{"id":"CVE-2026-44833","aliases":["GHSA-mghp-5cq4-v6mg"],"url":"https://o3.security/vulnerability/CVE-2026-44833","summary":"Snipe-IT: Open redirect vulnerability","details":"Open redirect vulnerability in Snipe-IT allows attackers to redirect users to malicious sites via unvalidated HTTP Referer header stored in session variable.\n\n### Impact\n\n-   **Phishing**: Redirect users to fake login pages to steal credentials\n-   **Session Hijacking**: Redirect to attacker site that captures session cookies via JavaScript\n-   **Malware Distribution**: Redirect to sites hosting malware or drive-by downloads\n-   **Reputation Damage**: Users lose trust when redirected to malicious sites from legitimate application\n-   **Social Engineering**: Use trusted Snipe-IT domain to increase phishing success rate\n\nWhen the user clicks \"Save\", the application: \n1. Processes the form \n2. Checks `redirect_option` (if set to 'back') \n3. Calls `Helper::getRedirectOption()` \n4. Retrieves `back_url` from session: `https://evil.com/phishing?target=snipeit` \n5. Executes `redirect()->to($backUrl)` \n6. User is redirected to attacker's site\n\nThis would still require session poisoning, so the actual practical threat here is minimal. \n\n### Patches\nPatched in https://github.com/grokability/snipe-it/commit/e37649212861a337e68a624e589c3540b7a82373, released in 8.4.1.\n\n### Workarounds\n None.\n\n### Resources\n-   CWE-601: URL Redirection to Untrusted Site ('Open Redirect')\n-   OWASP: Unvalidated Redirects and Forwards\n-   Laravel Security: Safe Redirects\n\n[snipeit_open_redirect_submission.md](https://github.com/user-attachments/files/27414869/snipeit_open_redirect_submission.md)","published":"2026-05-26T19:30:48.852Z","modified":"2026-08-27T03:57:09.126556338Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L"},"epss":{"score":0.00163,"percentile":0.05663,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"snipe/snipe-it","fixedVersion":"8.4.1"}],"fix":{"url":"https://github.com/grokability/snipe-it/commit/e37649212861a337e68a624e589c3540b7a82373","label":"grokability/snipe-it@e376492"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44833.json"},{"type":"ADVISORY","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-mghp-5cq4-v6mg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44833"},{"type":"FIX","url":"https://github.com/grokability/snipe-it/commit/e37649212861a337e68a624e589c3540b7a82373"},{"type":"PACKAGE","url":"https://github.com/grokability/snipe-it"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:57:09.126556338Z"}}
