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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","score":5.3,"severity":null}],"references":["https://github.com/projectdiscovery/nuclei/security/advisories/GHSA-jm34-66cf-qpvr","https://github.com/projectdiscovery/nuclei/pull/7221","https://github.com/projectdiscovery/nuclei/pull/7321","https://github.com/projectdiscovery/nuclei/commit/6c803c74d193f85f8a6d9803ce493fd302cad0eb","https://github.com/projectdiscovery/nuclei/commit/d2217320162d5782ca7cb95bef9dda17063818f3","https://github.com/projectdiscovery/nuclei/releases/tag/v3.8.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-28498","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"May 8, 2026, 3:17:19 AM","dateUpdated":"May 11, 2026, 6:16:02 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
