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-2026-44833 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 378,156 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

Description
Open redirect vulnerability in Snipe-IT allows attackers to redirect users to malicious sites via unvalidated HTTP Referer header stored in session variable.
Impact
- Phishing: Redirect users to fake login pages to steal credentials
- Session Hijacking: Redirect to attacker site that captures session cookies via JavaScript
- Malware Distribution: Redirect to sites hosting malware or drive-by downloads
- Reputation Damage: Users lose trust when redirected to malicious sites from legitimate application
- Social Engineering: Use trusted Snipe-IT domain to increase phishing success rate
When the user clicks "Save", the application:
- Processes the form
- Checks
redirect_option(if set to 'back') - Calls
Helper::getRedirectOption() - Retrieves
back_urlfrom session:https://evil.com/phishing?target=snipeit - Executes
redirect()->to($backUrl) - User is redirected to attacker's site
This would still require session poisoning, so the actual practical threat here is minimal.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snipe/snipe-it, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update snipe/snipe-it to 8.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44833 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-2026-44833 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-44833. 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-2026-44833 in your dependencies?
O3 Security finds CVE-2026-44833 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
