Worked on security hardening and accuracy improvements for the projectdiscovery/nuclei-templates repository, focusing on refining detection logic and reducing false positives. Addressed CVE-2018-11776 by updating YAML-based templates to properly handle 302 redirects containing OGNL in the Location header, enhancing matchers to support both 200 and 302 responses and generalizing Location header detection. Improved DNS CAA template reliability by restricting matches to the ANSWER section and applying a precise Regex-based word matcher for 'CAA'. Leveraged skills in DNS, Regex, and YAML configuration to deliver targeted vulnerability management, resulting in improved detection fidelity and reduced scan noise for security operations.
