• CVE-2026-44833: 0.16% estimated exploitation activity in the next 30 days; percentile 5.51 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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: 1. Processes the form 2. Checks redirectoption (if set to 'back') 3. Calls Helper::getRedirectOption() 4. Retrieves backurl from session: https://evil.com/phishing?target=snipeit 5. Executes redirect()-to($backUrl) 6. User is redirected to attacker's site This would still require session poisoning, so the actual practical threat here is minimal. Patches…

# Patch Next advisory brief: CVE-2026-44833

Advisory: Snipe-IT has an open redirect vulnerability
IDs: CVE-2026-44833, GHSA-mghp-5cq4-v6mg
Record: https://patchnext.com/advisories/cve-2026-44833 (revision 1, source checked 26 Oct 2026, 14:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: snipe/snipe-it 8.4.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist snipe/snipe-it: affected < 8.4.1; fixed in 8.4.1

## Suggested inspection (read-only)
- Packagist snipe/snipe-it: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on snipe/snipe-it.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-mghp-5cq4-v6mg (GitHub-reviewed advisory GHSA-mghp-5cq4-v6mg lists affected ranges: Packagist snipe/snipe-it >=0 <8.4.1)
