Summary

CVE-2026-73350 is a broken authentication vulnerability affecting the SupportCandy WordPress plugin (developed by PSM Plugins) in versions up to and including 3.5.1. The flaw stems from incorrect privilege assignment and allows a remote, unauthenticated attacker to bypass authentication controls over the network. It carries a CVSS v3.1 base score of 8.2 (High).

Technical details

  • Root cause: Incorrect privilege assignment (CWE-266) within the plugin’s authentication handling logic, resulting in broken authentication.
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw; exploitation is possible over the network with low attack complexity.
  • Attack vector: Network (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N).
  • Impact: High confidentiality impact and low integrity impact, with no impact to availability — consistent with an attacker being able to bypass authentication and gain unauthorized access to sensitive data or functionality without needing valid credentials.

Affected software

  • SupportCandy WordPress plugin, versions up to and including 3.5.1
  • Fixed in version 3.5.2

Severity

  • CVSS v3.1 Base Score: 8.2 (High)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N

Mitigation and recommended actions

  • Immediate: Update the SupportCandy plugin to version 3.5.2 or later, which addresses this vulnerability, as soon as possible.
  • If patching cannot be applied immediately: Restrict or monitor external access to the WordPress site and the SupportCandy support-ticket interface, review site logs for unusual or unauthenticated access to plugin endpoints, and consider temporarily deactivating the plugin until the update can be applied.

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.
