CVE-2025-69016

The auxin-elements plugin, which provides shortcodes and extra features for the Phlox WordPress theme, contains a missing authorization vulnerability in versions from n/a through 2.17.15. This flaw stems from incorrectly configured access control security levels, specifically a broken access control issue where authorization, authentication, or nonce token checks are absent, allowing unprivileged users to execute higher privileged actions [1].

Exploitation does not require authentication? The vulnerability is exposed to any visitor who can send crafted requests to the WordPress site. Attackers can exploit this by targeting publicly accessible endpoints that lack proper permission checks, bypassing intended restrictions. As noted in the reference, such vulnerabilities are frequently leveraged in mass-exploit campaigns against thousands of websites regardless of their traffic or popularity [1].

A successful exploit allows an attacker with low privileges (or no privileges) to perform actions normally reserved for higher-privileged users, such as modifying site configuration, injecting malicious content, or escalating privileges further. The exact impact depends on the missing authorization scope, but broken access control typically leads to partial or full compromise of the WordPress installation [1].

As an immediate mitigation, the vendor recommends updating the auxin-elements plugin to the latest patched version. If updating is not possible, site administrators should consult their hosting provider or a web developer to apply security workarounds, such as restricting access to sensitive plugin endpoints via web application firewall rules or custom code [1].
