From e5b23eb7c0670b4814dd57ef19cfc28fe24e4a09 Mon Sep 17 00:00:00 2001 From: Markus Hartung Date: Wed, 19 Aug 2026 09:07:35 -0300 Subject: [PATCH 1/4] fix(security): zero out open CodeQL code-scanning alerts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - src/mitm/handlers/antigravity.ts: fix broken \s regex escape in a template-string RegExp (unrecognized escape silently dropped the backslash, breaking the whitespace match) — also clears the two useless-regexp-character-escape alerts. - open-sse/executors/gemini-web.ts: replace the unbounded polynomial regex in isMissingBrowserExecutable() with plain substring checks. - src/shared/middleware/chatBodyAdmission.ts, open-sse/services/ conversationTracker.ts, src/app/api/v1/models/catalogCache.ts: annotate the sha256 fingerprint hashes (admission-budget key, conversation identity, catalog memo key — none are password/ credential hashes) with codeql[js/insufficient-password-hash] suppressions; the existing suppression comments in chatBodyAdmission.ts were on the wrong line and CodeQL never picked them up. - tests/unit/qwen-token-plan-console-site.test.ts, tests/unit/ cloudflare-playground-provider.test.ts: replace raw string.includes(hostname) assertions with new URL(...).hostname equality/endsWith checks, closing the incomplete-url-substring- sanitization alerts without weakening what the tests verify. --- open-sse/executors/gemini-web.ts | 8 ++++++-- open-sse/services/conversationTracker.ts | 2 +- src/app/api/v1/models/catalogCache.ts | 2 +- src/mitm/handlers/antigravity.ts | 5 ++++- src/shared/middleware/chatBodyAdmission.ts | 9 +++------ tests/unit/cloudflare-playground-provider.test.ts | 3 ++- tests/unit/qwen-token-plan-console-site.test.ts | 13 +++++++------ 7 files changed, 24 insertions(+), 18 deletions(-) diff --git a/open-sse/executors/gemini-web.ts b/open-sse/executors/gemini-web.ts index 3ae6df79cd5f..18dd7af008ad 100644 --- a/open-sse/executors/gemini-web.ts +++ b/open-sse/executors/gemini-web.ts @@ -34,8 +34,12 @@ const GEMINI_URL = "https://gemini.google.com/app"; */ export function isMissingBrowserExecutable(message: string): boolean { if (!message) return false; - return /executable doesn't exist|executablenotfound|playwright install|chromium.*download/i.test( - message + const lower = message.toLowerCase(); + return ( + lower.includes("executable doesn't exist") || + lower.includes("executablenotfound") || + lower.includes("playwright install") || + (lower.includes("chromium") && lower.includes("download")) ); } const GEMINI_USER_AGENT = diff --git a/open-sse/services/conversationTracker.ts b/open-sse/services/conversationTracker.ts index cd70593fd2c6..869afdec21bb 100644 --- a/open-sse/services/conversationTracker.ts +++ b/open-sse/services/conversationTracker.ts @@ -201,7 +201,7 @@ export function extractCanonicalTurns(body: JsonRecord | null | undefined): Cano // ── Fingerprint (identity, O(1) regardless of history size) ───────────── function hashHex(text: string): string { - return createHash("sha256").update(text).digest("hex"); + return createHash("sha256").update(text).digest("hex"); // codeql[js/insufficient-password-hash] — content fingerprint for conversation identity, not a password/credential hash } function extractToolNames(body: JsonRecord | null | undefined): string[] { diff --git a/src/app/api/v1/models/catalogCache.ts b/src/app/api/v1/models/catalogCache.ts index 59eed06f51f6..2a370184b0c3 100644 --- a/src/app/api/v1/models/catalogCache.ts +++ b/src/app/api/v1/models/catalogCache.ts @@ -22,7 +22,7 @@ import { isCodexModelCatalogClient } from "./catalogRequest"; /** Fingerprint an API key for the catalog memo Map.
