## Description
Add `CandlestickChart` component for visualizing financial OHLC data
with candlestick patterns.
- Introduced a new CandlestickChart for displaying OHLC (Open, High,
Low, Close) values.
- Updated ChartStory to include stock price data and render multiple
candlestick chart variations.
- Enhanced theme with bullish and bearish colors for candlestick
representation.
- Updated documentation to include CandlestickChart examples and usage.
This addition enhances the charting library by providing a crucial tool
for visualizing stock market trends.

## Description
This PR Adds the ability for users of the library to provide code block
actions for code blocks rendered in markdown (or anything that uses the
TextViewStyle).
I tried to match the existing Fns:
```rs
pub fn heading_font_size<F>(mut self, f: F) -> Self
where
F: Fn(u8, Pixels) -> Pixels + Send + Sync + 'static,
{
self.heading_font_size = Some(Arc::new(f));
self
}
```
New code in text_view:
```rs
pub fn code_block_actions<F, E>(mut self, f: F) -> Self
where
F: Fn(SharedString, Option<SharedString>, &mut Window, &mut App) -> E
+ Send
+ Sync
+ 'static,
E: IntoElement,
{
self.code_block_actions = Some(Arc::new(move |code, lang, window, cx| {
f(code, lang, window, cx).into_any_element()
}));
self
}
```
Example on adding a simple copy button:
```rs
TextView::markdown("preview", content, window, cx)
.code_block_actions(|code, _lang, _window, _cx| {
Clipboard::new("copy").value(code)
})
```

Closes#1665
## Description
When `Input::new().font_family("font")` is used, the font hasn't been
applied yet in `Input::render`, therefore the `text_wrapper` will
calculate using the wrong font. This is why it's working when the font
is added to the parent element.
The fix moves the state update to `element` prepaint, where
`window.text_style()` has the correct styles. The only downside is that
there are now one additional state update.

## Description
This PR fixes an issue where the editor's "reverse cursor" state was not
reset
after completing a text selection. Because the flag remained `true`, the
cursor
could appear on the wrong side of the selection when the next
interaction
started.

## Security Fix
This PR addresses a **LOW** severity vulnerability detected by our
security scanner.
### Security Impact Assessment
| Aspect | Rating | Rationale |
|--------|--------|-----------|
| Impact | Low | In the gpui-component repository, which is a Rust-based
GUI component library for building native apps, tracing log pollution
could allow misleading or polluted logs during application runtime,
potentially aiding in debugging obfuscation or minor information
leakage, but it poses minimal risk as the library focuses on UI
rendering and does not handle sensitive data or network operations
directly. |
| Likelihood | Low | The repository is a client-side GUI component
library, typically deployed in desktop or native applications with
limited network exposure, making exploitation unlikely as attackers
would need to compromise the local app environment first, and log
pollution requires specific conditions not common in this usage context.
|
| Ease of Fix | Easy | Remediation involves updating the
tracing-subscriber dependency in Cargo.lock to a patched version, which
is a straightforward Cargo update with minimal risk of breaking changes
in a component library focused on UI elements rather than core logic. |
### Evidence: Proof-of-Concept Exploitation Demo
**⚠️ For Educational/Security Awareness Only**
This demonstration shows how the vulnerability could be exploited to
help you understand its severity and prioritize remediation.
#### How This Vulnerability Can Be Exploited
The vulnerability in CVE-2025-58160 affects the `tracing-subscriber`
crate, a transitive dependency in this Rust-based UI component library
repository (gpui-component). An attacker with control over input that
influences logging (e.g., via user-provided data or network inputs in an
application built with this library) could exploit this to inject
arbitrary log messages, polluting logs and potentially obscuring
security events or misleading forensic analysis. Since gpui-component is
a library that integrates with GPUI (which uses tracing for logging),
exploitation would occur in downstream applications that enable logging
and process untrusted inputs, allowing log spoofing without direct code
execution.

exploitation would occur in downstream applications that enable logging
and process untrusted inputs, allowing log spoofing without direct code

```rust
// Proof-of-Concept: Demonstrating log pollution in an application using gpui-component
// This assumes a downstream app (e.g., a GPUI-based GUI app) that uses gpui-component and enables tracing-subscriber for logging.
// The exploit leverages the vulnerability by injecting malicious log messages via controlled input, such as user text fields or network data.
// Prerequisites: The app must have tracing-subscriber configured (common in GPUI apps for debugging), and the attacker needs a way to influence log inputs (e.g., via a text input in the UI).
use gpui_component::{button::Button, input::Input, Component}; // Import from this repository's library
use gpui::{App, Context, WindowOptions}; // GPUI framework
use tracing_subscriber; // Vulnerable dependency (transitive via GPUI)
use tracing::{info, warn}; // For logging
fn main() {
// Initialize tracing-subscriber (vulnerable version from Cargo.lock)
tracing_subscriber::fmt::init();
// Create a simple GPUI app using gpui-component
App::new().run(|cx: &mut App| {
cx.open_window(WindowOptions::default(), |cx| {
let input = cx.new(|cx| Input::new(cx)); // UI component from gpui-component
let button = cx.new(|cx| Button::new("Submit", cx));
// Simulate attacker-controlled input: Malicious payload to pollute logs
// In a real exploit, this could come from user input, network, or file
let malicious_input = "%0A[ATTACKER] Fake security alert: Unauthorized access detected from IP 192.168.1.100%0A"; // Newline injection for log pollution
// When button is clicked, log the input (vulnerable point)
button.on_click(cx, move |_, cx| {
// This logs the input, allowing pollution if input is controlled
info!("User input: {}", malicious_input);
warn!("Processing complete"); // Additional log for context
});
cx.focus(&input);
});
});
}
// To run this PoC:
// 1. Clone the gpui-component repo and build it as a dependency.
// 2. Create a new Rust project with GPUI and this library as deps.
// 3. Add the above code to main.rs.
// 4. Run with `cargo run`.
// 5. Interact with the UI (e.g., click the button) – check logs for injected messages like "[ATTACKER] Fake security alert...".
// Impact: Logs are polluted, potentially hiding real events or creating false positives in monitoring systems.
```
#### Exploitation Impact Assessment
| Impact Category | Severity | Description |
|-----------------|----------|-------------|
| Data Exposure | Low | Logs could be polluted with fake entries,
potentially masking sensitive information leakage if real logs contain
user data or API keys; however, no direct data theft occurs, as
pollution is limited to log output and doesn't expose underlying data
stores in this UI library context. |
| System Compromise | None | No system access is gained; the
vulnerability only allows log message injection, not code execution,
privilege escalation, or control over the application or host system. |
| Operational Impact | Low | Polluted logs could confuse
monitoring/alerting systems, leading to missed security events or false
alarms, but no service disruption, denial-of-service, or resource
exhaustion is possible in this library's isolated UI component usage. |
| Compliance Risk | Low | Could violate logging integrity requirements
in standards like OWASP Top 10 (A09:2021 - Security Logging and
Monitoring Failures) or SOC2 CC7.1 (monitoring), but impact is minimal
for most regulations unless logs are critical for audits in sensitive
apps (e.g., no direct GDPR or HIPAA violations from log pollution
alone). |
