From 86ab799a79d6828e14f43329ed152a98eb6336fd Mon Sep 17 00:00:00 2001 From: "continue[bot]" Date: Tue, 3 Mar 2026 17:13:41 +0000 Subject: [PATCH 1/4] fix(security): Address 3 medium severity security issues 1. XSS via dangerouslySetInnerHTML in ToolsSection.tsx (line 398) - Added DOMPurify.sanitize() to sanitize HTML before rendering 2. Command Injection in TTS sanitization (core/util/tts.ts) - Enhanced sanitizeMessageForTTS() to remove additional shell metacharacters - Added removal of single quotes, brackets, null bytes - Added newline/carriage return replacement - Added message length limit (5000 chars) to prevent DoS 3. Code Execution via new Function() (useChat.imageProcessing.ts) - Replaced unsafe new Function() with standard dynamic import - Added webpackIgnore comment for bundler compatibility Generated with [Continue](https://continue.dev) Co-Authored-By: Continue Co-authored-by: bekah-hawrot-weigel --- core/util/tts.ts | 24 ++++++++++++++----- .../src/ui/hooks/useChat.imageProcessing.ts | 11 +++++---- .../pages/config/sections/ToolsSection.tsx | 3 ++- 3 files changed, 27 insertions(+), 11 deletions(-) diff --git a/core/util/tts.ts b/core/util/tts.ts index aace86bf9dc..0fbb535e8d0 100644 --- a/core/util/tts.ts +++ b/core/util/tts.ts @@ -12,22 +12,34 @@ const ttsKillTimeout: number = 5000; /** * Cleans a message text to safely be used in 'exec' context on host. + * This function sanitizes input to prevent command injection attacks. * * Return modified message text. */ export function sanitizeMessageForTTS(message: string): string { message = removeCodeBlocksAndTrim(message); - // Remove or replace problematic characters + // Remove or replace problematic characters that could enable command injection + // This includes shell metacharacters and escape sequences message = message - .replace(/"/g, "") - .replace(/`/g, "") - .replace(/\$/g, "") - .replace(/\\/g, "") - .replace(/[&|;()<>]/g, ""); + .replace(/"/g, "") // Remove double quotes + .replace(/'/g, "") // Remove single quotes + .replace(/`/g, "") // Remove backticks (command substitution) + .replace(/\$/g, "") // Remove dollar signs (variable expansion) + .replace(/\\/g, "") // Remove backslashes (escape sequences) + .replace(/[&|;()<>{}\[\]!#*?~^]/g, "") // Remove shell metacharacters + .replace(/\x00/g, "") // Remove null bytes + .replace(/\n/g, " ") // Replace newlines with spaces + .replace(/\r/g, " "); // Replace carriage returns with spaces message = message.trim().replace(/\s+/g, " "); + // Limit message length to prevent potential DoS + const MAX_TTS_LENGTH = 5000; + if (message.length > MAX_TTS_LENGTH) { + message = message.substring(0, MAX_TTS_LENGTH); + } + return message; } diff --git a/extensions/cli/src/ui/hooks/useChat.imageProcessing.ts b/extensions/cli/src/ui/hooks/useChat.imageProcessing.ts index 83db7a3cdba..7781ff33887 100644 --- a/extensions/cli/src/ui/hooks/useChat.imageProcessing.ts +++ b/extensions/cli/src/ui/hooks/useChat.imageProcessing.ts @@ -1,13 +1,16 @@ import { logger } from "../../util/logger.js"; /** - * Dynamically import Sharp without using eval + * Dynamically import Sharp module for image processing. + * Uses standard dynamic import which is safe and supported by modern bundlers. */ async function loadSharp(): Promise { try { - // Use Function constructor to avoid bundler issues with dynamic imports - const importSharp = new Function('return import("sharp")'); - const sharpModule = await importSharp().catch(() => null); + // Use standard dynamic import - bundlers like esbuild/webpack handle this correctly + // when configured with external modules or dynamic import support + const sharpModule = await import(/* webpackIgnore: true */ "sharp").catch( + () => null, + ); return sharpModule ? sharpModule.default || sharpModule : null; } catch { return null; diff --git a/gui/src/pages/config/sections/ToolsSection.tsx b/gui/src/pages/config/sections/ToolsSection.tsx index a48bd5df7ac..f439ee67722 100644 --- a/gui/src/pages/config/sections/ToolsSection.tsx +++ b/gui/src/pages/config/sections/ToolsSection.tsx @@ -1,4 +1,5 @@ import { ConfigYaml, parseConfigYaml } from "@continuedev/config-yaml"; +import DOMPurify from "dompurify"; import { ArrowPathIcon, ChevronDownIcon, @@ -395,7 +396,7 @@ function MCPServerPreview({ > ))} From 3b7623a64ee7f58d846252998b2e96da16ea8606 Mon Sep 17 00:00:00 2001 From: "continue[bot]" Date: Tue, 3 Mar 2026 17:18:56 +0000 Subject: [PATCH 2/4] fix(security): Add % to TTS sanitization for cmd.exe variable expansion On Windows, Node.js exec() uses cmd.exe which interprets % for environment variable expansion (e.g., %PATH%, %USERNAME%).
