fix(csp): allow worker-src 'self' blob: for Clerk - #18
Merged
Merged
Conversation
Clerk creates Web Workers from blob: URLs. The policy had no worker-src, so browsers fell back to script-src, which does not allow blob:, and the console filled with CSP violations. Add worker-src 'self' blob: and leave every other directive unchanged (the pinned production policy in csp.test.ts gains exactly this directive).

What
Add
worker-src 'self' blob:to the CSP built bysrc/lib/csp.ts, whichnext.config.tssets on every response. No other directive changes.Why
Clerk starts Web Workers from
blob:URLs. The policy had noworker-src, so browsers fell back toscript-src, which doesn't allowblob:, and the console logged blocked-worker errors.Verified
csp.test.ts: the pinned production policy gains exactly this directive, and a new test asserts it.npx vitest run(236 passed), eslint and tsc are clean.After merge
Nothing beyond the normal Vercel production deploy. The CSP is set at build time.
