Security vulnerabilities and automated fixes for supply chain issues

A high-severity configuration vulnerability was discovered in a `.github/dependabot.yml` file that lacked a cooldown period for package updates. Without this safeguard, Dependabot could immediately propose updates to newly published package versions—including potentially malicious or unstable releases. The fix adds a simple `cooldown` block with a 7-day waiting period before any new package version is suggested.
TrafficMonitor's software update mechanism in `UpdateHelper.cpp` fetched and parsed update manifests from remote servers without validating the version string or enforcing trusted download URLs, leaving users exposed to man-in-the-middle (MITM) attacks. An attacker on the same network could intercept the update channel and inject a malicious binary under a crafted version string or an HTTP download link pointing to attacker-controlled infrastructure. The fix adds strict version-string sanitizati
A high-severity supply chain vulnerability was discovered in a Dependabot configuration file that lacked cooldown periods for package updates. Without cooldown settings, Dependabot could propose updates to newly published—and potentially malicious—packages immediately after release. The fix adds a 7-day cooldown period to all three package ecosystems (npm, GitHub Actions, and Maven), giving the community time to identify compromised packages before they're automatically proposed.
A medium-to-high severity vulnerability was discovered and patched in Slidev's resolver module, where dynamically loaded theme and plugin packages specified in slide frontmatter lacked proper validation, allowing a malicious package name to execute arbitrary code with the developer's full OS privileges. This fix addresses a supply-chain-adjacent attack vector that could allow attackers to exfiltrate credentials or compromise developer machines simply by sharing a crafted markdown presentation fi
A high-severity vulnerability in `graphify/hooks.py` allowed attackers to achieve arbitrary code execution on CI/CD runners by injecting malicious hook script paths through a user-controlled configuration file. The fix introduces strict path validation against an allowlist of permitted directories before any subprocess execution. This kind of supply-chain attack vector is increasingly common and can silently compromise entire build pipelines with a single malicious commit.
