A high-severity prototype pollution vulnerability (CVE-2026-35209) was discovered in the `defu` package version 6.1.4, which allowed attackers to inject properties into JavaScript's `Object.prototype` via the `__proto__` key in defaults arguments. The fix upgrades `defu` to version 6.1.5 in the frontend's dependency tree, protecting downstream consumers like `c12` and `dotenv` configuration loaders from malicious property injection.
A missing `cooldown` block in `.github/dependabot.yml` meant that newly published packages — which could be malicious or unstable — were eligible for immediate update proposals. By adding a `cooldown` block with `default-days: 7` to both the GitHub Actions and Cargo package ecosystems, the project now enforces a 7-day waiting period before Dependabot proposes any update to a freshly released package version. This change significantly reduces the risk of dependency confusion attacks and supply ch
A high-severity supply chain vulnerability was discovered in `.github/dependabot.yml` where missing cooldown periods allowed Dependabot to immediately propose updates for newly published packages. This configuration flaw exposed the CI/CD pipeline to malicious or unstable package versions. The fix adds a 7-day cooldown period to both pip and GitHub Actions ecosystems, creating a safety window for the community to identify compromised packages before they enter the codebase.
A high-severity configuration gap was discovered in a Node.js library's `.github/dependabot.yml` file where no cooldown period was set for dependency updates. This meant Dependabot could immediately propose updates to newly published (and potentially malicious) package versions, exposing the project and all downstream consumers to supply chain attacks. The fix adds a `cooldown` block with `default-days: 7` to both the `npm` and `github-actions` package ecosystem entries.
A high-severity supply chain vulnerability was discovered in a `.github/dependabot.yml` configuration that lacked a cooldown period, meaning Dependabot could immediately propose updates to newly published (and potentially malicious) package versions. The fix adds a `cooldown` block with `default-days: 7` to enforce a 7-day waiting period before suggesting updates, giving the community time to detect and flag compromised packages.
A high-severity supply chain vulnerability was discovered in a `.github/dependabot.yml` configuration file that lacked a cooldown period for package updates. Without a cooldown, Dependabot could immediately propose updates to newly published—and potentially malicious—package versions. The fix adds a 7-day `cooldown` block to both the npm and github-actions ecosystem entries, giving the community time to identify and flag compromised packages before they're adopted.
A critical vulnerability in the DragonFly installation script allowed attackers to inject malicious packages by downloading and installing software without verifying integrity checksums. The fix adds SHA256 verification before installation, ensuring only legitimate packages are executed with elevated privileges.
CVE-2024-27308 is a high-severity vulnerability in the Rust `mio` crate (versions prior to 0.8.11) that exposes a race condition in named pipe I/O event handling on Windows. The fix upgrades `mio` from version 0.8.10 to 0.8.11, closing the window for potential exploitation in applications like `rpm-ostree` that depend on async I/O. Because `mio` sits at the foundation of the Tokio async runtime, this flaw has wide blast radius across the Rust ecosystem.
A critical shell injection vulnerability in `scripts/mkmultidtb.py` allowed attackers to execute arbitrary commands during the kernel build process by injecting shell metacharacters into device tree binary (DTB) filenames. The vulnerability was caused by using `os.system()` with string concatenation instead of proper subprocess argument handling. This fix migrates to `subprocess.run()` with argument lists, eliminating the attack surface entirely.
CVE-2026-35209 is a high-severity prototype pollution vulnerability in the `defu` JavaScript library (versions prior to 6.1.5) that allows attackers to inject arbitrary properties onto `Object.prototype` by passing a `__proto__` key in the defaults argument. The vulnerability was present in the `blog-site` project's dependency tree and was resolved by upgrading `defu` to 6.1.5 and adding an explicit `overrides` entry to prevent transitive re-introduction of the vulnerable version.
A high-severity vulnerability (CVE-2026-41676) was discovered in the `rust-openssl` crate (version 0.10.73) used in the `apps/rust-sdk` component, as flagged by the Trivy scanner in `Cargo.lock`. The fix upgrades the `openssl` crate from `0.10.73` to `0.10.80` and `openssl-sys` from `0.9.109` to `0.9.116`, closing an exploitable attack surface in production code that handles user-influenced input. Because the Rust SDK sits in the production codebase, any attacker able to reach the OpenSSL code p
CVE-2021-29937 is a critical memory safety vulnerability in the Rust `telemetry` crate (versions prior to 0.1.3) that allows freeing uninitialized memory, leading to undefined behavior, potential crashes, and possible code execution. The fix involves upgrading the crate from version 0.1.0 to 0.1.3, which patches the unsafe memory handling at the root cause. Despite Rust's reputation for memory safety, this vulnerability demonstrates that `unsafe` code blocks can still introduce serious bugs that
