Identify all Node.js and Java Spring Boot applications running sealed-env versions 0.1.0-alpha.1 through 0.1.0-alpha.3.\n2. Update dependencies in package.json or pom.xml/build.gradle to target sealed-env version 0.1.0-alpha.4.\n3. Deploy the updated application to production environments.\n4. Access the sealed-env administrative interface and invalidate all existing operator TOTP configurations.\n5. Require operators to register new TOTP credentials.\n6. Search centralized logging systems and CI/CD pipelines for existing JWS tokens and delete the offending records.\n\n## References\n\n- [GHSA Advisory](https://github.com/davidalmeidac/sealed-env/security/advisories/GHSA-x3r2-fj3r-g5mv)\n- [NVD Entry](https://nvd.nist.gov/vuln/detail/CVE-2026-45091)\n- [CVE Record](https://www.cve.org/CVERecord?id=CVE-2026-45091)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-45091) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-05-12T16:10:29.000000Z"}, {"uuid": "1ee97780-dc8b-443c-afa8-37cdc374201f", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-45091", "type": "published-proof-of-concept", "source": "Telegram/mjKYtwBGh-p48w8zvyK_dmOaa4JWuY9k0ugNTHKD_EJnGeA", "content": "", "creation_timestamp": "2026-05-16T07:00:12.000000Z"}, {"uuid": "65313c6e-f6ab-46ea-8853-5a227544746b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-45091", "type": "published-proof-of-concept", "source": "Telegram/qFnncewX_FdOxDivGoEqJX19AvA6N2dSwzORt9UZIQWFUQU", "content": "", "creation_timestamp": "2026-05-17T02:07:47.000000Z"}, {"uuid": "761562c2-9f4b-454a-9efb-4c6d054a5f61", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-45090", "type": "published-proof-of-concept", "source": "https://github.com/hahwul/dalfox/security/advisories/GHSA-2g4x-fq3j-cgq4", "content": "", "creation_timestamp": "2026-05-07T13:30:22.000000Z"}]}
