CVE-2025-31833: JobBoard Job Listing Auth Bypass Vulnerability

CVE-2025-31833 is an authorization bypass flaw in JobBoard Job listing plugin that allows attackers to exploit misconfigured access controls through user-controlled keys. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2025-31833 Overview

CVE-2025-31833 is an Authorization Bypass Through User-Controlled Key vulnerability in the themeglow JobBoard Job listing WordPress plugin (job-board-light). The flaw is classified as an Insecure Direct Object Reference (IDOR) and tracks to [CWE-639]. It affects all plugin versions up to and including 1.2.8.

The vulnerability lets an authenticated attacker with high privileges manipulate user-controlled identifiers to access or modify records belonging to other users. Successful exploitation targets integrity, with no confidentiality or availability impact per the published CVSS vector.

Critical Impact

Attackers can modify resources belonging to other users by tampering with object identifiers in requests handled by the plugin.

Affected Products

  • themeglow JobBoard Job listing (job-board-light) WordPress plugin
  • All versions from n/a through <= 1.2.8
  • WordPress sites running the vulnerable plugin build

Technical Details for CVE-2025-31833

Vulnerability Analysis

The plugin exposes endpoints that accept object identifiers supplied by the client without verifying that the authenticated user owns or is authorized to act on the referenced resource. This is a textbook Insecure Direct Object Reference pattern. An attacker who already holds an authenticated session can substitute identifiers in request parameters to reach records belonging to other accounts.

Because the access decision relies on a user-controlled key rather than a server-side authorization check, the plugin treats any supplied identifier as valid. The resulting operations can alter data integrity across tenants within the same WordPress installation. The CVSS vector indicates network-reachable exploitation requiring high privileges, with impact limited to integrity.

Root Cause

The root cause is missing authorization enforcement at the data-access layer. Request handlers in job-board-light fetch and mutate records keyed by identifiers passed in request parameters, without cross-checking those identifiers against the current user's ownership or role.

Attack Vector

Exploitation proceeds over HTTP(S) against the WordPress site hosting the plugin. The attacker must first authenticate with a high-privilege account recognized by the plugin's workflow. They then issue a request to an affected plugin endpoint and substitute a numeric or string identifier that references another user's object. The server performs the requested action against the targeted record without rejecting the mismatched owner.

No verified public exploit code is available. Technical details are documented in the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-31833

Indicators of Compromise

  • Unexpected modifications to job listing records, applications, or user profile data not initiated by the record owner
  • WordPress access logs showing authenticated requests to job-board-light endpoints with sequentially iterated id parameters
  • Audit-log entries where the acting user differs from the resource owner for plugin-managed objects

Detection Strategies

  • Review WordPress and web server logs for authenticated POST or GET requests to plugin endpoints containing identifier parameters that do not match the session user
  • Correlate plugin database writes with the authenticated user ID to flag ownership mismatches
  • Enable WordPress audit logging to capture create, update, and delete events against plugin-managed tables

Monitoring Recommendations

  • Alert on high-privilege accounts issuing bursts of requests that iterate object identifiers against job-board-light endpoints
  • Monitor for anomalous administrative or editor-level activity outside normal business hours
  • Track changes to the plugin's database tables and compare the modifying user against the record owner field

How to Mitigate CVE-2025-31833

Immediate Actions Required

  • Identify all WordPress installations running job-board-light version 1.2.8 or earlier
  • Restrict high-privilege plugin roles to trusted administrators until a fixed release is deployed
  • Audit recent changes to job listings and related records for unauthorized modifications

Patch Information

At the time of the NVD entry, the advisory lists affected versions through <= 1.2.8 with no fixed version specified. Monitor the vendor's plugin page and the Patchstack Vulnerability Report for a patched release and upgrade immediately when available.

Workarounds

  • Temporarily deactivate the job-board-light plugin until a vendor patch is released
  • Place the WordPress admin area behind a web application firewall rule that validates identifier parameters against the authenticated session
  • Limit the number of users granted the high-privilege role required to reach the vulnerable endpoints
