CRLF Injection

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to CRLF Injection in the parseSetCookie. An attacker can inject arbitrary HTTP headers by supplying specially crafted percent-encoded values in the Set-Cookie header, which are improperly decoded and then forwarded into response headers. This can enable actions such as session fixation, open redirect, or cache poisoning.

Note: This is only exploitable if the application parses Set-Cookie headers using the affected function and then forwards the parsed value into a response header without proper sanitization.

Workaround

This vulnerability can be mitigated by sanitizing the values returned by the affected cookie parsing functions to strip or reject CR, LF, NUL, ;, and = bytes before forwarding them into response headers.

Remediation

Upgrade undici to version 6.27.0, 7.28.0, 8.5.0 or higher.

Allocation of Resources Without Limits or Throttling

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the handling of WebSocket message fragments. An attacker can cause unbounded memory growth and exhaust system resources by streaming a large number of small or empty continuation frames from a malicious WebSocket server.

Remediation

Upgrade undici to version 6.26.0, 7.28.0, 8.5.0 or higher.

Improper Handling of Highly Compressed Data (Data Amplification)

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) in the PerMessageDeflate.decompress() method of the permessage-deflate extension. An attacker can cause excessive memory usage by sending specially crafted compressed WebSocket frames that decompress to a very large size, potentially leading to process crashes or unresponsiveness.

Remediation

Upgrade undici to version 6.24.0, 7.24.0 or higher.

Uncaught Exception

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Uncaught Exception through improper validation of the server_max_window_bits parameter in the permessage-deflate extension. An attacker can cause the process to terminate unexpectedly by sending a maliciously crafted value outside the valid range, which triggers an unhandled exception when the client attempts to create a zlib InflateRaw instance.

Remediation

Upgrade undici to version 6.24.0, 7.24.0 or higher.

Permissive List of Allowed Inputs

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Permissive List of Allowed Inputs via permissive substring matching in the Set-Cookie attribute parsing. An attacker can weaken cookie SameSite enforcement by crafting a response with a non-standard SameSite value that is interpreted as a more permissive setting, potentially allowing cookies to be sent in cross-site requests.

Note: This is only exploitable if the application consumes Set-Cookie headers from server responses (for example via undici's fetch or proxy code paths) and then forwards or relies on the parsed sameSite attribute.

Workaround

This vulnerability can be mitigated by validating that the parsed sameSite attribute is exactly 'Strict', 'Lax', or 'None' (case-insensitive) before relying on or forwarding it.

Remediation

Upgrade undici to version 6.27.0, 7.28.0, 8.5.0 or higher.

HTTP Request Smuggling

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to HTTP Request Smuggling in the processHeader() while handling HTTP/1.1 requests containing duplicate Content-Length headers with differing casing. An attacker can bypass access controls, poison caches, hijack credentials, or cause service disruption by sending specially crafted HTTP requests that are interpreted inconsistently by proxies and backend servers.

Remediation

Upgrade undici to version 6.24.0, 7.24.0 or higher.

Time-of-check Time-of-use (TOCTOU) Race Condition

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition in the HTTP/1.1 client when an attacker-controlled upstream server injects an unsolicited response onto an idle keep-alive socket after a request completes. An attacker can cause responses to be delivered to the wrong requests by sending crafted HTTP responses through a compromised or malicious upstream server.

Note: This is only exploitable if the upstream HTTP/1.1 server is attacker-controlled or compromised and keep-alive connection reuse is enabled.

Workaround

This vulnerability can be mitigated by disabling keep-alive connection reuse by setting keepAliveTimeout: 0 on the Client or Pool.

Remediation

Upgrade undici to version 6.27.0, 7.28.0, 8.5.0 or higher.

  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the decompression chain. An attacker can cause high CPU usage and excessive memory allocation by sending HTTP responses with a large number of chained compression steps in the Content-Encoding header.

Remediation

CRLF Injection

  • Vulnerable module: undici
  • Introduced through: @actions/core@1.11.1

Detailed paths

  • Introduced through: open-ai-reviewer@PierreGode/GPTcode-reviwer › @actions/core@1.11.1 › @actions/http-client@2.2.3 › undici@5.29.0
    Remediation: Upgrade to @actions/core@2.0.0.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to CRLF Injection via the upgrade option of the client.request() function. An attacker can inject malicious data into HTTP headers or prematurely terminate HTTP requests by sending specially crafted input, potentially leading to unauthorized information disclosure or bypassing of security controls.
