CVE-2026-54186 – Unauthenticated SQL Injection – EyeCix JobSearch WordPress Plugin ≤ 3.2.9

Be the first to know when new zero-days emerge:

Summary

CVE-2026-54186 is a critical unauthenticated SQL injection vulnerability (CWE-89) in the eyecix JobSearch WP Job Board WordPress plugin, affecting all versions up to and including 3.2.9. With a CVSS v3.1 base score of 9.3 (Critical) and a Scope:Changed metric, any anonymous attacker able to reach an affected site can directly interact with the underlying database — no credentials or user interaction required. The fixed version, 3.3.0, was released to address this flaw and immediate upgrade is strongly recommended.

Technical details

  • Root cause: Improper neutralization of special elements in SQL commands (CWE-89), allowing unsanitized attacker-controlled input to be incorporated directly into database queries.
  • Trigger conditions: No authentication, no user interaction, and no elevated privileges are required — any anonymous network request to the vulnerable endpoint is sufficient to trigger the injection.
  • Attack vector: Network (AV:N), with low attack complexity (AC:L); the vulnerability is exploitable remotely over the internet against any publicly reachable WordPress installation running the affected plugin version.
  • Impact: The Scope:Changed (S:C) metric indicates the SQL injection can reach database content outside the plugin’s own context — including WordPress core tables containing user credentials, session tokens, and PII. Confidentiality impact is rated High (C:H), with low availability impact (A:L) and no integrity impact.

Affected software

  • eyecix JobSearch WP Job Board (WordPress plugin: wp-jobsearch), all versions ≤ 3.2.9

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

Mitigation and recommended actions

  • Immediate: Update the wp-jobsearch plugin to version 3.3.0 or later, which contains the vendor-provided fix.
  • If immediate patching is not possible: Restrict public access to the WordPress installation at the network or web application firewall (WAF) level until the patch can be applied. A virtual patching/mitigation rule is available through Patchstack for subscribers to block exploitation attempts pending the upgrade.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
