Summary

CVE-2026-14943 is an information exposure vulnerability (CWE-200) in the "Password Protected — Lock Entire Site, Pages, Posts, Categories, and Partial Content" WordPress plugin. When a specific option is enabled, the plugin fails to restrict REST API access, letting unauthenticated attackers bypass the sitewide password gate and read protected content and account identifiers. It is rated High severity (CVSS 7.5).

Technical details

  • Root cause: The plugin does not properly restrict REST API access to authenticated users when a particular option is enabled, leaving protected data reachable through the REST API.
  • Trigger conditions: The vulnerable configuration option must be enabled on the site.
  • Attack vector: Network — remote, unauthenticated requests to the WordPress REST API, requiring no privileges and no user interaction.
  • Impact: Bypass of the sitewide password protection, disclosing otherwise-protected content and user account identifiers (confidentiality impact only; no integrity or availability impact).
  • Note: This is a regression of the previously patched CVE-2024-0437, fixed in 2.6.7 and reintroduced in 2.6.8.

Affected software

  • Password Protected — Lock Entire Site, Pages, Posts, Categories, and Partial Content: versions 2.6.8 up to and including 2.8.3 (all versions before 2.8.4).
  • Fixed in version 2.8.4.

Severity

  • CVSS v3.1 base score: 7.5 (High)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Upgrade the plugin to version 2.8.4 or later.
  • If no patch can be applied: Disable the plugin option that exposes REST API access until the update is installed, and restrict or filter unauthenticated access to the WordPress REST API at the network or web-server layer.

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.
