contains a template directive, then the directive will be server side processed. Thus, if a user can control the content of a .html file, then they can inject a payload with a malicious template directive to gain Remote Command Execution. The exploit will work only with the .html extension.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for total4, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of total4 has shipped for CVE-2019-15952 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-2019-15952 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2019-15952. 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-2019-15952 in your dependencies?
O3 Security finds CVE-2019-15952 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
