From version 3.0.0 to before version 3.8.0, a vulnerability in Nuclei's expression evaluation engine makes it possible for a malicious target server to inject and execute supported DSL expressions. This happens when HTTP response data containing helper/function syntax gets reused by multi-step templates. If the -env-vars / -ev option is explicitly enabled, this can expose host environment variables. That option is off by default, so standard configurations are not affected by the information disclosure risk. This issue has been patched in version 3.8.0.","state":0,"publishedAt":"2026-05-08T04:16:18.177+00:00","modifiedAt":"2026-10-26T20:10:00.16+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/projectdiscovery/nuclei/commit/6c803c74d193f85f8a6d9803ce493fd302cad0eb","https://github.com/projectdiscovery/nuclei/commit/d2217320162d5782ca7cb95bef9dda17063818f3","https://github.com/projectdiscovery/nuclei/pull/7221","https://github.com/projectdiscovery/nuclei/pull/7321","https://github.com/projectdiscovery/nuclei/releases/tag/v3.8.0","https://github.com/projectdiscovery/nuclei/security/advisories/GHSA-jm34-66cf-qpvr"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41645","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-94"],"productCriteria":["cpe:2.3:a:projectdiscovery:nuclei:*:*:*:*:*:go:*:*"],"sourceDates":{"published":"2026-05-08T04:16:18.177","lastModified":"2026-10-26T20:10:00.160"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
