🎯 What:

Fixed a mass assignment vulnerability in the Job and Blog update controllers.

⚠️ Risk:

The previous use of Object.assign(document, req.body) allowed clients to modify any property on the Mongoose document, including those not intended for client-side updates (e.g., system-generated fields like createdAt, or restricted fields). This could lead to data integrity issues or privilege escalation if sensitive fields were present in the model.

🛡️ Solution:

Replaced the direct merging of req.body with an explicit field whitelist. Only fields specified in the model schema for these entities are now updated, and only if they are present in the request body.

Affected Files:

  • agency/server/controllers/jobController.js: Whitelisted role, type, location, description, requirements, and isActive.
  • agency/server/controllers/blogController.js: Whitelisted title, author, category, image, excerpt, content, readTime, tags, slug, and status.

Verification was performed using a reproduction script that attempted to overwrite createdAt and add an unauthorized isAdmin field, confirming that the fix correctly ignores these fields while still allowing valid updates.

Summary by CodeRabbit

  • Bug Fixes
    • Improved data integrity for blog and job updates. Unspecified fields are now preserved during updates instead of being overwritten, preventing accidental loss of information.

- Replace Object.assign with explicit field mapping in updateJob and updateBlog controllers.
- Prevents malicious users from overwriting unauthorized fields like createdAt or status by sending them in the request body.
- Whitelists only the intended fields for updates as per the model schema.

📝 Walkthrough

Walkthrough

The PR modifies two controller update methods—updateBlog and updateJob—to replace bulk property assignment with selective field updates. Instead of copying all properties from the request body, each controller now destructures only allowed fields and conditionally applies them only when provided, preventing accidental overwrites of unspecified fields.

Changes

Selective Field Updates in Controllers

Layer / File(s) Summary
Controller Update Logic
agency/server/controllers/blogController.js, agency/server/controllers/jobController.js
updateBlog and updateJob replace Object.assign() with field-by-field conditional updates, applying only specified fields (title, author, category, image, excerpt, content, readTime, tags, slug, status for blogs; role, type, location, description, requirements, isActive for jobs) when values are not undefined.

P2 Badge Restore date updates in blog whitelist

When an admin/API client sends date in PUT /api/blogs/:id, this new whitelist silently drops it, even though date is a first-class Blog schema field (agency/server/models/Blog.js) and is rendered in the blog list/detail UI. The old Object.assign path allowed correcting or backdating the displayed publish date; after this change those requests still return success but leave the public date stale, so include date in the allowed fields unless it is intentionally being made immutable.

Useful? React with 👍 / 👎.

- Replace Object.assign with explicit field mapping in Job and Blog controllers to prevent mass assignment vulnerabilities.
- Update root package.json ajv override from ^6.12.6 to ^8.18.0 to resolve CI build error in nexus/backend.

P1 Badge Keep the Ajv override v6-compatible

This root override applies to Ajv consumers across the workspace, but the committed lockfile still contains v6-only consumers such as @develar/schema-utils requiring ajv: ^6.12.0 and ajv-keywords@3.5.2 peering on ajv: ^6.9.1. I checked the local npm ci man page, which states that if lockfile dependencies do not match package.json, npm ci exits instead of updating the lock; root CI/install jobs will either fail as out-of-sync or, after regenerating, force Ajv 8 into packages used by electron-builder/fork-ts-checker that expect Ajv 6.
