CVE-2026-44833

Open redirect vulnerability in Snipe-IT allows attackers to redirect users to malicious sites via unvalidated HTTP Referer header stored in session variable.

Workarounds

None.

Resources

• CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
• OWASP: Unvalidated Redirects and Forwards
• Laravel Security: Safe Redirects

snipeit_open_redirect_submission.md

• 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 redirect_option (if set to 'back')
3. Calls Helper::getRedirectOption()
4. Retrieves back_url 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.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

CVE-2026-44833 has a CVSS score of 5.9 (Medium). The vector is reachable from an adjacent network, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (8.4.1); upgrading removes the vulnerable code path.

1. What is CVE-2026-44833? CVE-2026-44833 is a medium-severity open redirect vulnerability in snipe/snipe-it (composer), affecting versions < 8.4.1. It is fixed in 8.4.1. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is CVE-2026-44833? CVE-2026-44833 has a CVSS score of 5.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of snipe/snipe-it are affected by CVE-2026-44833? snipe/snipe-it (composer) versions < 8.4.1 is affected.
4. Is there a fix for CVE-2026-44833? Yes. CVE-2026-44833 is fixed in 8.4.1. Upgrade to this version or later.
5. Is CVE-2026-44833 exploitable, and should I be worried? Whether CVE-2026-44833 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-44833 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-44833? Upgrade snipe/snipe-it to 8.4.1 or later.
