Attack Vectors

CVE-2026-28036 is a Medium-severity Server-Side Request Forgery (SSRF) issue (CVSS 6.4) affecting the Restaurant WordPress Theme | Ratatouille theme (slug: ratatouille) in versions up to and including 1.2.6.

The key exposure is that an attacker needs only an authenticated WordPress account with Subscriber-level access or higher to trigger the behavior. In practical terms, this means organizations with open registration, large user bases, membership features, loyalty programs, or frequent account creation are at higher risk because the pool of eligible accounts is bigger.

SSRF allows requests to be made from your website/server to other locations. That can include external destinations on the internet and, critically, internal services that are not normally reachable from the outside.

Security Weakness

This vulnerability exists because the theme can be induced to make web requests to arbitrary locations originating from the WordPress application itself. When request destinations are not strictly constrained (for example, to an approved allowlist), attackers can redirect the server to “phone home” to targets the attacker chooses.

According to the published advisory, this SSRF condition can be used to query and modify information from internal services. While the CVSS vector indicates limited confidentiality and integrity impact (C:L/I:L) and no direct availability impact (A:N), the presence of SSRF is often a stepping-stone to broader compromise depending on what internal endpoints and cloud services your server can reach.

There is no known patch available at this time. As a result, mitigation decisions should be made based on risk tolerance and business exposure, and may include replacing the affected theme.

Technical or Business Impacts

For business owners and marketing leaders, the practical risk is not “a theme bug” in isolation, but what it can enable: attackers may be able to use your WordPress site as a launching point to access or manipulate internal services that were never intended to be reachable from the public internet.

Potential impacts include data exposure (customer/contact information, internal content, operational details), unauthorized changes to internal resources reachable by the server, and compliance and reporting burden if sensitive data is accessed. Even if the immediate severity is Medium, incident response costs and brand trust damage can be disproportionate—especially for hospitality and restaurant brands where reputation directly affects revenue.

With no patch currently available, risk-reduction steps typically focus on limiting opportunities and limiting blast radius: consider uninstalling and replacing Ratatouille, restricting or disabling public registration where possible, auditing existing low-privilege accounts, and implementing server egress controls so the website cannot freely initiate outbound requests to untrusted destinations or internal-only services.

Similar Attacks

SSRF has been a recurring root cause or contributing factor in high-impact incidents because it can turn a public-facing application into a bridge to internal systems:

Capital One (2019) — widely reported as involving SSRF against cloud infrastructure, contributing to a major data breach.
Microsoft Exchange “ProxyShell” chain (2021) — a set of vulnerabilities including an SSRF component used in real-world exploitation.
