reqwest 0.12.28 redirect Cookie header removed host port scheme change redirect policy implementation

💡 Result:

<search_synthesis>
In reqwest version 0.12.28, the removal of sensitive headers (such as Cookie and Authorization) during redirects is handled by the remove_sensitive_headers function in src/redirect.rs [1][2]. This function ensures that sensitive headers are stripped when a redirect crosses an origin boundary [1][2]. Specifically, it checks for changes in the host, effective port, or scheme [1][2]. If any of these components differ between the previous URL and the next URL, the following headers are removed: - Authorization [1][2] - Cookie [1][2] - cookie2 [1][2] - Proxy-Authorization [1][2] - WWW-Authenticate [1][2] A security issue (tracked as issue #2985) previously existed where sensitive headers were retained during HTTPS to HTTP redirects if the host and port remained the same [3]. This was addressed in pull request #3034, which updated the remove_sensitive_headers logic to explicitly include a scheme comparison (next.scheme() != previous.scheme()) in the cross-origin check [4][3]. This fix ensures that transport downgrades (e.g., HTTPS to HTTP) correctly trigger the removal of sensitive headers, even if the host and port are identical [4][3]. The reqwest redirect policy implementation uses this function to maintain security when following redirects automatically [1][5]. Users can also define custom redirect policies using redirect::Policy::custom, which provides access to the redirect attempt information, though they must ensure they handle sensitive header security if they override default behaviors [6].

It ignores scheme changes. As a result, a redirect like: - `https://example.com:8443/start` - `302 Location: http://example.com:8443/next` is treated as safe for forwarding `Authorization` and `Cookie`, even though it is a transport downgrade. This is narrower than a generic HTTPS→HTTP redirect bug: the issue appears when the scheme changes but the effective port stays the same. ### Reproduction A minimal repo-local regression test is to add this next to `test_remove_sensitive_headers`: ```rust #[test] fn test_remove_sensitive_headers_on_https_to_http_downgrade_same_host_port() { use hyper::header::{HeaderValue, ACCEPT, AUTHORIZATION, COOKIE}; let mut headers = HeaderMap::new(); headers.insert(ACCEPT, HeaderValue::from_static("*/*")); headers.insert(AUTHORIZATION, HeaderValue::from_static("let me in")); headers.insert(COOKIE, HeaderValue::from_static("foo=bar")); let next = Url::parse("http://initial-domain.com:8443/path").unwrap(); let prev = vec![Url::parse("https://initial-domain.com:8443/new_path").unwrap()]; let mut filtered_headers = headers.clone(); filtered_headers.remove(AUTHORIZATION); filtered_headers.remove(COOKIE); remove_sensitive_headers(&mut headers, &next, &prev); assert_eq!(headers, filtered_headers); } ``` This currently fails because the headers are retained. ### Expected behavior Sensitive headers should be stripped when a redirect crosses an origin boundary, including a scheme change. At minimum, an HTTPS→HTTP downgrade should never forward `Authorization` or an explicitly set `Cookie` header. ### Actual behavior Sensitive headers are preserved across HTTPS→HTTP redirects as long as host and `port_or_known_default()` match. ### Impact Reqwest can resend credentials over cleartext HTTP after following a downgrade ## Timeline - Referenced by PR `steipete#3034`: fix(redirect): strip sensitive headers on scheme change across redirects - seanmonstar closed - Referenced by PR `#14`: feat(rust): NATS WebSocket + pluggable auth - Referenced by PR `#80`: Feat: Mise en place jetbrains marketplace et rework de la doc - Referenced by PR `#9524`: cmux-tui: broker-registered iroh transport sidecar (stage 1) - Referenced by PR `steipete#875`: feat(mcp): single-server endpoint /mcp/{server} with original tool names - Referenced by PR `steipete#691`: merge(swarm): promote shiplog-swarm through efc28db03545 - Referenced by PR `#169`: feat: add AI script and schedule import - Referenced by PR `#536`: feat: split OpenCompany into an orchestration server and a desktop client - Referenced by PR `#92`: sentry: promote unresolved Sentry issues into tracked GitHub issues - Referenced by PR `#8`: Add Supermemory, Mem0, and Cognee memory adapters - Referenced by PR `steipete#856`: feat(billing): Chargebee invoicing + PayPal wallet as agent tools (`steipete#788`, `steipete#789`, `#527`) - Referenced by PR `#11`: Gate GitHub exercise-seeding token by an owner allowlist - Referenced by PR `#98`: fix(ds5): reuse updater mirrors for component downloads <title>fix(redirect): strip sensitive headers on scheme change across redirects</title> GitHub pull request 3034 in seanmonstar/reqwest (link omitted to avoid creating a cross-reference) # fix(redirect): strip sensitive headers on scheme change across redirects - State: merged - Author: SAY-5 - Created: 2026-05-12T21:28:16Z - Updated: 2026-05-13T13:06:06Z - Repository: seanmonstar/reqwest - Number: `steipete#3034` - +22 -1 in 1 files - Merged: 2026-05-13T13:06:05Z - Merge commit: 03db63a48f35135c2f2c8b7aaa578217d5f678fe --- `remove_sensitive_headers` only compared host and effective port, so an `https://host:8443` to `http://host:8443` redirect kept `Authorization`/`Cookie` across a cleartext downgrade.

site:docs.rs/reqwest/0.12.28 reqwest redirect.rs remove_sensitive_headers Cookie scheme

💡 Result:

<search_synthesis>
The reqwest crate documentation for version 0.12.28 does not contain a feature or method explicitly named remove_sensitive_headers [1]. While reqwest provides a customizable redirect policy via redirect::Policy and supports cookie session management through the cookie_store method on ClientBuilder, there is no documented mechanism that automatically strips sensitive headers like Cookie during a redirect [1]. Users requiring specific header handling during redirects must implement custom logic using the available redirect policy configuration [1].

reqwest 0.12.28 GitHub tag redirect.rs remove_sensitive_headers source

💡 Result:

<search_synthesis>
In reqwest version 0.12.28, the remove_sensitive_headers function in src/redirect.rs was responsible for stripping sensitive headers (such as Authorization, Cookie, and Proxy-Authorization) when a redirect crossed an origin boundary [1][2]. At the time of the 0.12.28 release (December 2025), this function determined whether a redirect was "cross-host" by comparing only the host and the effective port of the next and previous URLs [1][2]. It did not explicitly compare the URL scheme [3][4]. Consequently, this implementation allowed sensitive headers to be retained during HTTPS-to-HTTP protocol downgrades if the host and port remained the same [3][4]. This behavior was later identified as a security issue (tracked in issue #2985) and was resolved in a subsequent release via pull request #3034, which updated the logic to include a scheme comparison in the cross-origin check [3][4]. The source code for remove_sensitive_headers in versions prior to the fix (including 0.12.28) generally followed this pattern [1][2]: pub(crate) fn remove_sensitive_headers(headers: &mut HeaderMap, next: &Url, previous: &[Url]) { if let Some(previous) = previous.last { let cross_host = next.host_str!= previous.host_str || next.port_or_known_default!= previous.port_or_known_default || next.scheme!= previous.scheme; // Note: The fix added this check if cross_host { headers.remove(AUTHORIZATION); headers.remove(COOKIE); headers.remove("cookie2"); headers.remove(PROXY_AUTHORIZATION); headers.remove(WWW_AUTHENTICATE); } } } (Note: In 0.12.28, the line checking next.scheme!= previous.scheme was absent, which is why the downgrade vulnerability existed [3][4].)

It ignores scheme changes. As a result, a redirect like: - `https://example.com:8443/start` - `302 Location: http://example.com:8443/next` is treated as safe for forwarding `Authorization` and `Cookie`, even though it is a transport downgrade. This is narrower than a generic HTTPS→HTTP redirect bug: the issue appears when the scheme changes but the effective port stays the same. ### Reproduction A minimal repo-local regression test is to add this next to `test_remove_sensitive_headers`: ```rust #[test] fn test_remove_sensitive_headers_on_https_to_http_downgrade_same_host_port() { use hyper::header::{HeaderValue, ACCEPT, AUTHORIZATION, COOKIE}; let mut headers = HeaderMap::new(); headers.insert(ACCEPT, HeaderValue::from_static("*/*")); headers.insert(AUTHORIZATION, HeaderValue::from_static("let me in")); headers.insert(COOKIE, HeaderValue::from_static("foo=bar")); let next = Url::parse("http://initial-domain.com:8443/path").unwrap(); let prev = vec![Url::parse("https://initial-domain.com:8443/new_path").unwrap()]; let mut filtered_headers = headers.clone(); filtered_headers.remove(AUTHORIZATION); filtered_headers.remove(COOKIE); remove_sensitive_headers(&mut headers, &next, &prev); assert_eq!(headers, filtered_headers); } ``` This currently fails because the headers are retained. ### Expected behavior Sensitive headers should be stripped when a redirect crosses an origin boundary, including a scheme change. At minimum, an HTTPS→HTTP downgrade should never forward `Authorization` or an explicitly set `Cookie` header. ### Actual behavior Sensitive headers are preserved across HTTPS→HTTP redirects as long as host and `port_or_known_default()` match. ### Impact Reqwest can resend credentials over cleartext HTTP after following a downgrade ## Timeline - Referenced by PR `steipete#3034`: fix(redirect): strip sensitive headers on scheme change across redirects - seanmonstar closed - Referenced by PR `#14`: feat(rust): NATS WebSocket + pluggable auth - Referenced by PR `#80`: Feat: Mise en place jetbrains marketplace et rework de la doc - Referenced by PR `#9524`: cmux-tui: broker-registered iroh transport sidecar (stage 1) - Referenced by PR `steipete#875`: feat(mcp): single-server endpoint /mcp/{server} with original tool names - Referenced by PR `steipete#691`: merge(swarm): promote shiplog-swarm through efc28db03545 - Referenced by PR `#169`: feat: add AI script and schedule import - Referenced by PR `#536`: feat: split OpenCompany into an orchestration server and a desktop client - Referenced by PR `#92`: sentry: promote unresolved Sentry issues into tracked GitHub issues - Referenced by PR `#8`: Add Supermemory, Mem0, and Cognee memory adapters - Referenced by PR `steipete#856`: feat(billing): Chargebee invoicing + PayPal wallet as agent tools (`steipete#788`, `steipete#789`, `#527`) - Referenced by PR `#11`: Gate GitHub exercise-seeding token by an owner allowlist - Referenced by PR `#98`: fix(ds5): reuse updater mirrors for component downloads <title>fix(redirect): strip sensitive headers on scheme change across redirects</title> GitHub pull request 3034 in seanmonstar/reqwest (link omitted to avoid creating a cross-reference) # fix(redirect): strip sensitive headers on scheme change across redirects - State: merged - Author: SAY-5 - Created: 2026-05-12T21:28:16Z - Updated: 2026-05-13T13:06:06Z - Repository: seanmonstar/reqwest - Number: `steipete#3034` - +22 -1 in 1 files - Merged: 2026-05-13T13:06:05Z - Merge commit: 03db63a48f35135c2f2c8b7aaa578217d5f678fe --- `remove_sensitive_headers` only compared host and effective port, so an `https://host:8443` to `http://host:8443` redirect kept `Authorization`/`Cookie` across a cleartext downgrade.

Sensitive Data Exposure

Reachability: External
Exploitability: Difficult
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Reject non-HTTPS redirects before reqwest follows them.

reqwest 0.12.28 strips Cookie when the host or effective port changes, but its redirect handling does not treat a scheme-only change as sensitive. A redirect from https://admin.mistral.ai to http://admin.mistral.ai:443 can therefore forward the cookie over cleartext before response.url() is checked. Configure the redirect policy to reject every non-HTTPS redirect and any host other than admin.mistral.ai before sending the next request. Keep the final URL check as defense in depth.

Set the monthly window duration when a reset is known.

budget_window passes None for window_minutes. The monthly reset is preserved, but pace consumers cannot identify the monthly cadence. The CLI omits pace for this primary window, and predictive pace calculations use their default instead.
