Two public API endpoints in `server.js` — `/api/health` and `/api/contact` — were exposed without any rate limiting middleware, allowing attackers to exhaust server resources or spam an SMTP server with unlimited requests. The fix adds rate limiting to both endpoints, with stricter controls on the resource-intensive `/api/contact` route that triggers email sending operations. This change closes a directly exploitable denial-of-service vector in a production web service.
A critical cross-origin message injection vulnerability was discovered in `offscreen.js`, where a wildcard `"*"` origin in `postMessage` calls and a missing source validation check allowed any webpage to send arbitrary messages to the extension's iframe. The fix adds an explicit source check and replaces the wildcard with `"null"` to restrict communication to the trusted iframe only. This change prevents malicious websites from hijacking the extension's offscreen message channel.
A command injection vulnerability was discovered in `scripts/check-publish-status.js` where the `version` parameter was interpolated directly into shell commands via `execSync`. By switching to `execFileSync` with argument arrays, the fix eliminates shell interpretation entirely, preventing any attacker-controlled input from being executed as shell commands.
CVE-2026-41680 is a high-severity Denial of Service vulnerability in the marked Markdown parsing library, affecting versions prior to 18.0.2. By supplying a crafted input sequence to the parser, an attacker can cause the application to hang or exhaust resources, making the frontend unavailable. Upgrading marked from 18.0.0 to 18.0.2 in both `package.json` and `package-lock.json` closes the vulnerability without affecting valid Markdown rendering.
CVE-2026-4800 is a high-severity arbitrary code execution vulnerability in lodash-es versions prior to 4.18.0, triggered through untrusted input passed to lodash's template engine. The fix upgrades lodash-es from 4.17.23 to 4.18.1 using a pnpm override, ensuring all transitive dependents pick up the patched version. This is a concrete reminder that even utility libraries like lodash can become critical attack surfaces when they process user-controlled input.
A high-severity denial-of-service vulnerability in js-yaml (GHSA-5p4m-2wfm-xmqj) caused quadratic CPU consumption when resolving `!!omap` YAML types in both the 3.x and 4.x branches. The fix upgrades js-yaml from 3.14.2 to 3.15.1 and from 4.1.1 to 4.3.1, eliminating the algorithmic complexity exploit while leaving all valid YAML inputs unaffected.
A critical vulnerability in `agent/src/updater.js` allowed an attacker who could modify the agent's configuration to redirect software update downloads to an attacker-controlled server, enabling remote code execution via a crafted tarball. The fix introduces strict hostname validation — including private network awareness — so the updater only fetches from trusted origins. This kind of supply-chain attack vector is easy to overlook but catastrophic in production agent deployments.
CVE-2025-58754 is a high-severity Denial of Service vulnerability in the popular axios HTTP client library, caused by the absence of a data size check on incoming response or request payloads. An attacker who can influence the size of data processed by axios could exhaust server memory or CPU, bringing down dependent Node.js applications. The fix upgrades axios from version 1.8.4 to 1.18.0, closing the unbounded data processing path.
A high-severity denial-of-service vulnerability (CVE-2025-14874) in Nodemailer versions prior to 7.0.0 allowed attackers to crash Node.js email-sending services by supplying specially crafted email address headers. The fix upgrades the `nodemailer` dependency in `clay-server` from version 6.10.1 to 9.0.5, closing the attack surface against malformed input. Any application that passes user-influenced data into Nodemailer's address parsing logic is affected and should upgrade immediately.
CVE-2024-4068 is a high-severity Regular Expression Denial of Service (ReDoS) vulnerability in the `braces` npm package (versions prior to 3.0.3) that allows an attacker to trigger catastrophic CPU consumption by supplying a crafted brace-expansion string with no character limit. The fix upgrades `braces` from 3.0.2 to 3.0.3 and its internal dependency `fill-range` from 7.0.1 to 7.1.1, both of which enforce limits on the size of input they will process. This patch was applied via a Yarn resoluti
A high-severity command injection vulnerability was discovered in `Config/QuickAdd/git-add-new-origin-branch.js`, where user-supplied branch names were interpolated directly into a shell command string passed to `child_process.exec()`. The fix replaces the shell-interpolated `exec()` call with `execFile()`, passing arguments as a discrete array and eliminating the shell entirely. This proactive hardening removes an exploit primitive that could have been chained with other weaknesses to achieve a
A command injection vulnerability in `sitrecServer/windProxy.php` allowed user-controlled input to reach a shell command without proper sanitization, creating a remote code execution risk. The `$cycleHour` parameter was passed directly as a format integer (`%d`) into a `sprintf`-built shell command, bypassing the `escapeshellarg()` protection applied to all other arguments. The fix casts `$cycleHour` to an integer and wraps it with `escapeshellarg()`, closing the injection path entirely.
