CVE-2026-39658

Vulnerability

Description CVE-2026-39658 is a missing authorization vulnerability found in the Panda Pods Repeater Field WordPress plugin, affecting versions from n/a through 1.5.12. The issue stems from the plugin's failure to properly enforce access control checks, allowing users to perform actions that should require higher privileges. Officially classified as a 'Broken Access Control' vulnerability, it arises from incorrectly configured access control security levels within the plugin [1].

Exploitation

Method Exploitation requires no special privileges, as the vulnerability can be triggered by any unauthenticated or low-privileged user. Attackers can exploit the missing authorization check to execute higher-privileged actions, such as modifying or deleting data that should be protected. The attack surface is wide, as the plugin is commonly used, and attackers often target such vulnerabilities in mass-exploit campaigns affecting thousands of websites regardless of traffic size or popularity [1].

Impact

Successful exploitation allows an attacker to bypass intended restrictions, potentially leading to unauthorized data access, modification, or other administrative actions. The CVSS v3 base score of 5.3 (Medium severity) reflects the moderate but real risk of unauthorized functionality being abused. Given that the vulnerability is present in a WordPress plugin, the impact can extend to site integrity and data confidentiality [1].

Mitigation

As an immediate action, users should update the Panda Pods Repeater Field plugin to a version above 1.5.12. If updating is not possible, it is recommended to consult with a hosting provider or web developer for temporary workarounds. The official advisory from Patchstack [1] provides further details and guidance.
