PROFILE
Mustafa Emre Acer
Worked on enhancing Content Security Policy (CSP) handling in the mozilla/gecko-dev repository, focusing on URL hash allowlisting and its impact on script source evaluation. Developed comprehensive end-to-end tests in JavaScript and HTML to verify CSP’s parsing and application of URL hashes across directives, including script-src and default-src, and ensured correct behavior with both header and meta policies. Addressed a CSP bug affecting URL hash checks on initial URLs, expanded test coverage to dynamic scripts and redirects, and refactored test infrastructure to improve maintainability. These contributions strengthened CSP reliability and reduced regression risk in security-critical web platform scenarios.

Jun 1, 2025June 2025 monthly summary focused on strengthening CSP URL hash allowlisting testing in mozilla/gecko-dev. Delivered end-to-end tests for URL hash allowlisting across CSP directives (script-src, default-src, script-src-elem) and interactions with header/meta policies; verified parsing and application of URL hash-based allowlisting in script-src(v1) (commit 78ab26fd47a45357f276e627a535a46fb658238b). This work mitigates a CSP-related security risk and improves correctness of script source evaluation.
