Summary

CVE-2026-73356 is a missing authorization vulnerability in the Breeze WordPress caching plugin (developed by Cloudways) that allows unauthenticated attackers to delete arbitrary website content. The flaw affects all Breeze versions up to and including 2.5.12 and carries a CVSS v3.1 base score of 8.2 (High). It was fixed in version 2.5.13.

Technical details

  • Root cause: missing authorization (CWE-862) on a plugin function that performs content deletion, allowing the check that should restrict the action to authorized users to be bypassed.
  • Trigger conditions: no authentication or user interaction is required; the attacker only needs network access to the vulnerable WordPress site.
  • Attack vector: network-based (AV:N), low attack complexity, no privileges or user interaction required.
  • Impact: no confidentiality loss, low integrity impact, and high availability impact — consistent with an attacker being able to delete content, disrupting site availability/functionality.

Affected software

  • Breeze (WordPress plugin) by Cloudways, versions up to and including 2.5.12.
  • Fixed in version 2.5.13 and later.

Severity

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

Mitigation and recommended actions

  • Immediate: Update the Breeze WordPress plugin to version 2.5.13 or later.
  • If a patch cannot be applied immediately: consider temporarily deactivating the Breeze plugin, and restrict access to the WordPress admin/plugin endpoints at the network layer (e.g., WAF rules, IP allowlisting) 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.
