This is a critical security maintenance release for the v0.x branch. It addresses a high-priority vulnerability involving prototype pollution that could lead to a Denial of Service (DoS).

Recommendation: All users currently on the 0.x release line should upgrade to this version immediately to ensure environment stability.

🛡️ Security Fixes

• Backport: Fix DoS via proto key in merge config
  • Patched a vulnerability where specifically crafted configuration objects using the proto key could cause a Denial of Service during the merge process. - by @FeBe95 in PR #7388

⚙️ Maintenance & CI

• CI Infrastructure Update
  • Updated Continuous Integration workflows for the v0.x branch to maintain long-term support and build reliability. - by @jasonsaayman in PR #7407

⚠️ Breaking Changes

Configuration Merging Behavior:

As part of the security fix, Axios now restricts the merging of the proto key within configuration objects. If your codebase relies on unconventional deep-merging patterns that target the object prototype via Axios config, those operations will now be blocked. This is a necessary change to prevent prototype pollution.
