CVE-2026-32376

Vulnerability

Overview The Kalon WordPress theme, versions 1.2.9 and earlier, contains a missing authorization vulnerability. This issue, categorized as a broken access control flaw, stems from a failure to properly enforce authentication, authorization, or nonce token checks in certain functions. The vulnerability allows attackers to exploit incorrectly configured access control security levels within the theme [1].

Exploitation

Method Attackers can exploit this vulnerability without requiring any prior authentication, as the missing access control checks leave privileged actions unprotected. The flaw is particularly dangerous because it can be leveraged in mass-exploit campaigns, targeting thousands of websites simultaneously, regardless of their size or traffic levels. Exploitation does not require a valid user account or any specific privileges on the target site [1].

Impact

Successful exploitation enables an unprivileged or entirely unauthenticated attacker to execute higher-privileged actions that should be restricted. This could lead to unauthorized data access, settings modifications, or other administrative-level operations, depending on the specific vulnerable functionality within the theme. The CVSS v3 base score for this vulnerability is 5.3 (Medium), reflecting the potential for significant impact despite the medium severity rating [1].

Mitigation

The vulnerability has been addressed in a patched version of the Kalon theme. Immediate action should be taken to update the theme to the latest available version. If an update is not possible, site administrators are advised to contact their hosting provider or web developer for assistance in implementing temporary workarounds. The vulnerability is particularly concerning due to its suitability for automated mass-exploitation attacks [1].
