LDAP Filter Injection in da_unique_email_validator Fixed

The registration-time email uniqueness validator, `da_unique_email_validator`, formatted the submitted email address straight into an LDAP search filter with Python's `%` operator, so filter metacharacters in the email were interpreted as filter syntax. The fix wraps the value in `ldap.filter.escape_filter_chars()` (and imports the `ldap.filter` submodule explicitly), so a submitted address is always treated as a literal attribute value. Any deployment with `ldap login` enabled and a bind accoun

ExternalHttpClient::request() Sent Basic Auth Over Plain HTTP

The `ExternalHttpClient::request()` helper accepted a `$basicAuth` string and passed it straight to the HTTP client's `auth` option without checking that the target URL used `https://`. Any external JSON data source configured with an `http://` endpoint therefore shipped a base64-encoded `Authorization: Basic` header in cleartext on every scheduled load. The fix rejects the request outright — before a client is even created — when the URL scheme is not HTTPS.

modelExporter.js Path Traversal via Unsanitized Directory Concatenation

A path traversal vulnerability in `modelExporter.js` allowed attackers to read arbitrary files by injecting traversal sequences into directory and relative path parameters. The `readSourceFile` function concatenated these unsanitized inputs directly into file URLs passed to `fetch()`. The fix introduces strict path normalization that rejects attempts to escape the intended directory.

SQL's Insert() and Update() Methods Used F-String Interpolation in u2share_batch_give_sugar

The SQL helper class in u2share_batch_give_sugar used Python f-strings to construct INSERT and UPDATE queries, creating SQL injection vulnerabilities even though values appeared to come from internal constants. The fix replaces all f-string query construction with sqlite3 parameterized queries using `?` placeholders, eliminating string interpolation entirely from the database path.

installPlugin(): Unvalidated npm Package Names Reach npm install

A plugin manager service exposed an `installPlugin(plugin: PluginInfo)` method that passed `plugin.packageName` and `plugin.version` straight into the platform's npm install routine with no validation, no blocklist, and no integrity verification of the fetched tarball. Because npm treats a non-semver "version" as a fetch specifier — a tarball URL, a git ref, a local path — an attacker who could influence the plugin listing could get arbitrary code installed and executed with full Electron/Node p

deleteNestedProperty Prototype Pollution via Dot-Notation Path

The `deleteNestedProperty` function in propertyUtils.ts allowed attackers to manipulate JavaScript object prototypes by passing specially crafted dot-notation paths like `__proto__.polluted`. A fix now blocks dangerous keys before processing, preventing prototype pollution attacks that could affect all objects in the application.

TrackOptionsManager DDL: Template-Literal SQL Injection Closed

The `TrackOptionsManager` service built its `CREATE TABLE` and `ALTER TABLE ... ADD COLUMN alias` statements by interpolating a `DEFAULT_ALIAS` constant directly inside single quotes in a JavaScript template literal, and its private `_query()` helper had no parameter channel at all. The fix routes the default value through `mysql.escape()` and gives `_query(q, params = [])` a real bound-parameter argument that is forwarded to `db.query()`. This removes an injection primitive on a schema-bootstra

eval() in Async Function Constructor Enables Runtime Escape

The eval.mjs command handler used raw `eval()` to execute JavaScript expressions, creating a critical code injection path if owner credentials are compromised. The fix replaces `eval()` with the `AsyncFunction` constructor and explicitly shadows `process`, `require`, and other runtime globals as parameters, preventing evaluated code from reaching the Node.js runtime even when authentication boundaries fail.

How SQL injection via template literals happens in Node.js SQLite and how to fix it

A SQL injection vulnerability in `src/lib/codex-state.mjs` allowed dynamic column names to reach SQL queries through JavaScript template literals. The fix implements defense-in-depth with strict identifier validation using `SAFE_IDENTIFIER` regex before query construction.

How stored XSS happens in TinyMCE plugins and how to fix it

The snippets plugin's `Main.ts` inserted raw, unsanitized snippet content directly into the TinyMCE editor via `editor.insertContent(snippet.content)`, allowing stored JavaScript payloads saved by any snippet editor to execute in every user's browser. The fix routes snippet content through TinyMCE's own parser and serializer before insertion, stripping dangerous markup while preserving legitimate formatting.

How credential leakage through console logging happens in JavaScript browser extensions and how to fix it

A browser extension's `src/background/credentials.js` printed the full Strava authentication cookie string — including a signed JWT and CloudFront-Signature values — straight into the extension console via `console.debug`. Anyone who could open DevTools on the background page (or any tooling that scraped the console) could copy a live session and impersonate the user. The fix replaces the credential payload in both log statements with `Boolean(credentials)` and strips a realistic-looking JWT out

How CSS Injection via Weak Pattern Validation happens in Vue.js and how to fix it

A critical CSS injection vulnerability in `testpage/App.vue` allowed attackers to bypass weak HTML5 pattern validation and load malicious stylesheets. The fix replaces direct variable assignment with a hardened `setCustomStylesheetHref()` method using strict regex validation.
