This allows the attacker to remove specific headers that the proxy has added for security, routing, or access control purpose...

GHSA-CPF9-PH2J-CCR9 zrok: Unauthenticated DoS via unbounded memory allocation in striped session cookie parsing

Summary endpoints.GetSessionCookie parses an attacker-supplied cookie chunk count and calls makestring, count with no upper bound before any token validation occurs. The function is reached on every request to an OAuth-protected proxy share, allowing an unauthenticated remote attacker to trigger...

GHSA-4FXQ-2X3X-6XQX zrok: Reflected XSS in GitHub OAuth callback via unsanitized refreshInterval error rendering

Summary The proxyUi template engine uses Go's text/template which performs no HTML escaping instead of html/template. The GitHub OAuth callback handlers in both publicProxy and dynamicProxy embed the attacker-controlled refreshInterval query parameter verbatim into an error message when...

curl: CVE-2026-6429: netrc credential leak with reused proxy connection

Summary: libcurl can leak .netrc-derived host Authorization credentials across redirected hosts when an HTTP proxy connection is reused. In the PoC, .netrc contains credentials only for a.test, but after a.test redirects to b.test and then c.test over the same keep-alive proxy connection, libcurl...

Improper Access Control
